 Hello everyone and welcome to this webinar about the ST60 transceiver for contactless connectivity. My name is Fabrice Gendron et I'm the marketing manager for the EME region. I'm very pleased to be with you today to talk about our latest ST60 transceiver, which is a millimeter weft product that delivers very high data rights for short-range contactless connectivity applications. Here is the agenda of today's webinar. I will start with a brief introduction regarding the positioning of ST60 in wireless technologies, followed by its key product features and performances characteristics. And then I will discuss how the ST60 can be implemented in a contactless Ethernet solution. My colleagues Gérome and Tariq will then demonstrate two reuse cases, the first involving a contactless Ethernet module developed by one of our partners and the second using our dedicated evaluation kit with various antenna configurations. And finally I will describe the key benefits of the ST60 and how you can quickly begin evaluating its performances and potential. I will wrap up with an interactive Q&A session. Let's begin by exploring how the ST60 compares with other wireless connectivity strategies and the new world of possibilities that this technology offers. We introduced this very recent addition to ST's portfolio for the first time at embedded world in 2019. So what is ST60? In short, it is a very low-powered transceiver operating on a carrier frequency of 60 GHz, which is in the unlicensed V-band. It delivers very high data communication rates ranging from a few Kbps up to 6.25 Gbps and can pass through materials such as plastic and wood but not conductive materials. From the onset, the ST60 was designed to offer industry lowest power per bit. Here we have two charts. The chart on the left shows data throughput versus power consumption and on the right, the chain is throughput with distance. Both charts compare the performances of the ST60 with several common wireless connectivity technologies such as Wi-Jig, Wi-Fi, Bluetooth, and NFC. Returning to the first chart, you can see that the power consumption of our transceiver is comparable with Bluetooth even though Bluetooth has a far lower data transmission rate. So the ST60 clearly wins this contest in terms of performances and power budgets. The second chart on the right shows how the various connectivity technologies perform over operating ranges. So you can see that the ST60 delivers high speed performance for short distance data communication up to 10 cm. In this sense, it is comparable with NFC but able to support much higher data rates up to 6.25 Gbps. In short, this new solution enables high speed, low power, short range, point-to-point contactless connectivity and is an ideal replacement for all the cables and connectors used in board-to-board or device-to-device data communication which we all know can cause failures and are burdens on manufacturing cost and design complexity. The new ST60 can greatly simplify many design challenges involving waterproof, corrosive proof, and dust proof operation in a medically sealed environments while maintaining high speed data links. Let's examine some real solutions the ST60 can offer by replacing wired connection in high speed data applications. One highly successful application is LED displays which you find in indoor and outdoor environments in stadiums, in office buildings, and in airports. Multiple LED display modules are normally connected through Ethernet cables and connectors to build a display wall. With the ST60, you can build a full plug-and-play type solution and replace Ethernet cables and connectors with contactless video links hence removing the onsite work required to connect the LED modules, improving reliability and cutting cost. In personal electronics applications like smartphones and wearables, the ST60 can replace all the connectors for internal board-to-board communication and external device-to-device communication. These benefits can be combined with wireless power transfer solution from ST to develop truly waterproof, dust proof, and connector-free products for end-users. In industrial systems heavily exposed to harsh environments or mechanical stresses which could compromise wired connections, the ST60 allows virtual freedom of movement with contactless data links data far more robuste against environmental and operating conditions, including shock, vibration and rotation, as well as protecting sensitive electronic devices by providing natural galvanic isolation. In factory automation, imagine simply placing a product on a programmer, or vice versa, to immediately establish a connection and start exchanging data. For example, to flash or test a product during manufacturing. The ST60 can solve many issues requiring robust data transmission and therefore increase manufacturing availability and productivity. Now let's have a look at the key features and performances of the ST60. Here you see the block diagram and some key features. The ST60 is a fully integrated transceiver operating in the ST60 gigahertz V-band. It is a highly integrated and compact design with transmitted and received pass, digital control and power management with single or dual power supply in a verisible footprint. Dual supply offers slightly lower power consumption while single supply offers a more straightforward implementation. The device can be configured through either an as-per-see bus or directly through hardware control pins, which is the easiest way to set the direction and the operating mode. The point-to-point wireless link connectivity operates in half-duplex mode using the highly effective amplitude-chief-key modulation scheme with about 24 dB typical total language chat. The device supports either a single and with CMOS IO interface from a few kilobits per secondes to 100 megabits per secondes or differential SLVS Therix Air exports for data transfer up to 6.25 gigabits per secondes. The device features exceptional power management consuming 40 milliwatts in full transmit mode at 5 gigabits per secondes, 25 milliwatts in receive mode and only 1.3 microwatts in off mode. It comes in a very small VFBGA 2.2x2.2 mm package and offers a reduced bill of materials because there is no need for external RF components, no balloon, no machine network and no external reference clock. The only things it requires is an antenna which I will detail in the following slide. The ST60 can be configured through either the as-per-see bus or hardware control pins to support different operating modes and data-rate modes. Three configurations are available. Two, using the SLVS differential input-output port Therix AirX which needs to be DC balanced and 8-bit 10-bit data coded to enable add a full data-rate mode from 1 megabit per secondes up to 5 gigabits per secondes or high data-rate mode from 500 megabits per secondes up to 6.25 gigabit per secondes. This mode is usually used only for data-rates above 5 gigabits per secondes. The typical application shown in the block diagram implements two ST60 devices on each side with SLVS connected to the Ethernet-HGMI interface to form a contactless gigabit Ethernet link. Note that if customer wants to use FDR or HDR modes the ST60 must be connected with the OS device that supports the SLVS or LVDS interface for example FPGA or HGMI Gigabit Ethernet file. The last configuration is using the single-ended CMOS IO to enable low data-rate mode from 9.6 kilobits per secondes up to 100 megabits per secondes. The typical application shown in the block diagram of ST60 devices on each side with CMOS IO connected to the UART-TX erics of a microcontroller to enable contactless full-duplex UARTs without a cable and without altering any lines of code. For the antenna the ST60 supports three different antenna configurations depending on the distance and coping requirements of your application. The antenna unborn or patch antenna configuration in the middle is embedded on the PCB using very inexpensive FR4 material. It supports a 3-space distance of 1.5 cm to 3 cm depending on the data-rate mode. The patch antenna delivers vertical communication and is typically suitable for device-to-device connectivity with one device on top of the other. For horizontal communication then we have something called the ON antenna picture on the right. These ON antennas have been developed in partnership with a company named Radial. They are mounted directly onto the surface of the PCB and are compatible with pick-and-place processes. The higher gain makes it suitable for 3-space distance of 3 cm to 5 cm. These antennas are available in either vertical or horizontal polarization so they are very suitable for multi-link applications thanks to the isolation between H&V polarize signals typically to enable full-duplex link. The final antenna and package configuration shown on the left is directly integrated into the ST60 package. It offers the smallest form factor but the lower gain means it is only suitable for very short distance of a few millimeters can be used for board-to-board communication in a device or to provide galvanic isolation in a board. In the next set of slides I will focus on a typical application of the ST60 involving contactless Ethernet communication. More and more applications require Ethernet-based connections but the Ethernet RJ45 connector is not produced to numerous plug-and-plug for matting cycles and not resistant to corrosive elements dust, liquids and similar environmental conditions. This has generated wide interest in removing the RJ45 connector which is where the ST60 comes in. An application that makes extensive use of Ethernet connection is to connect multiple LED display modules in a wall display and transmit the video stream to the different part of the display. We know that Ethernet cables and connectors add cost and complexity to the production and assembly of the wall display. The ST60 resolves these issues and as most of the time there is already an FPGA onboard the cost can be further reduced by eliminating the Ethernet file and connecting the SLVS input-output port of the ST60 directly to the FPGA. In factory automation the ST60 allows full 360° movement freedom which can be particularly beneficial for industrial robots whose movements are often restricted to avoid damaging the many cables and connectors crossing the different zones. The ST60 therefore provides a wireless bridge across the different part of a robot. In industrial and security cameras contactless Ethernet communication can allow plug and play modules again eliminating the need for expensive high-speed data cables and connectors and readability issues caused by things like cable rotation. It also makes devices more compact, smaller and slimmer thanks to the removal of the cables and RJ45 connectors. Finally, the ST60 allows a new kind of contactless hermetically sealed Ethernet connectors to replace costly IP6X connectors eliminating the need of expensive Ethernet file and magnetics especially in 2.5 Gbps or 5 Gbps Ethernet links and making Ethernet connections modular and sealed. This is the block diagram of a potential configuration to replace an Ethernet cable connecting a PC on the left to a server on the right. Both sides have onboard RJ45 connectors as well as a Gigabit Ethernet file with native HGMI interface support connected directly to 2 ST60 through the SLVS input-output ports. You need 2 devices in parallel on each side to enable a full duplex link with separate transmit and receive pass as a single ST60 can only support all duplex operation. This configuration enables a Gigabit contactless Ethernet full duplex link supporting 10, 100 and 1000 Mbps. It does not require a clock on the TX or ERIC side and the actual clock data recovery is provided through the Ethernet file. It is available in antenna on board configuration for vertical transmission and on antenna for horizontal transmission. Depending upon the antenna configuration the Ethernet signal can be transmitted up to a distance of a few centimeters. The Ethernet protocol unders all connection issues such as broken links so that transmission errors can be detected and recent. The use of a 5 Gigabit per second file can be used to create a 5 Gigabit per second connection in the same way. If you want to quickly begin evaluating contactless Ethernet connectivity then you can use this SK202A and B modules with the own antenna. These modules were developed by EPS in China in partnership with Radial for the own antennas. Each module consists of a main board hosting the RJ45 connector the magnetic transformer and the Gigabit Ethernet file with HGMI interface. An IRF toaster board hosting 2 ST60 and 2 ON antennas with H and V polarisation is soldered on the motherboard. If we zoom on the IRF boards you can see that the polarisation of the ON antennas is inverted on each board. Your final application should integrate the IRF board components directly onto the main PCB for cost saving purpose and ST provides design guidelines to help you build your integrated solution. Alternatively, you can source the module directly from EPS. The second version of the module implements antenna onboard with exactly the same features as the first set but designed for vertical communication so that you have the two board sitting on top of each other to enable the link as shown on the picture. In these modules made by EPS the ON antennas are replaced with two single patch protein board antennas as shown on the left side. The rest remains the same with RJ45 connector magnetic transformer and Gigabit Ethernet file with HGMI interface to connect to the ST60 devices. Now we should pass over to Jerome for the first unzone demo of this contactless Ethernet modules. Ok, thank you Fabrice for your introduction. Now let's switch to the module himself so this is the two flavour of the module of the Ethernet module done by our partner which is EPS and the first one which is 202 for all horizontal transmission come with all antenna so this is so it send from this to this and then back to using the antenna and for vertical transmission we are using the second flavour which is 201 and with a patch antenna ST60 is there so it's quite small it's 2 by 2 millimeters and we have one for sending and one for receiving Ok, now let's switch to the setup using a real Ethernet cable to show you the performance and then we will show exactly the same setup using ST60 to see the magic Ok, so here you have STM32 MP1 board which is running a network drive on it with some content into SD card and I will transfer the content of this SD card using the gigabit network cable to the laptop as you can see we have 200 megabits transfer from the MP1 to the laptop again, it's limited by the SD card himself Ok, so now I will show you the latency of the network from the laptop to the MP1 so the latency is quite low it's around 1 millisecond and the third step is to show you since we have some limitation due to SD card for throughput transfer so I will use another tool called IPERF which is a standard tool and I have an IPERF server which is running on the board I have an IPERF client which is running on this laptop and I will show you gigabit transfer in between so as you can see we are close to 900 megabits per second Ok, remember the EPS module so we have a nice casing and we have some magnets to have some contactless Ethernet module so due to demo constraint and to limit the amount of cable on the demo I put some battery in it just for demo purpose but this is the same same module let's set up the magic so I will just plug my first Ethernet module to the laptop and so I remove the previous cable which is go to MP1 so now this module is connected to the laptop and I will use this cable to connect the second module Ok, so now we have introduced the Ethernet module and I have made no modification no hardware modification on to the free step I've made just before so the first one was to transfer a file from the MP1 to the laptop second step was to show latency, network latency and the last one was throughput let's start by the beginning with 5 transfers so we have exactly the same throughput with ST60 and as you can see it stops and then it back to transfer so now I will show you network latency so as you can see it's close to 1ms same as before and if I open longer, so it stops and it's back just after ok, first step is to show you so high throughput 3 again so we are close to 900mb and again if I open the network it stops and back again ok, so now I will demonstrate a video playback so the content is still on this MP1 board is go through ST60 and then to my laptop so I use the standard tool BLC so media open I remove a bit caching and then I select my file and then send my playback ok so now the content is play through internet module and then if I open the link it stops playback ok, now if I restore the link thanks to internet protocol which under broken link playback is now continuing directly now I can open a bit few cm to see that it's still working and that will use several material cardboard no impact plastic no impact plexiglass and then metalize pad which block so as expected you can see that it stops everything and if I remove it it will start audio first and then back to video thank you Thank you des connecteurs SME, pour connecter à des équipements IRF et un jumper configuration si vous souhaitez configurer la ST60 par hardware. Vous pouvez aussi interfacer cette borde avec les Bordes STM32 Nucléos pour configurer la ST60 à travers le bus de l'aéroport. Ce borde smart est compatible avec différents modules ST60 IRF, supportant les différentes onténa configurations, intégratées, patchs ou on-onténa, et avec un single ou dual ST60 pour un duplex ou la communication du duplex. Cette équipement de l'aéroport est principalement pour permettre aux utilisateurs d'obtenir des mesures pour les diagrams de l'oeil, les rètes de la bataille, et les jeteurs, selon la distance entre les onténa et le matériel entre eux. Freer, plastique, glace, etc. Ici, c'est un observateur des modules d'aéroport de l'aéroport de l'aéroport de l'aéroport qui vous permet d'évaluer la communication port-à-port, combiner l'antena en package ou l'antena en borne ou les on-onténa, avec les distances typiques que vous pouvez achever. Notez que vous pouvez combiner l'antena en package avec l'antena en borne ou l'antena en package avec l'on-onténa, pour augmenter la distance vers les deux antennes en package. La distance la plus longue possible est achetée quand combiner l'antena avec l'on-onténa. Notez que les distances sont estimées à 1,25 gigabit par seconde. Nous recommandons de commencer la pièce d'évaluation en mode Hardware First et ici vous pouvez voir la configuration typique de les jumpers et le signal passe à être utilisé pour évaluer la mode low-data en mode à gauche en utilisant le CISWKP single-ended CMOS IO pour transformer la data à 100 Mbps et la mode high-data en mode à droite en utilisant les portes d'input d'input d'outil pour transformer la data à 6,25 gigabit par seconde. Je passe maintenant au Tariq pour la seconde demo en zone en mode en utilisant la pièce d'évaluation. Merci Fabrice et merci tout le monde d'avoir participé. Dans cette petite vidéo, nous ferons deux mesures sur la pièce d'évaluation ST60A2. Mais d'abord, let's have a look at the ST60A2 portes offert par ST. Nous avons adopté un approche modulaire avec l'optimisation d'une pièce d'évaluation pour être placée sur les portes d'évaluation. Cet approche nous permet de changer entre les portes d'évaluation et vous enable de connecter les portes d'évaluation dans une phase de prototype. Nous pouvons voir ici les portes d'évaluation que nous avons développées. Merci à notre partenaire Radial, nous avons utilisé les antennes de horn qui sont radiées en parallèle avec la PCB. Ici, il y a une pièce d'évaluation ST60A2 avec deux portes d'évaluation ST60A2 en mode simple et aux directions opposées. Avec les mêmes antennes de horn, ici il y a une pièce d'évaluation ST60A2. Ici, il y a une pièce d'évaluation ST60A2 avec une antenne de horn pour transmettre la pièce d'évaluation ST60A2 à la PCB. Enfin, ici il y a une pièce d'évaluation ST60A2 avec une antenne intégrée dans la pièce ST60A2 en mode saveur. Ce sont deux portes d'évaluation sur les portes d'évaluation ST60A2 que nous pouvons pluger toutes les portes d'évaluation ST60A2. Ceci est pour ldr mode qui s'étend pour l'évaluation d'évaluation ST60A2 comme les conditions d'évaluation ST60A2 et d'évaluation d'évaluation d'évaluation ST60A2. Cette profondeurCan be used to evaluate all the features of the ST60A2 de données avec des rates de 1 gigabit par seconde à 625 gigabit par seconde. Ce rate de données correspond à des signalés de haute vitesse, comme 1 gigabit d'éthernette, une Vx1 ou 5 gigabit d'éthernette. Donc, une quête de 4 valeurs est composée de 4 bords. 2 bords d'évaluation sur lesquels les bords de référence RF sont plagués. Avec cela, nous pouvons valider les bords de ref et les performances de l'éthernette, et vous pouvez aussi développer votre application. Alors, nous allons avoir un plus grand regard sur les bords de référence. Parce que nous allons l'utiliser dans nos mesures. La borde de référence RF est plague ici. Les données différenciées pour être transmissées seront passées par ces deux connecteurs, et les données reçues seront passées par ces deux connecteurs. Les données LDR pour être transmissées sont passées par ce connecteur, et celui-ci est pour les données reçues. La borde de référence RF est plague ici et a besoin d'un supply de 3,3 volts. La ST60A2 peut être opérée dans le mode standalone, ce que nous appelons hardware forced. D'où le mode de transfert est sélecté en utilisant un bootstrap, et aucune programmation est nécessaire. La configuration de mode de transfert est faite par ces jumpers, et 3 modes de transfert peuvent être sélectés. La mode LDR, dont je l'ai mentionnée, est tendée par la mode FDR, qui est pour la transition de data de l'espoir de 1 Mbps à 5 Gbps. Finalement, la mode HDR, ou la mode hiédat, qui nous enneprime de transfert de data de l'espoir de 6,25 Gbps. La ST60A2 peut être opérée en mode I², avec le accès à la gestion des smartphones. Il est possible de connecter l'application via ces connecteurs Arduino avec un SDM32 Nucleo-Board qui est utilisé pour contrôler un GUI délicaté à l'application SD68-A2. Alors, allons-y dans la démonstration maintenant. Nous allons premièrement faire un diagramme de l'IDI et le measurement GITER dans le mode HDR. Ici est notre équipe d'évaluation. Il est configuré dans le mode HDR. Un board va transmettre le signal et l'autre va le recevoir. Nous allons configurer notre générateur de signal. Les setés d'application s'amplifient à la démonstration SD68-A2. C'est-à-dire 200 millivolts amplifiés sur chaque ligne, centré sur 200 millivolts. Ce qui signifie un signal différentiel amplifié de 400 millivolts à plus de 100 ohms d'impedance différentielle. Ici, j'ai choisi le pattern de données. Dans le mode différentiel et en commençant par 100 millivolts par seconde, le SD68-A2 doit travailler sur 8 bits, 10 bits de données codées pour garantir la distribution de 0s et 1s. Ici, nous avons choisi la séquence PRBS7, car elle a des propriétés similaires comme 8 bits, 10 bits de données codées. Maintenant, nous avons terminé avec la démonstration. Nous allons tester 6,25 gigabits par seconde, ce qui est le maximum supporté par le SD68-A2. Cette démonstration correspond à la démonstration de 5 gigabits pour laquelle un code de 8 bits, 10 bits de données codées sera ajouté. Cela correspond également à la démonstration de l'interface Arzovi qui correspond à la démonstration de 10 gigabits par seconde de 2, 6,25 gigabits par seconde. Maintenant que la démonstration est configurée, nous allons connecter à l'évaluation de la transmission. Sur le côté de la recueille, nous connectons l'évaluation des outils pour une oscilloscope pour un diagramme 9 et l'analyse de Jeter. N'oubliez-vous que c'est essentiel d'assurer que la oscilloscope et la PRBS caractéristiques, comme les bandwidths et la démonstration, sont compatibles avec les données de la signal que vous voulez analyser. Une dernière question sur les câbles utilisés ici. C'est essentiel d'assurer qu'ils sont compatibles avec les fréquences que vous voulez tester. N'oubliez-vous que les WR et l'insertion sont compatibles et n'oubliez-vous d'utiliser les câbles matchés afin de ne pas introduire la recueille entre les points positifs et négatifs. Nous sommes maintenant prêts à faire notre measurement et je vais utiliser l'installation automatique de l'oscilloscope. Lorsque l'oscilloscope fait le measurement, j'aimerais ajouter que vous pourriez également mesurer la démonstration plutôt qu'à l'aide de Jeter. Le measurement de l'oscilloscope fait plus de temps. C'est up to you to choose whether to make a BR or Jeter measurement. It can be depending on the specification you have, whether you have a Jeter's mask or a bitter rate limit. Back to our measurement and I see that we've already got the result. The oscilloscope displays many waveforms and figures including the Jeter distribution and the eye diagram, which as you can see is wide open for a 6.25 Gbps data rate and about 12 mm space between the antennas. We also get the total Jeter, around 52 picoseconds here. And it's component so you can have a look at the random Jeter and deterministic Jeter. You may want to transmit the signal through plastic. So let's see how the Jeter evolves when there is some plastic between the two antennas. The signal power received by the antenna decreased because it's been attenuated by passing through the 2 mm thick piece of plastic and this leads to a different eye diagram and a bigger Jeter. Here 58 picoseconds, 6 picoseconds more than previous result. Let's now make a measurement in LDR mode. I will show you a latency measurement which is an important parameter between different solutions and connectivity standards. Ok, I need to change the setup. Select LDR mode, use a different generator, set the data rate to 1 Mbps, the voltage swing to 1.8V. I have connected the generator output to the evaluation kits input port. On the oscilloscope, I connected a copy of the transmitted signal and the received signal. Let's measure the time difference with the received signal. Here we see it is in the 9 Ns range. Ideally, I would recommend measuring the latency of the test setup without the device and then subtracting it from this result to get an accurate value. It is just for the sake of the demo that we are keeping it simple today. I've used cables of the same length so I'm measuring the latency of the evaluation kit from one connector to another. This measurement done this way gives us already a fair idea on the ST-60A2 latency around 8 Ns. This is all that I wanted to show you today. So what are the main takeaways of this video? ST's ST-60A2 evaluation kit offer is varied and you have wide choice from which you can order one for your application. I've demonstrated that the ST-60A2 can transmit data at a rate of 6.25 Gbps without problem, proving that we are compatible with standard high data rate transmission schemes. You can use our boards for performance evaluation and check GTAR-BER versus data rate propagation distance and medium. For sure, this should always be done with respect to target specification. Very small latency is one of the key features of the ST-60A2 versus other wireless standards. Thank you, Tariq. We are now close to the end and I would like to summarize the key points related to this new technological solution enabling contactless connectivity. The most important benefit of the ST-60A2 is obviously its cable-like contactless connectivity. While it provides the same performance as cable connectivity in terms of data rate, GTAR and PING, it offers greater reliability than cables and connectors, laur cost, et beaucoup plus de robustness à l'environnement et la condition d'opération. The ST-60A2 supports very high speed data communication up to 6.25 Gbps, making it suitable to replace the widely used Gigabit Ethernet-Base communication. One ST-60Base link can replace five Ethernet links at 1 Gbps. The device comes in both consumer and extended industrial temperature ranges from minus 40°C to plus 1.5°C. It supports several antenna configurations for side-by-side of top-bottom data transmission and there is also a version with integrated antenna. And finally, it is cost-optimized in terms of build of materials with no need for external RF components and a miniature footprint of less than 5 square millimeters. To summarize, the ST-60 opens a new world of possibilities for your product design by enabling high speed, low power, short range, point-to-point contactless connectivity. Here is what you can do to get started with the ST-60. The ST-60A2 product brief est available on ST website together with a short overview. And there are three very good videos on YouTube. The first from ST Online Embedded World Tour 2020 which demonstrates the contactless Gigabit Ethernet connection using the EPS modules. The second one from ST at Consumer Electronics Show 2020 which demonstrates ST-60 application in LED display modules and the third one from ST Embedded World 2019 that demonstrates wireless UART through a plastic box. The above resources will provide a good overview of this product and how it can be used in various types of industrial, medical and consumer applications. You can then progress to performance evaluation and application development. An ST can provide comprehensive supporting materials including full data sheets, antenna design guidelines, evaluation kits and samples under a non-disclosures agreement. In this case please contact either your local ST search representative or myself and I will be very pleased to support you. I would like to thank you all very much for your attention and I hope that this presentation has provided you with better idea of the key features and benefits of this new solution.
