This video discusses the four different types of constellation diagrams that can be viewed with our QAM Multi-mode wireless data modems, our CMX7163 and CMX7164 devices.

The datasheet for CMX7163 can be found here: http://www.cmlmicro.com/products/CMX7...

The CMX7163 and CMX7164 provide 4/16/64-QAM baseband modem functions in a single chip, replacing the current need for user programmed DSP plus codec ICs.

This development includes high dynamic range analogue signal capturing, digital baseband filters, auxiliary codecs, clock generator, and I/O functions all designed to lower total BOM cost and chip count. The high level of total integration reduces technical risk and time to market.

The device is a complete baseband modem system delivering high performance and high spectral efficiency QAM for narrowband applications. These include M2M systems over dedicated channels, digital Software Defined Radio (SDR), high-speed wireless data and SCADA systems.
