General Description

The CMX983 is an Analogue Front End (AFE) IC that bridges the gap between a digital radio’s RF section and the DSP.

Specifically designed to meet the needs of a Software Defined Radio (SDR), the CMX983 performs critical DSP-intensive functions, provides dual channel analogue to digital and digital to analogue conversion, includes two RF fractional-N synthesisers, and embeds a host of auxiliary ADCs and DACs for use within the radio system.

The CMX983 meets the low operating power requirements of SDR terminals and is powered from separate 3.3V and 1.8V power supplies.
