The CMX983 is an Analogue Front End (AFE) IC that bridges the gap between a digital radio’s RF section and the DSP/FPGA.
Specifically designed to meet the needs of a Software Defined Radio (SDR). It is suitable for radio systems employing modulation bandwidths up to 50kHz in wideband mode and up to 25kHz in narrowband mode.
The CMX983 connects seamlessly with CML’s CMX994 Direct Conversion Receiver and the CMX998 Cartesian Feedback Loop Transmitter, to provide a complete small form factor, RF-to-digitised baseband solution.
The device is widely used in high performance wireless data systems including: military and satellite communication, professional two-way radio and wireless telemetry applications.

CMX983 and EV9830 Questions
Q. The EV9830 works intermittently with a PE0003 kit. Is there a problem?
A. The EV9830 and PE0003 has a hardware reset that should be toggled by the host. This pin is not accessible to the PE0003 so we recommend that C11 is replaced to extend the time that the hardware reset is held low during power up. Guidance for the location and replacement of C11 is given in the latest EV9830 User Manual. This replacement is only required on early EV9830 kits.
|EV9830||The EV9830 Evaluation Kit allows evaluation of the CMX983 Baseband Interface for Digital Radio. For evaluation of the Fractional-N synthesisers, a 900MHz VCO is fitted with connections to synthesiser 1 and a 2.1GHz VCO is fitted with connections to synthesiser 2. Test pads are also provided for connection to an external VCO.||EV9830_Product_Preview
