The EV9750 is a demonstration and evaluation platform for the CMX975.

The CMX975 provides functionality consisting of RF PLL/VCO + IF PLL/VCO + Transmit Up-convert Mixer + Receive Down-convert Mixer + LNA. It has been designed to interface with the CMX973 to provide a simple and cost effective RF transceiver for operation in the range 1 to 2.7 GHz. The EV9750 design incorporates a CMX973 to allow conversion to and from the CMX975 IF frequencies to I/Q baseband signals. 

The CMX975 provides a 700MHz to 6GHz 24-bit Fractional-N RF PLL and an internal RF VCO covering 2.8 to 3.6 GHz. A separate integer-N IF PLL and VCO for 900MHz is also provided. An inductor value change can configure the IF VCO to cover other frequencies.
