Brief Description The EV9910B allows the evaluation of the CMX991 RF Quadrature Transceiver and the EV9920B allows the evaluation of the CMX992 Quadrature / Low IF Receiver. Both Evaluation Kits use the same printed circuit board, but with different components fitted. This User Manual is also common to both kits. The CMX991 is an RF Transceiver IC providing I/Q modulator and up-conversion, superheterodyne receiver and IF local oscillator. The CMX992 includes only the receiver and IF LO sections of the CMX991 and is ideal for applications that do not require the CMX991 transmitter, for example when a linearised transmitter is required, in which case the CMX998 Cartesian Loop Transmitter IC could be used for Tx and the CMX992 for Rx. 2010 CML Microsystems Plc Evaluation Kit for CMX991 and CMX992 EV9910B/EV9920B Access is provided to all CMX991 (CMX992) RF, baseband and control signals by either connector or test points. Test access points are available to accept common test equipments, such as RF and baseband signal generators and spectrum analysers. All signal paths are matched by suitable components. The EV9910B also provides an optional lumped bandpass filter plus buffer amplifier at 460MHz (default) to aid evaluation. The overall evaluation frequency range of this Evaluation Kit is for RF frequencies between 100MHz and 1GHz, with default operation over 450MHz to 470MHz. In the form of a populated PCB, this flexible Evaluation Kit enables users to configure and evaluate the CMX991 (CMX992) devices for various applications and frequency bands. The on-board CMX991 (CMX992) is controlled via its C-BUS serial interface. The PE0002 Interface Card is available separately to support PC-based control of the EV9910B/EV9920B. The PE0002 uses ES9910xx.exe PC software, part of the ES9910xx.zip file, which is available from the CML website. This software enables the PE0002 to control either an EV9910B or an EV9920B Evaluation Kit. 2010 CML Microsystems Plc 2 UM9910/6
