Brief Description The EV9942/EV9942A/EV9942E allows the user to investigate all aspects of the CMX994 integrated circuit, which implements a high-performance direct conversion receiver. The evaluation kit also includes additional circuits that may be used to evaluate system performance, a high-frequency VCO and an optional Fractional-N PLL. Access is provided to all CMX994 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 overall frequency range of this evaluation kit is for RF frequencies between 100MHz and 940MHz, with default operation at 448MHz. The CMX994 is controlled via its C-BUS serial interface. The PE0003 Interface Card is available separately to support PC-based control of the EV9942/EV9942A/EV9942E. The PE0003 uses ES9942xx.exe PC software, part of the ES9942xx.zip file, which is available from the CML website. 2015 CML Microsystems Plc 2 UM9942/5
