1. Brief Description
The EV9902 Interface Kit forms part of the CMX990 GMSK Packet Data Modem and RF Transceiver IC
evaluation and investigation resource. The EV9902 Interface Kit provides a graphical user interface (GUI)
for the EV9900A (CMX990) EvKit. The EV9902 is supplied as a Hyperstone hyBoard-XS evaluation
board plus an interface card, together with GUI software for a PC. This kit connects simply to a Windows-
based PC via a standard USB cable. The connection to the EV9900A EvKit is via the supplied ribbon
cable.
The supplied ES9902 GUI software allows users to directly write to and read from the CMX990 registers
and perform real-time tasks for Mobitex or free-format frame transfers live over a RF link. The GUI
software will calculate the CMX990 register values required to generate the user’s desired PLL
frequencies and bit rates. The hyBoard-XS evaluation board is supplied pre-loaded with firmware that
allows the real-time operations to be performed. Please note that this kit is not suitable for use with the
EV9900 EvKit. Users requiring support for this older kit should contact [e-mail].
