CML Micro CMX7143 Multi-Mode Data Modems

CML Micro CMX7143 Multi-Mode Data Modems, featuring FirmASIC® technology, can be configured by a Function Image™ (FI) file to one of three individual functions: GMSK/GFSK Packet Data Modem, 4FSK Packet Data Modem, or FFSK/MSK Modem. The FirmASIC IC function and configuration are achieved by the loading of a compact Function Image file at start-up or when a change of data scheme is required.
