CMX7031 The Two-Way Radio Processor

The CMX7031/CMX7041 FI 1.5 is a full-function, half-duplex, audio, signalling and data processor IC. This makes it a suitable device for both the leisure radio markets (FRS, MURS, PMR446 and GMRS) and for professional radio products (PMR/LMR, Marine and Trunking) with or without signalling and data facilities. The device utilises CML’s proprietary FirmASIC .
