General Description

The CMX7131/CMX7141 with 7131/7141FI-2.x implements a half-duplex 4FSK modem and a large proportion of the DCR Air Interface, Data Link and Call Control layers.

In conjunction with a suitable host and a limiter/discriminator based RF transceiver or CMX994 Direct Conversion (I/Q) receiver, a compact, low cost, low power digital PMR radio conforming to ARIB’s T98 Digital Convenience Radio standard can be realised.
