CML PMR / APCO/Tetra
The Flexible Two-Way Radio Processor
Product ID: CMX7031/41

As a CML product built on FirmASIC®  technology, each of these two similar ICs can be configured, by Function Image file to one of three individual functions: as either a Full-Feature Two-Way Radio Processor as a 4-Level FSK Modem or as a C4FM Modem.
Additionally, the CMX7031 version offers two on-chip RF synthesisers. The CMX7041 versions do not offer the RF synthesisers.

Please use the links below to visit the product overview of your choice, download specification etc:

The overall CMX7031and CMX7041 product functions and feature-sets are determined by a Function Image which is a data file that configures the on-chip internal systems. The Function Image can be stored in the Host microcontroller’s FLASH memory and uploaded to the CMX7031 after power-up or transferred to an EEPROM attached to the CMX7031 for automatic uploading of the data file after power-up.
