The CMX7031 two-way radio processor is touted by CML Microcircuits to enable a revolutionary new platform approach to radio design. This new product provides a comprehensive feature-set as standard plus a roadmap of function enhancements available through the company's FirmASIC technology.

Suitable for implementing professional radio (PMR/LMR and Trunking), leisure radio (GMRS, FRS, PMR446, and MURS), marine VHF, aviation and amateur radio products, the CMX7031 is a full-function, half-duplex, audio, signaling and data processor IC that provides concurrent sub audio-band and in-band signaling, complete audio processing and a comprehensive data modem implementation. The data modem provides a free format data mode and a robust flexible packet data mode, utilizing CRC, FEC, interleaving and scrambling. The device features two on-chip RF synthesizers that can be used for efficient switching between Rx and Tx operating modes; two user programmable system clock outputs; and auxiliary ADC and DAC blocks to enable full control of the radio functions and minimize overall chip count.

In addition, a user programmable PLL generates all internal clocks and is driven from the Xtal/reference clock input. This supports a wide selection of Xtal/reference clocks and allows one clock source to be internally reused for both baseband and RF synthesizer functions, explained CML. A flexible power control facility allows the device to maximize power-saving while not processing signals or when specific functions are not enabled. Tx Enable and Rx Enable output pins can be used to conveniently control external RF circuits. A single command from the host microcontroller, via C-BUS, can instruct both the internal CMX7031 systems and external circuits to change between Tx and Rx operating modes.

Available in VQFN and LQFP packaging, the CMX7031 radio processor has a low power 3V to 3.6V operation.
