CML's CMX7041 two-way radio processor is the second product in a platform approach to modern two-way radio design.
It is a full-function, half-duplex, audio, signalling and data processor IC, suitable for implementation in professional radio (PMR/LMR, trunking etc), leisure radio (GMRS, FRS, PMR446 and MURS), marine VHF, aviation and amateur radio products.
It provides concurrent sub-audio band and in-band signalling, audio processing and a data modem implementation. The FFSK/MSK modem provides a free format data mode and a flexible packet data mode, using CRC, FEC, interleaving and scrambling.
The device features two on-chip RF synthesisers that can be used for efficient switching between Rx and Tx modes. Additionally, two user programmable system clock outputs are provided and auxiliary ADC and DAC blocks are provided to enable full control of the radio functions and minimise the overall chip count.
A user-programmable PLL generates all internal clocks and is driven from the Xtal/reference clock input.
A flexible power control allows the device to maximise power-saving while not processing signals or when specific functions are not enabled.
