描述 Description

The CMX7031 and CMX7041 are half-duplex processor IC platforms using FirmASIC technology, that are suitable for use in multi-standard analogue Two-way Radio (TWR) systems.
FirmASIC component technology allows on-chip sub-systems to be reconfigured by a Function Image (FI): this is a data file that is uploaded during device initialisation that defines the device’s function and feature set.
The CMX7031/CMX7041 enable a revolutionary new platform approach to radio design, enabling multi-mode analogue two-way radios to be developed based on a single radio platform, conforming to many systems: PMR, LMR, Trunking, Marine, Aviation, Amateur radio, NOAA weather radio and packet data radio.
To enable full control of the radio functions and minimise the overall chip count, two user programmable system clock outputs are provides along with auxiliary ADC and DAC blocks. A user-programmable PLL, driven from the Xtal/reference clock input, generates all internal clocks and allows one clock source to be internally reused for both baseband and RF synthesiser functions (for CMX7031 only). A flexible power control facility allows the device to maximise powersaving whilst not processing signals or when specific functions are not enabled.
