AX.25 Modem
CMX7031/CMX7041
The CMX7031 features two on-chip RF synthesisers, with easy Rx/Tx frequency changeover, and
programmable system clocks to minimise chip count in the final application.
The CMX7041 is identical in functionality to the CMX7031 with the exception that the two on-chip RF
Synthesisers have been deleted, which enables it to be supplied in a smaller package.
Other features include two auxiliary ADC channels with four selectable inputs and up to four auxiliary DAC
interfaces (with an optional RAMDAC on the first DAC output, to facilitate transmitter power ramping).
The device has flexible powersaving modes and is available in both LQFP and VQFN packages.
Note that text shown in pale grey indicates features that will be supported in future versions of the device.
