CMX980A Overview
This device is intended to act as an interface between the analogue and digital sections of a Digital Radio System, and performs many critical and DSP-intensive functions. The chip is designed with the necessary capability to meet the requirements for use in both mobile and base station applications in Terrestrial Trunked Radio (TETRA) systems, but the architecture is sufficiently flexible to allow use in other...
