Giving A Helping Hand To Digital Radio Designers

June 2005

CML’s progress into the world of TETRA, APCO 25, Tetrapol and the Japanese RCR and ARIB digital radio systems, accelerated with the recent launch of the CMX981 ultra low power digital radio baseband processor IC, with on-chip voice codec/processor and audio PA.

CML now announces the EV9810 evaluation kit, for experimentation and speedy design-in of the CMX981, giving digital radio designers more than a helping hand.

Comprising of a low noise-floor digital/analogue PCB and an on-board CMX981 device, the evaluation kit provides access to the CMX981’s baseband signal, control and data interfaces (Differential and single-ended baseband interface, buffered control and data interfaces with level shifting), as well as its ADC and DAC on-chip functions. Additionally, an onboard audio codec interface provides microphone, earphone and loudspeaker inputs and outputs via jack sockets. On-board power regulation and distribution is provided, along with a 9.216MHz device clock.
