CML Microcircuits has added to its two-way radio IC range with the CMX138 audio processor.

The product features a user-programmable frequency inversion half-duplex audio scrambler, an audio processing path (consisting of companding, pre/de-emphasis and level setting), with concurrent audio and signalling operations handled by the integrated sub-audio signalling processor (selectable to CTCSS and DCS modes).

Other features include an auxiliary ADC channel, auxiliary DAC interface with optional RAMDAC to facilitate transmitter power ramping, auxiliary system clock output and transmit output for single-point-modulation.

The CMX138 is available in a low-power (3.0V to 3.6V), 28-pin (E1) TSSOP package.
