Digital Voice Interface ICs

CML Micro Digital Voice Interface ICs comprise a range of flexible technologies supporting voice-data generation, coding, transcoding, and decoding functions for digital communication systems, as well as many other in-band audio applications where there is a need for storage and playback. These surface mount devices operate within a -40°C to +85°C temperature range and provide Serial, SPI, PCM, and I2S interface options.
