Product Brief
Single Channel PCM / ADPCM Codec
CP1306
CP1306_PB_Rev1.0, March,2005
OVERVIEW
The CP1306 is a single channel PCM / ADPCM codec fabricated in advanced
low-power mixed-mode CMOS process. The CP1306 encodes the analog voice band
signal to 64 Kbps PCM (G.711) or 32 Kbps ADPCM (G.721) serial data, and decodes 64
Kbps PCM (G.711) or 32 Kbps ADPCM (G.721) serial data to analog voice band signal.
Its transmit/receive data mute, gain, side-tone attenuation, 12 dB loss PAD at receive
side and power down mode are programmable through a serial microcontroller interface.
