DESCRIPTION

The PCM codec is designed to perform transmit

encoding analog/digital (A/D) conversion, receive

decoding digital/analog (D/A) conversion, and transmit

and receive filtering for voice-band communications

systems. The device operates in either the 15-bit linear

or 8-bit companded (μ-law or A-Law) mode, which is

selectable through the I2C interface. The PCM codec

generates its own internal clocks from a 2.048-MHz

master clock input.
