DESCRIPTION

The TLV320AIC1107 PCM codec is designed to

perform the transmit encoding analog-to-digital (A/D)

conversion, the receive decoding digital-to-analog

(D/A) conversion, and the transmit and receive filtering

for voice-band communications systems. The

TLV320AIC1107 device operates in either the 13-bit

linear or 8-bit companded (A-law) mode. The PCM

codec generates its own internal clocks from a

2.048-MHz master clock input.
