TLV320AIC1109 Datasheet Pcm Codec

Manufacturer: Texas Instruments

Overview: TLV320AIC1109 PCM CODEC SLAS358 – DECEMBER 2001.

General Description

The PCM codec is designed to perform the transmit encoding analog/digital (A/D) conversion and receive decoding digital/analog (D/A) conversion, together with 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.

From a 2.048-MHz master clock input, the PCM codec generates its own internal clocks.

Key Features
