TDA1315H - Digital audio input/output circuit DAIO

General Description

TDA1315H The Digital Audio Input/Output circuit (DAIO) of the TDA1315H is a complete transceiver for biphase-mark encoded digital audio signals that conform to the SPDIF and “IEC 958” interface standards (consumer mode), made in the full CMOS-process C200.

In the receive mode, the device adjusts automatically to one of the three standardized sample frequencies (32, 44.1 or 48 kHz), decodes the input signal and separates audio and control data.

A clock signal of either 256 or 384 times the sample frequency is generated to serve as a master clock signal
