GENERAL DESCRIPTION
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 in digital audio systems.
In the transmit mode, the device multiplexes the audio
control and user data and encodes it for subsequent
transmission via a cable or optical link.
