Product Summary
The Digital Audio Input/Output circuit (DAIO) of the TDA1315H/N2 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 TDA1315H/N2 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 TDA1315H/N2 multiplexes the audio control and user data and encodes it for subsequent transmission via a cable or optical link.
