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.

FEATURES

? Transceiver for SPDIF and“IEC 958”encoded signals

? High sensitivity input for transformer-coupled links

? TTL-level input for optical links

? Built-in IEC input selector

? Built-in IEC feed-through function

? Automatic sample frequency (fs) detection

? System clock recovery from IEC input signal

? Low system clock drift when IEC input signal is removed

? Error detection and concealment

? PLL lock detection in transmit mode

? Serial audio interface conforms to I2S-bus format

? Auxiliary I2S-bus input for Analog-to-Digital Converter (ADC)

? Audio output selector

? Microcontroller-controlled and stand-alone mode

? 128-byte buffer for user data

? Bytewise exchange of user data with microcontroller
