Digital Audio Interface
The CS8416 is a monolithic complementary metal oxide semiconductor
(CMOS) device which receives and decodes one of eight channels of audio
data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface
standards. The CS8416 receives data from a transmission line, recovers
the clock and synchronization signals, and de-multiplexes the audio and
digital data.
The CS8416 is attached to the DAI port of the processor. The configura-
tion registers of the S/PDIF receiver are programmed via an SPI, which is
connected to the processor's SPI. The S/PDIF receiver is capable of trans-
mitting a variety of data formats, which are set up via the SPI interface.
