6. SONY/PHILIPS DIGITAL
INTERFACE (S/PDIF)
The S/PDIF digital output is used to interface the
CS4201 to consumer audio equipment external to
the PC. This output provides an interface for stor-
ing digital audio data or playing digital audio data
to digital speakers. Figure 15 illustrates the circuits
necessary for implementing the IEC-958 optical or
consumer interface. For further information on
S/PDIF operation see application note AN22: Over-
view of Digital Audio Interface Data Structures [3].
For further information on S/PDIF recommended
transformers see application note AN134: AES and
S/PDIF Recommended Transformers [4].
