9.4 IEC 60958 Interface
The IEC 60958 interface is a digital audio interface that uses bi-phase coding to minimize the DC content of
the transmitted signal and allows the receiver to decode the clock information from the transmitted signal. The
IEC 60958 specification is based on the 2 industry standards:
 AES/EBU
 Sony and Philips interface specification SPDIF
The interface is compatible with IEC 60958-1, IEC 60958-3 and IEC 60958-4.
The SPDIF interface signals are SPDIF_IN and SPDIF_OUT and are shared no the PCM interface pins. The
input and output stages of the SPDIF pins can interface to:
 75Ω coaxial cable with an RCA connector, see Figure 25
 An optical link that uses Toslink optical components
