3.5.1. S/P DIF Audio
S/P DIF (Sony/Philips Digital Interconnect Format) is a type of digital audio interconnects cable used in
consumer audio equipment to output audio over reasonably short distances. The signal is transmitted
over either a coaxial cable with RCA connectors or a fibre optic cable with TOSLINK connectors. S/P DIF
is based on the professional AES3 interconnect standard. S/P DIF can carry two channels of PCM audio
or a multi-channel compressed surround sound format such as Dolby Digital or DTS.
The EDM1-IMX6PLUS features an S/P DIF interface allowing EDM module to transmit digital audio data.
The S/PDIF interface is implemented by means of the i.MX6 integrated S/P DIF transceiver.
For additional details, please refer to
“Sony/Philips Digital Interface (SPDIF)” Chapter of the “i.MX6
Reference Manual”.
