The purpose of this page is to describe the Linux ALSA SoC driver for SPDIF transmitter/receiver SoftIP.
Table of contents
The LogiCORE IP SPDIF/AES3 core is a digital audio interface controller that implements the PCM IEC 60958-3 interface features for transmitting and receiving audio data. The core can be configured as an SPDIF/AES3 audio data transmitter or an SPDIF/AES3 audio data receiver.
Typical System Using SPDIF Rx and Tx:
Following design depicts the typical SPDIF transmitter/receiver IP interfaces for audio playback and recording.In transmitter mode, audio from a source like file storage is fed to SPDIF IP block configured in transmitter mode via Audio Formatter. Similarly, in receiver mode, incoming SPDIF audio is fed to SPDIF IP configured as receiver then given to Audio Formatter IP and sent to DDR from which it can be saved to a file as PCM audio.
