Peripheral Audio[edit | edit source]
The Audio interface available on MITO 8M is based on iMX8M SoC which provides the following audio subsystems:
- Synchronous Audio Interface (SAI)
- 6x I2S/SAI (20+ channels, each 32-bits @384 kHz)
- Highest levels of pro audio fidelity with more than 20 audio channels each @384KHz
- Sony/Philips Digital Interface (SPDIF)
- S/PDIF Tx/Rx
Description[edit | edit source]
The I2S (or I2S) module provides a synchronous audio interface (SAI) that supports full- duplex serial interfaces with frame synchronization such as I2S, AC97, TDM, and codec/DSP interfaces. It supports the following standards and features:
- Transmitter and receiver with independent bit clock and frame sync supporting 8 data lines
- Each data line can support a maximum Frame size of 32 words
- Asynchronous 128 x 32-bit FIFO for each transmit and receive data line
- Supports packing of 8-bit and 16-bit data into each 32-bit FIFO word
- Supports combining multiple data line FIFOs into single data line FIFO
The Sony/Philips Digital Interface (SPDIF) audio block is a stereo transceiver that allows the processor to receive and transmit digital audio.
