What is SAI audio?
The Synchronous Audio Interface (SAI) module found in S32K148 device is targeted to be used in different applications in which audio processing is required. This module is highly-configurable and allows users to process audio in different audio format such as I2S, Codec/DSP and TDM.
What is SAI serial audio interface?
The Serial Audio Interface (SAI) implements a synchronous serial bus interface for connecting digital audio devices. It is by far the most common mechanism used to transfer two channels of audio data between devices within a system. SAI can transfer digital audio using various protocols: User Defined Protocol.
What is PCM interface?
PCM is another 4 wire interface, very similar to I2S, which can support a more flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used to synchronise the link while the Tx and Rx lines are used to transmit and receive the audio data.
What is PDM output?
Pulse-density modulation, or PDM, is a form of modulation used to represent an analog signal with a binary signal. The output of a 1-bit DAC is the same as the PDM encoding of the signal.
What does I2S stand for?
The Integrated Inter-IC Sound Bus (I2S) is a serial bus interface standard used for connecting digital audio devices together.
What is companding in PCM system?
For digital audio signals, companding is used in pulse code modulation (PCM). The process involves decreasing the number of bits used to record the strongest (loudest) signals. In the digital file format, companding improves the signal-to-noise ratio at reduced bit rates.
Is the I2S the same as the IIS?
“i2s” redirects here. It is not to be confused with IIS (disambiguation), IS2 (disambiguation), or I2 (disambiguation). I²S ( Inter-IC Sound, eye-squared-ess ), is an electrical serial bus interface standard used for connecting digital audio devices together.
What’s the difference between I2C and I2S in IC?
This page on I2C vs I2S describes basic difference between I2C and I2S. • I 2C stands for “inter-IC bus”. It is also used as I2C for simplicity. • I2C is a low speed and two wire serial data connection bus used in IC(Integrated Circuit).
Which is the correct spelling I²s or I2S?
The I²S bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that need to recover the clock from the data stream. Alternatively I²S is spelled I2S (pronounced eye-two-ess) or IIS (pronounced eye-eye-ess).
What does I²s stand for in audio equipment?
In audio equipment, I²S is sometimes used as an external link between a CD player and an external digital-to-analog converter, as opposed to a purely internal connection within one player box. This may form an alternative to the commonly used AES/EBU, Toslink or S/PDIF standards.
