STM32中的I2S(Inter-IC Sound)接口和SA接口(这里的SA可能指的是SAI,Serial Audio Interface)虽然都用于音频数据传输,但它们在设计目标、功能特性和应用场景上存在一些区别: I2S (Inter-IC Sound) 定义:I2S是一种专为数字音频设备间的通信而设计的串行接口标准,最初由飞利浦公司开发。它主要应用于音频编解码器、数...

I2S signals, shown in Figures 1 and 2, consist of a bit-clock, Left/Right Clock (also is often referred to as the Word Select) and alternating left and right channel data. This protocol can be compared to synchronous serial ports inTDM mode with 2 timeslots (or channels) ac...

Simplifying System Integration™ DS_1x22_001 DESCRIPTION The 73M1822 MicroDAA is the world's first single-package silicon Data Access Arrangement (DAA) for data/fax modem and voice applications. It provides a serial Modem Analog Front End (MAFE) interface to popular DSP/host processors ...
An external DSP can be used for adding extra sound processing features via the digital I/O-bus. The UDA1321 supports the standard I2S-bus data input format and the LSB-justified serial data input format with word lengths 16, 18 and 20 bits. The wide dynamic range of the bitstream ...
The word select clock lets the device know whether channel 1 or channel 2 is currently being sent, since IS allows two channels to be sent on the same data line. It is a 50% duty-cycle signal that has the same frequency as the sample frequency. For stereo material, the IS specification...
