Inter-Integrated Circuit Sound (I²S, pronounced "eye-squared-ess" [citation needed]) is a serial interface protocol for transmitting two-channel, digital audio as pulse-code modulation (PCM) between integrated circuit (IC) components of an electronic device.

Standardized communication structures are vital for both the equipment and the IC manufacturer, because they increase system flexibility. To this end, we have developed the inter-IC sound (I2S) bus – a serial link especially for digital audio.

2025年1月20日 · I2S有三种，一种是飞利浦的标准I2S模式，另外两种分别是左对齐模式和右对齐模式。 所有模式都是MSB高位先行，并且发送的是二进制补码。

2024年6月4日 · I2S（Inter -IC Sound）是一种广泛应用于数字音频传输的串行接口标准。 它最初由飞利浦（Philips）公司开发，用于解决在 集成电路 之间传输音频数据的问题。 I2S协议定义了音频数据的传输格式、时序和控制信号。 在工作中音频采集和输出，AD和主芯片之间的通信均是通过I2S进行通信的，其应用场景如下： I2S RX方向：麦克风在机械振动下将声音信号转变为电压信号，电压信号经过放大等处理，给到ADC采样，将模拟信号转化为数字信号；音频在ADC …

2024年10月17日 · I2S全称Inter-IC Sound, Integrated Interchip Sound，或简写IIS，是在1986年定义（1996年修订）的数字音频传输标准，用于数字音频数据在传输，例如：CODEC、DSP、数字输入/输出接口、ADC、DAC和数字滤波器等。

Inter-Integrated Circuit Sound (I2S) is a communication protocol specifically designed for transporting digital audio signals. Developed by Philips Semiconductors (now NXP Semiconductors) in the 1980s, I2S is used primarily in consumer electronics to carry stereo audio data between devices such as processors and digital-to-analog converters (DACs).

2020年3月4日 · I2S was created in the 1980s, when digital was beginning its conquest of the consumer-audio market. The stated purpose of I2S is to facilitate the development of audio electronics by means of a standardized interface for transmission of digital data among ADCs, DACs, digital filters, digital signal processors, and other types of ICs used in ...

I2S (Inter-IC Sound) is a serial communication protocol designed for transferring digital audio data between integrated circuits. I2S is used for its high-quality audio transmission, precise synchronization, efficient data transfer, and compatibility in various devices, making it a preferred choice for digital audio communication.

2024年6月17日 · I2S is a widely used digital audio interface that provides a simple and efficient way to transmit high-quality audio data between devices. By understanding the I2S protocol, its configuration options, and implementation techniques, you can effectively integrate I2S into your audio projects and ensure seamless audio communication between components.

What is I2S Protocol? The protocol which is used to transmit digital audio data from one device to another device is known as I2S or Inter-IC Sound protocol. This protocol transmits PCM (pulse …
