I²S (Inter-IC Sound, pronounced "eye-squared-ess"), is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I²S bus separates clock and serial data signals, resulting in … Visa mer This standard was introduced in 1986 by Philips Semiconductor (now NXP Semiconductors) and was first revised June 5, 1996. The standard was last revised on February 17, 2024 and updated terms Visa mer The I²S protocol outlines one specific type of PCM digital audio communication with defined parameters outlined in the Philips specification. Visa mer • SPI bus • S/PDIF Visa mer 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 Visa mer • I²S Specification - Philips/NXP • I²S and STM32F4 Slides - Auburn University • Common inter-IC digital interfaces for audio data transfer, PDF Visa mer WebbThe clocks coming from CPU can only output one frequency clock perfect, resulting in major problems with audio files sampled at 44khz and multiple.
