I2S (Inter-IC Sound) is a serial bus (path) design for digital audio devices and technologies such as compact disc (CD) players, digital sound processors, and digital TV (DTV) sound. The I2S design handles audio data separately from clock signals. By separating the data and clock signals, time-related errors that cause jitter do not occur, thereby eliminating the need for anti-jitter devices. An I2S bus design consists of three serial bus lines: a line with two time-division multiplexing (TDM) data channels, a word select line, and a clock line.
