Inter-Integrated Circuit Sound ( I²S , pronounced "eye-squared-ess") 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. An 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). Despite a similar name, I²S is unrelated to I²C .
