Introduction

The AK4103A is a digital audio transmitter (DIT) which supports data rate up to 192kHz sample rate operation. The AK4103A supports AES3, IEC60958, S/PDIF & EIAJ CP1201 interface standards. The AK4103A accepts audio data, auxiliary information data and etc, which is then biphase-encoded and driven on to a cable. The audio serial port supports eight formats. The AK4103A is a monolithic CMOS circuit that biphase-encodes and transmits audio data, auxiliary information data and etc according to the AES3, IEC60958, S/PDIF and EIAJ CP1201 interface standards. There is one set of stereo channels that can be transmitted simultaneously. The chip accepts audio data and auxiliary information data separately, biphase-mark encodes the data internally, and drives it directly or through a transformer to a transmission line. There are two modes of operation: asynchronous and synchronous.
