AK4104
192kHz 24-Bit 3.3V DIT
GENERAL DESCRIPTION
The AK4104 is a digital audio interface transmitter (DIT) which supports data rate up to 192kHz sample rate
operation. The AK4104 encodes and transmits audio data according to the AES3, IEC60958, S/PDIF & EIAJ
CP1201 interface standards. The AK4104 accepts audio and digital data, which is then encoded. The audio
serial port supports four formats.
