Asahi Kasei Microdevices AK4104
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.GENERAL DESCRIPTION
