Description

The AK4101A is a four outputs digital audio transmitter (DIT) which supports data rate up to 192kHz sample rate operation. It  supports AES3, IEC60958, S/PDIF & EIAJ CP1201 interface standards. The product accepts audio data and auxiliary information data and etc, which is then biphase-encoded and driven on to a cable. The audio serial port supports eight formats.
