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.

■ Audio Interface Format
Data is shifted in via the SDTI pin using BICK and LRCK inputs. The DIF1-0 bits as shown in Table 2 can select four
serial data modes. In all modes the serial data is MSB-first, 2’s compliment format and is latched on the rising edge of
BICK. Mode 3 can be used for 16bit I2S Compatible format by zeroing the unused LSBs at BICK ≥ 48fs or BICK = 32fs.
