Serial Data Interface
The AK4367 interfaces with external system via the SDATA, BICK and LRCK pins. Five data formats are available and
are selected by setting DIF2, DIF1 and DIF0 bits (Table 3). Mode 0 is compatible with existing 16bit DACs and digital
filters. Mode 1 is a 20bit version of Mode 0. Mode 4 is a 24bit version of Mode 0. Mode 2 is similar to AKM ADCs and
many DSP serial ports. Mode 3 is compatible with the I
2
S serial data protocol. In Modes 2 and 3 with BICK
≥
48fs, the
following formats are also valid: 16-bit data followed by eight zeros (17th to 24th bits) and 20-bit data followed by four
zeros (21st to 24th bits). In all modes, the serial data is MSB first and 2’s complement format.
