Serial Data Interface
The AK4366 interfaces with external system via the SDATA, BICK and LRCK pins. In serial mode (P/S pin = “L”), five
data formats are available and are selected by setting DIF2, DIF1 and DIF0 bits (Table 3). In parallel mode (P/S pin =
“H”), two data formats are available and are selected by setting DIF0 pin (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.
