Audio Serial Interface Format
Eight serial data formats can be selected by the DIF2-0 bits as shown in Table 14 at the SLAVE pin “L”. If the SLAVE pin
is “H”, the AK4586 is fixed in the slave mode and two serial data format can be selected by the DIF0 bit. In all formats the
serial data is MSB-first, 2's compliment format. The SDTO is clocked out on the falling edge of BICK and the SDTI1-3
are latched on the rising edge of BICK. BICK outputs 64fs clock in Mode 0-5. Mode 6-7 are the slave mode, and BICK is
available up to 128fs at fs=48kHz. In the format equal or less than 20bit (mode 0-2), LSBs in sub-frame are truncated. In
mode 3-7, the last 4LSBs are auxiliary data (see Figure 11).
When the Parity Error or Biphase Error occurs in a sub-frame, the AK4586 continues to output the last normal sub-frame
data from SDTO repeatedly until the error is removed. When the Unlock Error occurs, the AK4586 outputs “0” from
SDTO.
Mode 4, 5, 6 and 7 in SDTI input formats can be used for 16-20bit data by zeroing the unused LSBs.
