When changing MCLK frequency in master/slave mode, the AK5388 should reset by PDN pin = “L”. (ex.
12.288MHz(@fs=48kHz) at CKS1 pin = CKS0 pin = “L”.
■
12 different audio data interface formats can be selected using the TDM1-0, M/S and DIF pins as shown in
audio data format can be selected by the DIF pin. In all formats the serial data is MSB-first, 2's compliment format. The
SDTO1/2 is clocked out on the falling edge of BICK.
In normal mode, Mode 0-1 are the slave mode, and BICK is available up to 128fs at fs=48kHz. BICK outputs 64fs clock
in Mode 2-3.
In TDM256 mode, all of the ADC’s serial data (four channels) is output from the SDTO1 pins. The SDTO2 output is
fixed to “L”. BICK should be fixed to 256fs. In slave mode, “H” time and “L” time of LRCK should be at least 1/256fs. In
master mode, “H” time (“L” time at I
