Example
Audio I/F Format:MSB justified (ADC and DAC)
Input MCKI frequency: 1024fs
MCKI pin: CMOS Level
Sampling Frequency:8kHz

MCKI, BICK and FCK input
Figure 37. Clock Set Up Sequence (4)
<Example>
(1) After Power Up, PDN pin “L”
à
“H”
“L” time (1) of 150ns or more is needed to reset the AK4536.
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0”
à
“1”
VCOM should first be powered up before the other block operates.
(4) Release the pulled-down of the XTI pin: MCKPD bit = “1”
à
“0”
Power down PLL: PMPLL bit = “0”
When MCKI pin is input by AC coupling: PMXTL bit = “1”
When MCKI pin is input by CMOS Level: PMXTL bit = “0”
(5) After the MCKI, FCK and BICK are supplied, the normal operation of the block which a clock is necessary for
becomes possible
