Example:
Audio I/F Format : DSP Mode, BCKP = MSBS = “0”
PLL Reference clock: BICK
BICK frequency: 64fs
Sampling Frequency: 8kHz

time (1) of 150ns or more is needed to reset the AK4632.
(2) DIF1-0, FS3-0, PLL3-0, MSBS and BCKP bits should be set during this period.
(3) Power Up VCOM: PMVCM bit =
“
0
”
→
“
1
”
VCOM should first be powered up before the other block operates.
(4) Pull down of the MCKI pin: MCKPD bit =
“
1
”
(5) PLL starts after the PMPLL bit changes from
“
0
”
to
“
1
”
and PLL reference clock (FCK or BICK pin) is supplied.
PLL lock time is 160ms(max) when FCK is a PLL reference clock. And PLL lock time is 2ms(max) when BICK
is a PLL reference clock.
(6) Normal operation stats after the PLL is locked.
