Example:
Audio I/F Format: DSP Mode, BCKP = MSBS = “0”
BICK frequency at Master Mode: 64fs
Input Master Clock Select at PLL Mode: 13.5MHz
MCKO : Enable
Sampling Frequency:16kHz
(1) Power Supply & PDN pin = “L”

(3)Addr:00H, Data:40H
(2)Addr:04H, Data:C8H
Addr:05H, Data:02H
(4)Addr:01H, Data:03H

time (1) of 150ns or more is needed to reset the AK4633.
(2) DIF1-0, PLL3-0, FS3-0, BCKO1-0, MSBS, BCKP and M/S 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) PLL Power Up: PMVCM bit
“0”
→
“1”
(5) PLL lock time is 40ms(max) after the PMPLL bit changes from
“
0
”
to
“
1
”
and PLL reference clock (MCKI pin)
is supplied..
(6) The normal clock is output from MCKO after PLL is locked.
(7) The invalid frequency is output from MCKO during this period.
(8) BICK and FCK clocks should be synchronized with MCKO clock.
