Figure 50. Clock Set Up Sequence (4)
<Example>
(1)After Power Up: PDN pin “L”  “H”
“L” time (1) of 150ns or more is needed to reset the AK4633.
(2)DIF1-0 and FS1-0 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)Power down PLL: PMPLL bit = “0”
(5)Normal operation starts after the MCKI, FCK and BICK are supplied.
