Figure 81. Clock Set Up Sequence (4)
<Example>
(1) After Power Up: PDN pin “L”
“H”
“L” time of 150ns or more is needed to reset the AK4643.
(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) Normal operation starts after the MCKI, LRCK and BICK are supplied.
