Figure 78. 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 AK4645.
The AK4645 should be operated by the recommended power-up/down sequence shown in “System Design
(Grounding and Power Supply Decoupling)” to avoid the pop noise at line output and headphone output.
(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.
