Figure 87. Clock Set Up Sequence (3)
<Example>
(1) After Power Up: The PDN pin “L”
“H”. “L” time of 150ns or more is needed to reset the AK4673.
The AK4673 should be operated by the recommended power-up/down sequence shown in “System Design
(Grounding and Power Supply Decoupling)” to avoid pop noise at line output and headphone output.
(2) DIF1-0, PLL3-0 and FS3-0 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) Enable MCKO output: MCKO bit = “1”
(5) PLL starts after that the PMPLL bit changes from “0” to “1” and PLL reference clock (MCKI pin) is supplied.
PLL lock time is 40ms(max).
(6) The invalid frequency is output from MCKO during this period.
(7) The normal clock is output from MCKO after PLL is locked.
(8) BICK and LRCK clocks should be synchronized with MCKO clock.
