(1) After Power Up, PDN pin = “L”

(3) Power UpVCOM: PMVCM bit = “0”
(4) In case of using MCKO output: MCKO bit = “1”
(5) PLL lock time is 40ms(max) after PMPLL bit changes from “0” to “1” and MCKI is supplied from an external
(6) The AK4643 starts to output the LRCK and BICK clocks after the PLL becomes stable. Then normal operation
(7) The invalid frequency is output from MCKO pin during this period if MCKO bit = “1”.
(8) The normal clock is output from MCKO pin after the PLL is locked if MCKO bit = “1”.
“L” time of 150ns or more is needed to reset the AK4647.
VCOM should first be powered-up before the other block operates.
In case of not using MCKO output: MCKO bit = “0”
