Power Supply
PMVCM bit

(Addr:01H, D1)
(Addr:01H, D0)
PMPLL bit
MCKO pin
3. PLL Slave Mode (MCKI pin)
MCKO bit
<Example>
LRCK pin
MCKI pin
BICK pin
PDN pin
(1) After Power Up: PDN pin “L”
(2) DIF1-0, PLL3-0 and FS3-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0”
(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.
(6) The normal clock is output from MCKO after PLL is locked.
(7) The invalid frequency is output from MCKO during this period.
(8) BICK and LRCK clocks should be synchronized with MCKO clock.
“L” time of 150ns or more is needed to reset the AK4647.
VCOM should first be powered up before the other block operates.
PLL lock time is 40ms(max).
