FCK pin
PDN pin
(1) After Power Up: PDN pin “L” → “H”
(2) DIF1-0, PLL3-0, FS3-0, BCKO1-0, MSBS, BCKP and M/S bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0” → “1”
(4) Release the pull-down resistor of the MCKI pin: MCKPD bit = “1” → “0”
(5) Enable MCKO output: MCKO bit = “1”
(6) PLL starts after the PMPLL bit changes from “0” to “1” and PLL reference clock (MCKI pin) is supplied. PLL
(7) The normal clock is output from MCKO after PLL is locked.
(8) The invalid frequency is output from MCKO during this period.
(9) BICK and FCK clocks should be synchronized with MCKO clock.
lock time is 40ms(max).
“L” time (1) of 150ns or more is needed to reset the AK4632.
VCOM should first be powered up before the other block operates.
