PDN pin
(1) After Power Up: PDN pin “L”
(2) THR bit should be set to “1” and DIF1-0, FS3-0 and PLL3-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0”
(4) PLL starts after the PMPLL bit changes from “0” to “1” and PLL reference clock (EXLRCK or EXBCLK pin)
(5) Normal operation stats after that the PLL is locked.
is supplied. PLL lock time is 160ms(max) when EXLRCK is a PLL reference clock. PLL lock time is 2ms(max)
when EXBCLK is a PLL reference clock and the external circuit at VCOC pin is 10k+4.7nF
“L” time of 150ns or more is needed to reset the AK5701.
VCOM should first be powered up before the other block operates.
