• Manufacturer Part Number: ak4633
• Description: 16-bit ?? Mono Codec With Alc & Mic/spk-amp
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
MS0447-E-03
Power Supply
(Addr:00H, D6)
(Addr:01H, D0)
PMVCM bit
PMPLL bit
4. EXT Slave Mode
<Example>
BICK pin
MCKI pin
FCK pin
PDN pin
(1) After Power Up: PDN pin “ L ” → “ H ”
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “ 0 ” → “ 1 ”
(4) Power down PLL: PMPLL bit = “ 0 ”
(5) Normal operation starts after the MCKI, FCK and BICK are supplied.
“ L ” time (1) of 150ns or more is needed to reset the AK4633.
VCOM should first be powered up before the other block operates.
