• Manufacturer Part Number: ak8825
• Description: Hd/sd Multi Format Video Encoder With 3ch Dac
• Manufacturer: AKM Semiconductor, Inc.

■ Power Down
Power-Down Sequence and reset sequence after power-down release of AC Timing definition.
After releasing PDN-Pin =Low, all register values become default values, It is necessary to set the register again.
During PDN pin =Low, AVDD and DVDD can be power-off with PVDD1and PVDD2=ON.
■ Sleep Mode
this mode, all blocks except serial I/F block become power down mode. To save power consumption much less, use the
PDN-pin.
Sub Address 0x06
Rev-E-00
It is possible to make AK8825 power down states with PDN-pin = Low. Power down sequence is defined section (6)
To set SLPEN[1:0]-bit of Powerdown Mode Register (R/W) [Sub Address 0x06] =[11], AK8825 becomes sleep mode. In
