Functional Outline
Clock input pin.
Input a clock which is synchronized with data.
When to input 601 data : 27 MHz.
When to input square pixel data : 24.5454 MHz ( NTSC )/ 29.50 MHz ( PAL )
Internal clock is inverted (internal operation timing edge is inverted.)
Connect to either PVDD or PVSS(DGND).
Power Down Pin. After returning from PD mode to normal operation, RESET
Sequence should be done to AK8817.
“L “(GND level): Power-down
“H “: normal operation
Reset input pin. In order to initialize the device , an initialization must be made in
accordance with the reset sequence.
“L “ : reset
“H “ : normal operation
Hi-Z input is acceptable to this pin at PDN = L.
I2C data pin.
This pin is pulled-up to PVDD.
Hi-Z input is possible when PDN is at low.
SDA input is not accepted during the reset sequence operation.
I2C clock input pin
An input level of lower-than-PVDD should be input.
Hi-Z input is possible when PDN is at low.
SCL input is not accepted during the reset sequence operation.
Data Video Signal input pin (MSB).
Hi-Z input is acceptable to this pin at PDN = L.
