16-bit input mode
Vertical Sync. signal:
Horizontal Sync. signal:
Data input pin:
Input system clock frequency: fICLK = 12.2727272/13.5/14.31818/14.75 MHz
Clip level: None
IVS
IHS
YI[7:0], CI[7:0] (YCbCr-4:2:2)
* When the period of IVS is 625/2H or other than 525/2H (such as V that is separated from the ITU-R
BT.656 format), field detection is disabled so that operation cannot be guaranteed.
8-bit input mode
Vertical Sync. signal:
Horizontal Sync. signal:
Data input pin:
Input system clock frequency: fICLK = 24.545454/27/28.63636/29.5 MHz
Clip level: None

YI[7:0], (YCbCr-4:2:2)
* When the period of IVS is 625/2H or other than 525/2H (such as V that is separated from the ITU-R
BT.656 format), field detection is disabled so that operation cannot be guaranteed.
ITU-R BT.656 input mode
Vertical Sync. signal:
Horizontal Sync. signal:
Data input pin:
SAV, EAV split
SAV, EAV split
YI[7:0] (YCbCr-4:2:2)
Input system clock frequency: fICLK = 27 MHz
Clip level:
00h → 01h, FFh → FEh
* The ITU-R BT.656 input mode can be selected only for input of the interface format that complies with
ITU-R BT.656.
Synchronization operation as to ancillary data (ITU-R BT.1364) is only supported for a horizontal
blanking period between EAV and SAV. However, because the data is not written into memory, no data
will be output.
* For the format that does not comply with ITU-R BT.656, the operation is not guaranteed. However,
such format may be supported under the following setting.
- By setting POFF(SUB:41h-bit[6]) = 1, the parity bits of SAV and EAV can be disabled.
- By setting HBLKM(SUB:41h-bit[7]) = 1, the timing reference code (FF.00.00) can be disabled for 130
pixels following EAV.
