External HD
The phase relationship of the external HD and VD should correspond to the center phase (i.e., the external HD fall-
ing edge) as illustrated in the above diagram.
External VD falling edge:
Please input within about 100 clock cycles of the standard center phase.
Note that V sync of the video is output with a delay of about 2H from the external VD at the time of reset-restart
and the external trigger mode.
Other than for reset-restart or external trigger mode:
Continuously with the HD cycle (NORMAL: 13.74 μs / FAST: 11.31 μs).
Continuously with the VD cycle (NORMAL: 8.05 ms / FAST: 6.63 ms) (partial scanning is NORMAL: (72.794 kHz ×
1000) / (ROIVW + 42H) FAST: (88.393 kHz × 1000) / (ROIVW + 42H)).
Phase timing shown in above diagram (with only the falling edge applicable).
At reset-restart:
Continuously with the HD cycle (NORMAL: 13.74 μs / FAST: 11.31 μs).
VD (reset) is at an arbitrary timing with the phase of HD being within the standard of the above diagram.
In external trigger mode:
Continuously with the HD cycle (NORMAL: 13.74 μs / FAST: 11.31 μs).
The presence of VD is ignored.
