The phase relationship of the e
xter
nal HD and
VD should correspond to the center phase (i.e
., the e
xter
nal HD f
alling
edge) as illustr
ated in the abo
v
e
diag
ram.
External
VD falling edge:
Please input within about 200 cloc
k cycles of the standard center phase
.
Note that
V sync of the video is output with a dela
y of about 2H from the e
xter
nal
VD at the time of reset-restar
t and
the e
xter

igger mode
.
In the normal mode:
Continuously with the HD per
iod of 62.8 μs and
VD per
iod of 50.0 ms (par
tial scanning 25fps:
39.87 ms

Phase timing is as illustr
ated in the abo

In the reset-restar
t/e
xternal trig
g
er mode:
Contin
uously with the HD per
iod of 62.8 μs
. VD (reset) is at an arbitr
ar
y timing with the phase of HD being within the
standard of the abo
