Mode 2—Master Option
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7310/ADV7311 can generate horizontal
and vertical sync signals. A coincident low transition of both
HSYNC
and
VSYNC
inputs indicates the start of an odd field.
A
VSYNC
low transition when
HSYNC
is high indicates the
start of an even field. The
BLANK
signal is optional. When the
BLANK
input is disabled, the ADV7310/ADV7311 automati-
cally blank all normally blank lines as per CCIR-624.
HSYNC
is output on
S_HSYNC
,
BLANK
on
S_BLANK
, and
VSYNC
on
S_VSYNC
.
