Mode 2—Master Option
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7312 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 ADV7312 automatically blank all nor-
mally blank lines as per CCIR-624.
HSYNC
is output on
S_HSYNC
,
BLANK
on
S_BLANK
, and
VSYNC
on
S_VSYNC
.
