BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7302A/ADV7303A can generate horizon-
tal 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 ADV7302A/ADV7303A
automatically blanks all normally blank lines as per CCIR-624.
HSYNC
is output on the
S_HSYNC
Pin,
BLANK
on the
S_BLANK
Pin, and FIELD on the
S_VSYNC
Pin.
