Mode 3: Master/Slave Option
HSYNC
,
BLANK
, FIELD
(Timing Register 0 TR0 = X X X X X 1 1 0 or X X X X X 1 1 1)
In this mode, the ADV7304A/ADV7305A accepts or generates
horizontal SYNC and odd/even FIELD signals. A transition of
the FIELD input when
HSYNC
is high indicates a new frame,
i.e., vertical retrace. The
BLANK
signal is optional. When the
BLANK
input is disabled, the ADV7304A/ADV7305A automati-
cally blanks all normally blank lines as per CCIR-624.
HSYNC
is interfaced on the
S_HSYNC
pin,
BLANK
on the
S_BLANK
pin, and FIELD on the
S_VSYNC
pin.
