Mode 1: Master Option
HSYNC
,
BLANK
, FIELD
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode the ADV7172/ADV7173 can generate horizontal SYNC and Odd/Even FIELD signals. A transition of the FIELD
input when
HSYNC
is low indicates a new frame, i.e., vertical retrace. The
BLANK
signal is optional. When the
BLANK
input is
disabled, the ADV7172/ADV7173 automatically blanks all normally blank lines as per CCIR-624. Pixel data is latched on the rising
clock edge following the timing signal transitions. Mode 1 is illustrated in Figure 27 (NTSC) and Figure 28 (PAL). Figure 29 illus-
trates the
HSYNC

BLANK
and FIELD for an odd-or-even field transition relative to the pixel data.
