(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7177/ADV7178 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 ADV7177/ADV7178 automatically blanks
all normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 21 (NTSC) and Figure 22 (PAL). Figure 23 illus-
trates the
HSYNC

BLANK
and
VSYNC
for an even-to-odd field transition relative to the pixel data. Figure 24 illustrates the
HSYNC
,
BLANK
and
VSYNC
for an odd-to-even field transition relative to the pixel data.
