(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7194 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 ADV7194 automatically blanks all normally blank lines as
per CCIR-624. Mode 2 is illustrated in Figure 45 (NTSC) and Figure 46 (PAL). Figure 47 illustrates the
HSYNC

and
VSYNC
for an even-to-odd field transition relative to the pixel data. Figure 48 illustrates the

an odd-to-even field transition relative to the pixel data.
