Mode 2: Slave Option
HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 0)
In this mode the ADV7172/ADV7173 accepts 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 ADV7172/ADV7173 automatically blanks all normally
blank lines as per CCIR-624. Mode 2 is illustrated in Figure 30 (NTSC) and Figure 31 (PAL).
