ADV7174/ADV7179
Mode 2: Master Option HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
Rev. A | Page 23 of 52
In this mode, the ADV7174/ADV7179 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 ADV7174/ADV7179 automatically
blanks all normally blank lines as per CCIR-624. Mode 2 is
illustrated in Figure 27 (NTSC) and Figure 28 (PAL). Figure 29
illustrates the HSYNC, BLANK, and VSYNC for an even-to-odd
field transition relative to the pixel data. Figure 30 illustrates the
HSYNC, BLANK, and VSYNC for an odd-to-even field
transition relative to the pixel data.
