ADV7320/ADV7321
MODE 2—MASTER OPTION
(TIMING REGISTER 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7320/ADV7321 can generate horizontal
and vertical sync signals. A coincident low transition of both
HSYNC and VSYNC inputs indicates the start of an odd field.
Rev. 0 | Page 79 of 88
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 ADV7320/ADV7321
automatically blank all normally blank lines as per CCIR-624.
HSYNC, BLANK, and VSYNC are output on S_HSYNC,
S_BLANK, and S_VSYNC, respectively.
