Preliminary Technical Data
MODE 2—MASTER OPTION
(TIMING REGISTER 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7322 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 ADV7322 automatically blanks all
normally blank lines as per CCIR-624. HSYNC is output on
S_HSYNC , BLANK on S_BLANK , and VSYNC on S_VSYNC .
