ADV7310_15 Datasheet, PDF (71/84 Pages) Analog Devices – Multiformat 216 MHz Video Encoder with Six NSV 12-Bit DACs

Mode 2—Master Option
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7310/ADV7311 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 ADV7310/ADV7311 automati-
cally blank all normally blank lines as per CCIR-624. HSYNC
is output on S_HSYNC , BLANK on S_BLANK, and VSYNC
on S_VSYNC.
