ADV7172/ADV7173
Mode 1: Slave Option HSYNC, BLANK, FIELD
(Timing Register 0 TR0 = X X X X X 0 1 0)
In this mode the ADV7172/ADV7173 accepts horizontal SYNC and Odd/ Even FIELD signals. A transition of the FIELD input
when HSYNC is low indicates a new frame, i.e., Vertical Retrace. The BLANK signal is optional. When the BLANK input is dis-
abled, the ADV7172/ADV7173 automatically blanks all normally blank lines as per CCIR-624. Mode 1 is illustrated in Figure 27
(NTSC) and Figure 28 (PAL).
