ADV7174/ADV7179
Mode 1: Master Option HSYNC, BLANK, FIELD
(Timing Register 0 TR0 = X X X X X 0 1 1)
Rev. A | Page 21 of 52
In this mode, the ADV7174/ADV7179 can generate 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 disabled, the ADV7174/ADV7179 automatically blanks all
normally blank lines as per CCIR-624. Pixel data is latched on
the rising clock edge following the timing signal transitions.
Mode 1 is illustrated in Figure 24 (NTSC) and Figure 25 (PAL).
Figure 26 illustrates the HSYNC, BLANK, and FIELD for an
odd or even field transition relative to the pixel data.
