REV. A
Mode 1: Master Option
HSYNC, BLANK, FIELD
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode the ADV7194 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
ADV7194 automatically blanks all normally blank lines as per CCIR-624. Pixel data is latched on the rising clock edge follow-
ing the timing signal transitions. Mode 1 is illustrated in Figure 42 (NTSC) and Figure 43 (PAL). Figure 44 illustrates the
HSYNC,
BLANK and FIELD for an odd-or-even eld transition relative to the pixel data.

Mode 2: Slave Option
HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 0)
In this mode the ADV7194 accepts 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 ADV7194 automatically blanks all normally blank lines as per
CCIR-624. Mode 2 is illustrated in Figure 45 (NTSC) and Figure 46 (PAL).
