Figure 109. SD Timing Mode 1, Slave Option, PAL
Mode 1—Master Option (Subaddress 0x8A = X X X X X 0 1 1)
In this mode, the ADV739x can generate horizontal synchronization and odd/even field signals. When HSYNC is low, a transition of the
field input indicates a new frame, that is, vertical retrace. The ADV739x automatically blanks all normally blank lines as required by the
CCIR-624 standard. Pixel data is latched on the rising clock edge following the timing signal transitions. HSYNC and FIELD are output
on the HSYNC and VSYNC pins, respectively.
Figure 110. SD Timing Mode 1, Odd/Even Field Transitions (Master/Slave)
Mode 2— Slave Option (Subaddress 0x8A = X X X X X 1 0 0)
In this mode, the ADV739x accepts horizontal and vertical synchronization 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 ADV739x automatically blanks all normally blank lines as required by the CCIR-624 standard. HSYNC and VSYNC are input on
the HSYNC and VSYNC pins, respectively.
