Function
Horizontal Sync Output
A reconstructed and phase-aligned version of the Hsync input. Both the polarity
and duration of this output can be programmed via serial bus registers. By
maintaining alignment with DATACK and Data, data timing with respect to
horizontal sync can always be determined.
Vertical Sync Output
A reconstructed and phase-aligned version of the video Vsync. The polarity of this
output can be controlled via a serial bus bit. The placement and duration in all
modes is set by the graphics transmitter.
Sync-On-Green Slicer Output
This pin outputs either the signal from the Sync-on-Green slicer comparator or an
unprocessed but delayed version of the Hsync input. See the Sync Processing
Block Diagram (Figure 12) to view how this pin is connected. (Note: Besides slicing
off SOG, the output from this pin gets no other additional processing on the
