3.3V digital output. Buffered HSYNC (or SOG or CSYNC) output. This is typically used for measuring HSYNC
period. This output will pass composite sync signals and Macrovision signals if present on HSYNC
SOG
3.3V digital output. Buffered VSYNC output. For composite sync signals, this output will be asserted for the
duration of the disruption of the normal HSYNC pattern. This is typically used for measuring VSYNC period.
