3.3V digital output. HSYNC output aligned with pixel data. Use this output to frame the digital output data.
This output is always purely horizontal sync (without any composite sync signals)
3.3V digital output.Artificial VSYNC output aligned with pixel data. VSYNC is generated 8 pixel clocks after
the trailing edge of HS
3.3V digital output. Buffered HSYNC (or SOG or CSYNC) output. This is typically used to measure HSYNC
period. HS
and Macrovision signals if present on HSYNC
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 to detect the beginning of a
frame and measure the VSYNC period.
Power supply for the analog section. Connect to a 3.3V supply and bypass each pin to GND
