Video Input / Sync Detector
Either an AC-coupled video signal or a DC-coupled TTL-compatible composite
sync signal may be input via the VIDEO input pin (negative-going sync polarity).
When AC coupled, the clamping circuitry attempts to force the VIDEO pin voltage
during sync tips to VCC/2.
Command register_0 specifies the threshold above the sync tip to use for sync
detection. If the sync tip on VIDEO is below the selected threshold, composite
sync information is detected and output onto CSYNC* with no pipeline delay and
asynchronous to the pixel clock.
Typically, the VIDEO input will be connected to the TTL-compatible CSYNC*
output of the Bt252/254 Image Digitizer, and the highest sync slicing level will be
selected.
