NOTE:
In above waveforms, all timing is referenced to the
center
of the incoming Sync Pulse at Pin 1 or 3.
Above timings based on a 4.6
μ
s wide sync pulse.
Lower two levels of Sandcastle output alternate, based on video system in effect.
All timings are nominal, and apply to both PAL and NTSC signals.
