EL4583A Sync Separator, 50% Slice, S-H, Filter, HOUT The EL4583A extracts timing from video sync in NTSC, PAL, and SECAM systems, and non-standard formats, or from computer graphics operating at higher scan rates.
Timing adjustment is via an external resistor.
Input without valid vertical interval (no serration pulses) produces a default vertical output.
Outputs are: composite sync, vertical sync, filter, burst/back porch, horizontal, no signal detect, level, and odd/even output (in interlaced
