EL4583 Sync Separator, 50% Slice, S-H, Filter, HOUT The EL4583 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 s
