FN7173 Datasheet Sync Separator/ 50% Slice/ S-H/ Filter/ Horizontal sync output

Manufacturer: Intersil (now Renesas)

Overview

® EL4583 Data Sheet August 15, 2002 FN7173 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.
