EL4581 Overview
EL4581 Sync Separator, 50% Slice, S-H, Filter The EL4581 extracts timing information from standard negative going video sync found in NTSC, PAL and SECAM broadcast systems. It can also be used in non standard formats and with puter graphics systems at higher scan rates, by adjusting a single external resistor. When the input does not have correct serration pulses in the vertical interval, a default vertical output...
