General Description
The EL4581C extracts timing information from standard nega-
tive going video sync found in NTSC PAL and SECAM broad-
cast systems It can also be used in non standard formats and
with computer graphics systems at higher scan rates by adjust-
ing a single external resistor When the input does not have
correct serration pulses in the vertical interval a default verti-
cal output is produced
Outputs are composite sync vertical sync burstback porch
output and oddeven output The later operates only in inter-
laced scan formats
The EL4581C provides a reliable method of determining correct
sync slide level by setting it to the mid-point between sync tip
and blanking level at the back porch This 50% level is deter-
mined by two internal self timing sample and hold circuits that
track sync tip and back porch levels This also provides a degree
of hum and noise rejection to the input signal and compensates
for varying input levels of 05 p-p to 20 Vp-p
A built in linear phase third order low pass filter attenuates
the chroma signal in color systems to prevent incorrectly set
color burst from disturbing the 50% sync slide
This device may be used to replace the industry standard
LM1881 offering improved performance and reduced power
consumption
The EL4581C video sync separator is manufactured using
Elantec’s high performance analog CMOS process
