General Description
The EL4583C extracts timing from video sync in NTSC PAL
and SECAM systems and non standard formats or from com-
puter graphics operating at higher scan rates Timing adjust-
ment is via an external resistor Input without valid vertical
interval (no serration pulses) produces a default vertical output
A larger package (16-pin) is used for greater flexibility The
‘‘core’’ pins match the same pin functions of the 8-pin
(EL4581C etc) for substitution in applications not requiring
these features
Outputs are
composite sync vertical sync filter burst
back porch horizontal no signal detect level and odd
even output (in interlaced scan formats only)
The EL4583C sync slice level is set to a mid-point halfway be-
tween sync tip and the blanking level This 50% point is deter-
mined by two internal sample and hold circuits that track sync
tip and back porch levels It provides hum and noise rejection
and compensates for input levels of 05V to 20Vp-p
A built in filter attenuates the chroma signal to prevent color
burst from disturbing the 50% sync slice Cut off frequency is
set by a resistor to ground from the
Filter Cut Off pin The
filter can be by-passed the video signal is fed to the
Video
Input
A DC voltage twice the sync amplitude from the
Level Out-
put pin drives AGC circuits A TTLCMOS compatible No
Signal Detect Output signals a loss or reduction in input sig-
nal level A resistor sets the
Set Detect Level
The EL4583C is manufactured using Elantec’s high perform-
ance analog CMOS process
