Features
H
OUT
• NTSC, PAL, and SECAM sync separation
• Single supply, +5V operation
• Precision 50% slicing
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.
• Built-in programmable color burst filter
• Decodes non-standard vertical
• Horizontal sync output
Outputs are: composite sync, vertical sync, filter, burst/back
porch, horizontal, no signal detect, level, and odd/even
output (in interlaced scan formats only).
• Sync. pulse amplitude output
• Same socket can be used for 8 Ld EL4581
• Low-power CMOS
The EL4583 sync slice level is set to the mid-point between
sync tip and the blanking level. This 50% point is determined
by two internal sample and hold circuits that track sync tip
and back porch levels. It provides hum and noise rejection
• Detects loss of signal
• Resistor programmable scan rate
• Few external components
and compensates for input levels of 0.5V to 2.0V
.
P-P
• Available in 16 Ld PDIP and 16 Ld SO (0.150”) packages
• Pb-free plus anneal available (RoHS compliant)
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.
Additionally, the filter can be by-passed and video signal fed
directly to the Video Input.
Applications
• Video special effects
• Video test equipment
• Video distribution
• Multimedia
The level output pin provides a signal with twice the sync
amplitude which may be used to control an external AGC
function. A TTL/CMOS compatible No Signal Detect Output
flags a loss or reduction in input signal level. A resistor sets
the Set Detect Level.
• Displays
• Imaging
The EL4583 is manufactured using Intersil’s high
performance analog CMOS process.
• Video data capture
• Video triggers

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
