Sync Separator, 50% Slice, S-H, Filter

Features

The EL4581 extracts timing

information from standard negative

going video sync found in NTSC, PAL

• NTSC, PAL and SECAM sync separation

• Single supply, +5V

• Precision 50% slicing, internal caps

• Built-in color burst filter

and SECAM broadcast systems. It can also be used in non

standard formats and with computer 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 is produced.

• Decodes non-standard verticals

• Pin compatible with LM1881

• Low power

Outputs are composite sync, vertical sync, burst/back porch

output, and odd/even output. The later operates only in

interlaced scan formats.

• Typically 1.5mA supply current

• Resistor programmable scan rate

• Few external components

The EL4581 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 determined 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

• Available in 8 Ld PDIP and SOIC packages

• Pb-free available (RoHS compliant)

Applications

• Video special effects

• Video test equipment

• Video distribution

• Displays

signal, and compensates for varying input levels of 0.5V

P-P

to 2.0V

P-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.

• Imaging

• Video data capture

• Video triggers

The EL4581 video sync separator is manufactured using

Elantec’s high performance analog CMOS process.

NOTE: These Intersil Pb-free plastic packaged products employ special

Pb-free material sets; molding compounds/die attach materials and 100%

matte tin plate PLUS ANNEAL - e3 termination finish, which is 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.

Demo Board

A dedicated demo board is not available. However, this

device can be placed on the EL4584/5 Demo Board.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
