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

The EL4583A 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.

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 EL4583A 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

and compensates for input levels of 0.5V to 2.0V

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.

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.
