General Description
The EL4583C extracts timing from video sync in NTSC, PAL, and
SECAM systems, and non standard formats, or from computer graph-
ics operating at higher scan rates. Timing adjustment is via an external
resistor. Input without valid vertical interval (no serration pulses) pro-
duces 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 EL4583C 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 2.0VP-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 resis-
tor 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 reduc-
tion in input signal level. A resistor sets the Set Detect Level.
The EL4583C is manufactured using Elantec’s high performance ana-
log CMOS process.
