GS4882, GS4982 Video Sync
Separators with 50% Sync Slicing
FEATURES
DESCRIPTION
The GS4882 and GS4982 are precision sync separators for
extracting timing information from NTSC, PAL, and SECAM
video signals. The GS4882 generates noise immune and
temperature stable composite sync, vertical sync, back porch
and odd/even field signals. The GS4982 provides a horizontal
sync output for those applications requiring horizontal sync
extraction.
The GS4882 and GS4982 feature an internal color burst filter
for minimization of spurious timing information and the reduction
of external component count. The precision 50% sync slicing
feature embodied in the device provides for superior sync
extraction in the presence of noise and varying sync pulse
amplitudes. The high performance dual mode input clamp
aids in maintaining the accuracy of the internally derived 50%
sync slicing level to within ±5% as well in reducing system
start-up/recovery time. In addition, a missing pulse detector
enables the devices to quickly respond to impulse noise by
temporarily turning on a Nosync Recovery Current connected
to the dual mode input clamp. The input stage will operate with
input signal amplitudes ranging from +0.5 to +4.0V peak to
peak with a +5V supply voltage.
The GS4882 and GS4982 have robust signal detection and
output muting circuitry. Should valid video be removed from
the device input, the absence of video will be automatically
detected and all outputs muted to a logic high state after a
defined probation period. Upon the return of a valid video
signal, device outputs are enabled after receiving 8 lines of
video. An internal frequency to voltage converter also allows
the device to differentiate between valid and invalid input
signals by analyzing the horizontal scan rate of the input signal
and comparing it against the expected input signal scan rate.
The GS4882 and GS4982 are available in standard 8 pin PDIP
and SOIC packages, operate with a + 4.5 to +13.2 volt supply
voltage range and typically consume less than 6 mA of current
with a +5 V supply voltage.
