The IEC-754 Video Delay DA reflects the latest
state of the art inengineering. The IEC-754 is one
of the most versatile video delay DA's on the
market, and provides outstanding performance.
The delay is continuously variable from 30 nS to
475 nS.
The IEC-754 offers transparent transmission, with
-3dB frequency response to 32 MHZ, and -3dB to
16 MHZ with maximum delay. A differential input
is standard in the IEC-754, and provides more
than 80 dB of common mode rejection.
The versatility of the IEC-754 is illustrated by its
choiceofbuilt-infeatures. Aninternal spare32pin
IC socket provides for additional optional delay
that increases the delay by 200, 300, 400, or 500
nS. Cable equalization is adjustable from the front
panel with a calibrated control that compensates
for loss in coax cable for up to1000 feet of Belden
8281. A delay trim on the front panel allows
matchingofsignalpropagationdelayswitharange
of ±5ns. The IEC-754 is a notable addition to the
Link Electronics well recognized "700" series
products.
