The DigiFlex 1143 is a regenerative pulse
distribution amplifier designed to operate in the
DigiFlex 1000 or 7200 frame. Its input is
connected through a companion rear cell, Model
1011. The input pulse is re-sliced at the 50% point
by a level-tracking comparator circuit. Regardless
of the input level, it always slices at the 50% point.
The output width is constant, based on the input
signal at the 50% point. Overshoot and ringing are
eliminated due to this process.
Discrete linear amplifiers are used in the output
drivers to insure that pulse shape and rise/fall
times are accurately set by LC filter circuits. The
outputs are therefore fixed at 4.0Vpp with 140ns
rise/fall times and pulse width equal to the input
width at the 50% point. No internal adjustment or
calibration is required. A jumper is incorporated to
selectbetweenhighimpedanceor75Ω termination
of the input signal.
Backed by Link’s 10-year warranty, the DigiFlex 1143 is ready to provide years of error-free operation.
