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.
