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 select between high impedance or 75? termination of the input signal.
Backed by Link’s 10-year warranty, the DigiFlex 1143 is ready to provide years of error-free operation.
