Reclocking DAs help to compensate for jitter induced by long cable runs. Frequencies travel down a cable at different speeds, causing the shapes and spacing of pulses to create “perceived” jitter at the end of long cable runs (>50 meters). This reclocking DA reduces jitter sufficiently for all of the “far end” loads at a lower cost than an equalizing DA with three long, high quality cables.

Details:
This reclocking DA consists of areclockingcircuit, plus the equalizing function seen on the digital videoequalizing DA's. The output of the equalizer’s slicing circuit locks ahigh frequency VCO (Voltage Controlled Oscillator). The VCO output isused as a clock input to a flip-flop circuit which stores the state ofthe digital input wave form during each bit period. The process removesthe phase jitter that results from dispersion of the incoming cable andslicing errors in the equalizer circuit.
