Pixel Accurate Reclocking
Signal reclocking is an essential important procedure in digital signal transmission. After passing the
reclocking circuit, the signal becomes stable, jitter-free, and can be transmitted over more equipment like
reclocking. It removes not only intra-pair skew but inter-pair skew as well. The Pixel Accurate Reclocking
circuit eliminates the following errors:
Intra-pair skew
wire lengths or slightly different wire construction (impedance mismatch) in DVI cable. It results in jitter.
Inter-pair skew
Skew between two differential wire pairs in a cable. It is caused by different wire pair lengths or different
number of twists in the DVI cable. Too much inter-pair skew results color shift in the picture or sync loss.
Jitter
value, but noise and other effects cause variations.
Noise
Electromagnetic interference between other electronic devices such as mobile phones, motors, etc. and the
DVI cable are coupled onto the signal. Too much noise results in increased jitter.
