The Pixel Accurate Reclocking circuit eliminates the following errors:
Intra-pair skew: skew between the + and - wires within a differential wire pair (e.g.
Inter-pair skew: skew between two differential wire pairs in a cable. It's caused by
Jitter:
Noise:
The Pixel Accurate Reclocking circuit completely regenerates the original video signal
and outputs a strong, high-quality digital signal that conforms to the DVI specification.
Section 4. Technologies
Data2- and Data2+). It's caused by different wire lengths or slightly
different wire construction (impedance mismatch) in DVI cable. It results
in jitter.
different wire pair lengths or different number of twists in the DVI cable.
Too much inter-pair skew results in color shift in the picture or sync
loss.
signal instability in the time domain. The time difference between two
signal transitions should be a fix value, but noise and other effects
cause variations.
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.
