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
and jaggies appear on the image.
only intra-pair skew but inter-pair skew as well. The Pixel Accurate
Reclocking circuit eliminates the following errors:
Intra-pair skew
Skew between the + and - wires within a differential wire pair (e.g.
Data2- and Data2+). It’s caused by different wire lengths or slightly
results in jitter.
-
Inter-pair skew
Skew between two differential wire pairs in a cable. It is caused by
cable. Too much inter-pair skew results color shift in the picture or
sync loss.

Jitter
Signal instability in the time domain. The time difference between two
cause variations.
-
Noise
Electromagnetic interference between other electronic devices such
signal. Too much noise results in increased jitter.
