Design Considerations
Intra-Pair Skew – The time difference
between the true and complementary signals
of a given differential pair should be kept as
small as possible.
Residual Jitter – The difference in the
amount of measured jitter between the test
point and the signal source. It is the allowable
maximum residual jitter is equivalent to the
minimum jitter budget between transmitter
and receiver.
ESD – External connectors being exposed
to the outside world are especially susceptible
to electrostatic discharge. A higher ESD
rating provides improved protection.
