Subject: [SI-LIST] Differential signals - skew - and EMC
Hello,
In an ideal situation differential signals will have no skew through the
transmission path and (as I understand it)
the common-signal (emi) will be very low as a result. Given that EMC is
very system dependent - does any one have
a rule of thumb or anxiety(!) factor for how much is skew is tolerable
before becoming an emissions (regulatory)
Issue?
Thanks in advance.
