Samuel Conner
gives a talk

Room C1:04 start 16:00
Differential Signaling Is the Opiate of the Masses
A large concern with the proliferation of differential signalling is the false
sense of security that comes along with its usage. Differential signals are
hailed for their immunity to noise coupling and for their propagation
characteristics. Differential receivers have great common mode rejection, and
with equalization, receivers can pull meaningful signals out of a closed eye
diagram. But with all of these benefits, the often forgotten drawback is that
differential signals on PCBs are not truly differential and they do not
perfectly cancel. The various asymmetries in the routing of the differential
pair and the impedance discontinuities of vias and connectors and the imbalance
and skew of the drivers all create a common mode signal on the differential
pair that can cause serious EMC problems when coupled to other nets or radiated
from cables and connectors.
