An information handling system includes a PCB, a transmitter for a data communication interface, a receiver for the data communication interface, a first channel instantiated in the printed circuit board, and a second channel instantiated in the printed circuit board. The receiver includes a first input and a second input. The first channel is coupled between an output of the transmitter and the first input of the receiver and is routed in a first path in the printed circuit board. The second channel is coupled to provide a reference voltage to the second input of the receiver and is routed in a second path in the printed circuit board. At least a portion of the second path is routed adjacent to a portion of the first path.

Noise cancellation in low-speed signals

A printed circuit board includes a dielectric and a connector. The dielectric has a first dielectric constant. A first area within the dielectric has a second dielectric constant. The connector is mounted on the dielectric. The connector includes a first connector lead mounted on the dielectric, a first contact point above the dielectric, and a first connector wipe. The first connector wipe is disposed above the first area.

Signal speed increase in a connector wipe

In one or more embodiments, a printed circuit board (PCB) may be configured for reduced insertion loss between traces. Two traces on different layers may be connected by two vias and two connector traces on different layers, wherein one connector trace may have a first length and a second connector trace may have a second length that is longer than the first length such that a first portion of a signal transmitted along a first signal path through the first connector trace arrives at the second trace at substantially the same time as a second portion of the sign transmitted along a second signal path through the second connector trace.
