Figure 4A is the recommended source termination for
applications where the driver and receiver will be on separate
PCBs. This termination is the standard for PCI Express and
Figure 4B is the recommended termination for applications
where a point-to-point connection can be used. A point-to-point
connection contains both the driver and the receiver on the
same PCB. With a matched termination at the receiver,
transmission-line reflections will be minimized. In addition, a
