Recommended Termination
Figure 4A is the recommended source termination for applications
where the driver and receiver will be on a separate PCBs. This
termination is the standard for PCI Express™ and HCSL output
types. All traces should be 50Ω impedance single-ended or 100Ω
differential.

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 series resistor (Rs) at the driver offers
flexibility and can help dampen unwanted reflections. The optional
resistor can range from 0Ω to 33Ω. All traces should be 50Ω
impedance single-ended or 100Ω differential.
