Recommended Termination
Figure 3A 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 Expressand HCSL output types.
All traces should be 50
impedance single-ended or
100
differential.
Figure 3A. Recommended Source Termination (where the driver and receiver will be on separate PCBs)
Figure 3B 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 0
to 33. All traces
should be 50
impedance single-ended or 100 differential.
