DIFFERENTIAL CLOCK DATA MULTIPLEXER

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 50

Ω 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 0

Ω to 33Ω. All traces should be 50Ω

impedance single-ended or 100

Ω differential.
