PCI Express Mid-Bus Probe for Summit Analyzers

Version 1.1

25

5.2.3 Reference Clock Cable

The Reference Clock Cable (PE014UCA-X) connects the Mid-Bus Pod to the DUT so that the pod can
use the clock from the DUT. The cable has a 3-pin micro socket at one end that attaches to a 3-pin
header (0.050” spacing) designed into the DUT, and the other end connects to the

Clk In

port on the Mid-

Bus Probe Pod.

5.2.4 Daisy Chain Cable

The Daisy Chain Cable (PE009UCA-X) connects multiple Mid-Bus Pods together so they can share the
same clock. One end of the connector is attached to the

Clk Out

port of the Mid-Bus Pod supplying the

clock signal, and the other end is connected to the

Clk In

port of the other Mid-Bus Pod.
