Description
The PI3PCIE3242A is a differential exchange switch featuring
pass-through pinout. It supports one full PCI Express® lane 2x2
Exchange Switch operating at 8.0Gbps PCIe® 3.0 performance.
With the select control input low, Port A connects to Port B, and
Port C connects to port D for an 8-channel differential pass-
though. When the select control input is high Port A connects to
Port D, and Port B connects to Port C.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Output 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
5. The outputs are measured one at a time with one transition per measurement.
