Description
Pericom Semiconductor’s PI2PCIE412-D is an 8 to 4 differential
channel multiplexer/demultiplexer switch. This solution can
switch 2 full PCI Express lanes to one of two locations. Using
a unique design technique, Pericom has been able to minimize
the impedance of the switch such that the attenuation observed
through the switch is negligible. The unique design technique
also offers a layout targeted for PCI Express signals, which
minimizes the channel to channel skew as well as channel to
channel crosstalk as required by the PCI Express specification.
Application
Switch a PCI-Express lane output between two PCI Express lane
inputs.

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.
