Pericom Semiconductor’s PI2PCIE212 is a 4 to 2 differential
channel multiplexer/demultiplexer switch. The PI2PCIE family
of switch solutions is fully compliant with PCI-express signals
at 2.5Gbps. PI2PCIE212 can switch PCI-express signals up to
a maximum length of 16 inches. Due to its low bit-to-bit skew,
high channel-to-channel noise isolation and high bandwidth, this
product is ideal for PCI Express switching.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 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 on transition per measurement.
