Description

Pericom Semiconductor’s PI3PCIE2215 is a 4 to 2 differential chan-

nel multiplexer/demultiplexer switch. The PI3PCIE family of switch

solutions is fully compliant with PCIe® signals at 5.0Gbps. 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.

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.
