• Latched Mux Select
• Matched paths for all PCIe signals
• Low Crosstalk for high speed channels: [email protected] GHz
• Low Off Isolation for high speed channels: [email protected] GHz
• VDD Operating Range: 3.3V ± 10%
• ESD Tolerance: 8kV HBM on Display Port Path output
3kV HBM on PCI-Express path output
• Low channel-to-channel skew, 35ps max
• Packaging (Pb-free & Green):
– 56 TQFN (ZFE)
Description
Pericom Semiconductor’s PI3PCIE2612-A one to two Mux/
Demux is targeted for next generation systems that combine PCI-
Express gen-II signals with Display Port Signals.
Application
Routing DP and PCIExpress Gen1 or Gen2 signals with low signal
attenuation.

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.
