PI3PCIE3242 3.3V PCI Express® 3.0 4 Channel 2x2

PI3PCIE3242
3.3V PCI Express® 3.0 4 Channel 2x2 Exchange Switch
Features
Description
ÎÎ4 Differential Channel 2x2 Exchange Switch
Pericom semiconductor’s PI3PCIE3242 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.
ÎÎPCI Express® 3.0 performance, 8.0 Gbps
ÎÎBi-directional operation
ÎÎLow Bit-to-Bit Skew: 10ps (between ± signals)
ÎÎLow Crosstalk: -29dB @ 2.5GHz (5Gbps)
With the select control input low, Port A connects to Port B, and
Port C connects to port D for an 8-channel differential passthough. When the select control input is high Port A connects
to Port D, and Port B connects to Port C.
-20dB @ 4.0GHz (8Gbps)
ÎÎLow Insertion Loss: -1.1dB @ 2.5GHz (5Gbps)
-1.45dB @ 4.0GHz (8Gbps)
ÎÎVDD Operating Range: 3.3V ±10%
Truth Table
ÎÎESD Tolerance: 2kV HBM
ÎÎPackaging (Pb-free & Green):
àà 30-contact, TQFN (ZL30), 2.5 x 4.5mm.

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, t R ≤ 2.5ns, t F ≤ 2.5ns.
5.
The outputs are measured one at a time with one transition per measurement.
