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%
