A product Line of Pb Diodes Incorporated Lead-free Green PI3PCIE3442A 3.3V PCI Express 3.0 2-Lane Exchange Switch Features Description 8 Differential Channel (2-lane) Exchange Diodes PI3PCIE3442A is a differential exchange switch featur - ing pass-through pinout. It supports two full PCI Express lanes PCI Express 3.0 performance, 8.0 Gbps operating at 8.0Gbps PCIe 3.0 performance. Bi-directional operation With the select control input low, Port A connects to Port B, and Low Bit-to-Bit Skew: 10ps (between signals) Port C connects to port D for an 8-channel differential pass- Low Crosstalk: -29dB 2.5GHz (5Gbps) though. When the select control input is high Port A connects to -20dB 4.0GHz (8Gbps) Port D, and Port B connects to Port C. Low Insertion Loss: -1.1dB 2.5GHz (5Gbps) -1.45dB 4.0GHz (8Gbps) V Operating Range: 3.3V 10% DD o o Industrial Temperature Range: -40 C to 85 C Block Diagram ESD Tolerance: 2kV HBM Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) OE Halogen and Antimony Free.
