PCIe Gen 4 and Gen 5 Value Proposition PCIe Gen 4 and Gen 5 connectors meet industry standard PCIe 4.0 & 5.0 (Proposed) requiring higher speed performance. The optimized series supports backwards mating and is footprint compatible with PCIe 3/2/1. These 1.00mm pitch, vertical card edge connectors enable all generations of PCI Express signaling in desktop PCs, workstations, and servers. The connector designs provide support for 2.5Gb/s (Gen1), 5.0Gb/s (Gen2), 8.0Gb/s (Gen3) and recently upgrade to 16Gb/s (Gen 4), even further to 32Gb/s per differential signal pair. The base connector family provides x1, x4, x8, or x16 link widths to suit different bandwidth requirements. The basic bandwidth (x1) version supports a single PCI Express lane and is typically used for I/O cards in desktop PCs. The x4 and x8 connectors provide 64 and 98 contacts, respectively, for server I/O. The high bandwidth versions (x16 lanes and higher) are used for applications that require even more bandwidth, such as graphics cards in desktop PCs or riser cards in servers. Amphenol s expansive range of vertical PCIe Gen 4 and Gen 5 connectors will include options for surface mount (SMT), through hole solder, press-fit (PF) and straddle mount terminations. Page 3
PCIe Gen 4 and Gen 5 Product Overview Extending differential signaling to 16Gb/s and 32Gb/s for next generation systems PCIe connector meets Gen 4 and Gen 5 high speed performance Footprint backward compatible with Gen 3/2/1 (Straddle mount excepted) 85ohms reference impedance Data rate: 16 GT/s, up to 32GT/s. Product configuration includes x1, x4, x8,x16 (36/64/98/164), will extend to X24, X32 for riser card in future. PCB module expectation: Golden finger(add-in card): Pad dim (Gen 4) =0.70x3.91mm; Pad dim (Gen 5) =0.60x3.00mm (Proposed); Thickness=1.57±0.13mm Reference to Gen 3 electrical, mechanical and environment spec Halogen-Free complaint Amphenol Vertical PCIe Gen4 & Gen 5 Project timeline SMT Gen 4 & Gen 5 -Tooled up now TH Gen 4 Be ready by Dec 2017 PF Gen 4 Be ready by Jan 2018 Straddle mount Gen 4 Tooled up now Page 4
