3M™ SPD08 High-Speed Card-Edge Connectors are board-to board connectors suitable for use in mezzanine board stacking designs requiring transmission of high-speed (up to 15 Gbps), high density, controlled impedance signals as well as wire-to-board designs requiring transmission of high speed signals (up to 25 Gbps). SPD08 features a high density 0.8mm pitch, two-row design to conserve board space and simplify trace routing. These connectors offer flexible stacking height (16-40 mm) with the use of a PCB intermediate riser card. The embedded ground plane with riser card limits row-to-row crosstalk and enhances signal integrity. SPD08 supports XAUI, PCI Express (Gen 1/2/3), SATA, and other application speeds.
