The 3M High-Speed Card-Edge Connector SPD08 supports high-speed board-to-board and wire-to-board connections. It has a robust and flexible contact design for reliable connections. It also features a flexible stacking height and compact design to conserve board space and provide optimal value to customers. The connector’s flexible design handles from 20 up to 200 contact positions and can support up to 15 Gbps board-to-board applications. Additionally, when used in conjunction with the 3M™ Twin Axial Cable, the 3M SPD08 connector supports up to 25 Gbps wire-to-board applications with a reliable, simultaneous ribbon termination.
Market Segments and Applications
The SPD08 connector is typically used by enterprise & network OEMs whose applications include datacom systems, enterprise servers, test applications, defense, and telecommunications equipment. More specifically, this includes base stations, servers, hubs, switches, and routers. Within these markets, SPD08 supports multiple application protocols. These include the 10 Gigabit Attachment Unit Interface (XAUI), Peripheral Component Interconnect Express (PCIe) and the Serial Advanced Technology Attachment (SATA).
Features & Benefits
Supports High Speed Board-to-Board Connections
- - Controlled impedance, crosstalk limiting contact design supports speeds of up to 15 Gbps (at 30 mm stack height)
- - Embedded ground plane within riser card limits row-to-row crosstalk and enhances signal integrity
- - Supports XAUI, PCI express (Gen 1/2/3), SATA and other application speeds
Flexible Stacking Height and Robust Connection
- - Supports flexible stacking height (16–40 mm) with the use of a PCB intermediate riser card
- - Robust contact design is tolerant of misalignment, provides a reliable connection, and supports blind mate
High Density Board Footprint
- - High density (0.8 mm pitch), two-row design conserves board space and simplifies trace routing Flexible Design Options
- - 20–200 contact positions (see availability and standard configuration details in customer drawing 78-5100-2420-7)
- - Available with optional latches for robust mechanical stability
- - 0.5 A current rating per contact for mixed signal and power applications
Widespread Applicability
- - Supports 25 Gbps wire-to-board applications using 3M™ Twin Axial Cable terminated to the edge
Promise to the User
The SPD08 Connector features high-speed signal transmission performance up to 15 Gbps for board-to-board applications and 25 Gbps for wire-to-board applications. Its high density 0.80 mm pitch surface-mount structure features a flexible stacking height and a robust tolerance for misalignment, which is ideal for blind mate applications. Each single pin has a current-carrying capacity of up to 3.0 A, and the connector’s LCP resin housing can withstand 260 °C.
