Backplane System Integration

HDEC Series large format backplane supports one dual-processor HDEC Series SHB and up to fourteen PCI Express option cards.

All card slots are designed for the Gen3 PCIe electrical interface and are equipped with x16 PCIe mechanical connectors and I2C isolation.

Five of the HDB8259 backplane slots connected directly to the processors on the system host board.  Four of these slots feature PCI Express x16 PCIe electrical interfaces and the other direct-connect slot has a Gen3 PCIe x8 interface.

The backplane’s five remaining slots are driven by the SHB with a x8 electrical interface dynamically routed to each of the five slots via a 20-port PCIe Gen3 switch.

Customize the HDB8259 with our wide array of standard products to create a system that fits your specs and requirements.
