SEBP11-8/2

PCI EXPRESS SERIAL SLOTS
The two x16 PCI Express slots on the SEBP11-8/2 backplane provide the mechanical connections between the PCI Express option cards and a PICMG 1.3 system host board. The slots mechanically support x16, x8, x4 and x1 PCI Express cards. The PCI Express electrical interfaces between the PCI Express slots A1 and B1 and the SHB are x8 PCI Express links. The actual PCI Express electrical configuration established between the SHB and an option card depends on both the SHB's PCI Express link configuration and the auto-negotiation/link training process that occurs between the specific PCI Express option card and the SHB.

PCI-X BUS SLOTS
Provides eight PCI Local Bus slots which support PCI Local Bus option cards; four of these PCI slots also support PCI-X option cards, which must be either +3.3V or universal option cards.

SHB SLOT
Accepts an SHB Express (PICMG® 1.3) compliant processor. Core's CEDX and CESX system host boards are examples of processors, SHBs or SBCs that are PCI Express compatible.

PCI EXPRESS-TO-DUAL PCI-X BRIDGES
The PCI Express-to-Dual PCI-X bridge eases the transition to PCI Express by supporting the PCI Local Bus as well as enabling 64-bit PCI-X architectures capable of running at speeds up to 66MHz. The bridge chip is fully compliant with the PCI-X Addendum to the PCI Local Bus Specifications Revision 1.0 and the PCI Local Bus Specification 2.2.

USB 2.0 INTERFACES
The SHB Express specification defines optional I/O routings from the SHB to the backplane. Core's SEBP11-8/2 supports two USB 2.0 headers capable of providing up to four USB 2.0 backplane ports.

PCI-TO-PCI BRIDGE
The PCI-to-PCI bridge supports the PCI Local Bus Specification 2.2. The SEBP11-8/2 backplane has bus mastering capabilities on the four PCI Local Bus Slots. These slots are +5V tolerant making them ideal for supporting legacy PCI option cards.

POWER CONNECTORS
The SEBP11-8/2 backplane is available with an ATX or EPS power connector.
The EPS configuration is recommended for use with system host boards such as Core's CEDX that use dual, high-performance Intel® Xeon™ processors. Either the ATX or EPS configurations can be used with dual, low voltage Intel® Xeon™ processors or single processor configurations.

AUXILIARY POWER CONNECTOR
A +12V power connector is also provided for routing auxiliary power to the SHB's edge connectors. This new capability of PICMG 1.3 compliant SHBs and backplanes eliminates the need for auxiliary power connections on the system host board.

EXTENDED-CURRENT TERMINAL BLOCKS
Extended-current terminal blocks provide additional power capacity for power-intensive applications -- up to 80 Amps of +12V, 80 Amps of +3.3V and 40 Amps of +5V.

ETHERNET INTERFACES
Core's SEBP11-8/2 backplane supports the optional Ethernet routing feature of the SHB Express specification. Two 10/100/1000Base-T Ethernet RJ-45 connectors are available for use on the backplane. Data communication performance of the backplane's Ethernet interfaces depends on the Ethernet controller hardware and configuration on the system host board. Consult your SHB Ethernet interface implementation method for details.

PRINTED CIRCUIT LAYERS
The backplane is a six-layer, .062" thick board with three separate signal layers: +5V, +3.3V and ground. Multi-layer backplane construction provides excellent noise immunity.

POWER INDICATORS
The power indicators provide a convenient visual check for +5V, -5V, +5V AUX,+12V, -12V and +3.3V power connections.
