Express7-G3 Backplane

  1. 7 slot, Gen.3 PCI Express backplane
  2. Four x8 slots and three x16 slots
  3. 1x PICMG 1.3 SBC slot for host CPU
  4. 12V power connectors to support high power graphic cards
  5. Standard ATX form factor
  6. Support for multiple backplanes for large systems
  7. Temperature sensors monitored by Datapath Wall Monitor software
  8. 96 lanes PCI Express 3.0 switch
  9. Support for 2x SATA connections
  10. Provides headers for (1, 2 or 3) fans

The Datapath Express7-G3 backplane provides four x8 lane PCI Express 3.0 slots typically intended for hosting input cards, and three x16 lane PCI Express 3.0 slots targeted for hosting output cards.

The Express7-G3 can be used with a standard PICMG 1.3 single-board computer (SBC) as a stand-alone system or in combination with multiple backplanes to provide a PCI Express expansion system for a standard PC.

 

Connecting Multiple Express7-G3 Backplanes

Star Configuration

The four x8 PCI Express slots in the master chassis (containing the SBC) can be populated with an HLink-G3 card. Each HLink-G3 is then connected to an expansion chassis using an ExCable-G3 and SLink-G3 card. This configuration provides a high number of available PCI Express slots supporting low latency. The Express7-G3 can be used to connect a mixture of multiple Datapath Express7-G3, Express9 and Express9-G3, and Express11-G3 backplanes.

Daisy Chain Configuration

Expansion Link – HLink-G3, ExCable-G3 and SLink-G3

The SLink-G3 card can be used instead of a PICMG 1.3 SBC to configure the Express7-G3 as an expansion backplane from a standard PC or from other Datapath backplanes. The cards are available with Gen.3 compatibility, fully supporting the Datapath Express7-G3 backplane.
