The CPU-110-20 is a high performance Single Board Computer (SBC) based on the 3U OpenVPX™ (VITA 65) form factor. Offered in both convection cooled and ruggedized conduction cooled variants, the CPU-110-20 will meet the needs of numerous commercial and military applications requiring maximum processing power, low power consumption, and small physical footprint.

The CPU-110-20 adheres to the OpenVPX™ standard for a 3U Payload Module Profile designated as MOD3-PAY-2F2T-16.2.5-4 or MOD3-PAY-2F2U-16.2.3-3. These profiles consist of a dual x4 Gen2 PCI Express Data Plane and either dual 1000BASE-T Gigabit Ethernet or dual 1000BASE-BX control planes. XMC Site I/O to VPX consists 12 dedicated differential pairs which follow the VITA 46.9 P2w11-X12d XMC I/O standard.

At the heart of the CPU-110-20 is an Intel® 3rd Generation Core™ I7 Ivy Bridge Quad Core Processor and Panther Point QM77 Platform Controller Hub (PCH). These two devices form the central processing backbone of the design. With a dual-channel memory controller integrated in the processor, the CPU-110-20 supports up to 8 GBytes of DDR3 SDRAM running at up to 1667 MHz. One of the processor’s x8 Gen2 PCI Express (PCIe) ports is connected to a PLX PEX8616 PCIe switch. The downstream ports of the switch then connect to the VPX backplane data plane. The processor’s second x8 Gen 2 PCIe port is connected to the XMC site per VITA42.3. The PEX8616 switch can support non-transparent operation on one of the downstream VPX ports, effectively making it a non-transparent upstream port.
