VPX705

A VPX CPU board is a rugged plug-in computer board that provides the main processing capability in a VPX chassis.

It typically contains:

• A processor, such as Intel, AMD, Arm, or Power Architecture
• RAM
• Flash or SSD storage
• Ethernet and PCI Express interfaces
• Management and monitoring circuitry
• Front-panel ports for USB, serial, display, or networking
• VPX backplane connections for communicating with FPGA, GPU, storage, and I/O boards

VPX CPU boards are often designed for demanding environments and may support:

• Conduction or air cooling
• Extended temperatures
• High shock and vibration resistance
• Redundant operation
• Real-time operating systems
• Safety- or mission-critical applications

Common uses include radar, avionics, electronic warfare, military vehicles, industrial control, and high-performance embedded computing.

Description:

VPX705 is a Layerscape Processor in 3U form factor based on the NXP LX2160A (16-core) processor. The Module provides on P1 connector on ports 0-7 x8 PCIe Gen3 or dual x4 PCIe Gen3 on ports 0-7.  Further on the P1 connector the module has eight reconfigurable SERDES that are routed to ports 8-15. Below are some examples of the SERDES configuration:

• Dual PCIe x4 Gen3
• x4 GbE with PCIe x4 Gen3
• x4 10GBASE-KR with PCIe x4 Gen3
• x8 GbE
• PCIe Gen3 x4 with x4 10GBASE-KR
• x4 10GBASE-KR with x4 GbE
• x8 10GBASE-KR
• PCIe x4 Gen3 with PCIe x2 Gen3 with 2x GbE
• Dual 40GBASE-KR4

The module includes 32 GB of DDR4 memory with ECC, SDHC Socket, 64 MB SPI flash, 512 KB I2C flash, 8 GB of eMMC and 1TB NVMe storage.

The VPX705 can host an XMC module which interfaces to the host processor thru PCIe x4 Gen3. The XMC I/Os are routed to the backplane per VITA 46.9 as P2W4-X12s+X8d+X12d. The module also routes RS-232 from management, dual RS-232 and dual RS-422 from host, a USB 3.0/2.0 and a dual GPIO I/O’s (+5V) to P2. The RS485/RS422 termination and slew rates are software configurable.

The VPX705 routes the two VPX backplane clocks to the GPIO of the Processor.

The CPU has Secure Boot capabilities form power-on and hard reset.

This unit is also available for rugged conduction-cooled applications, see ordering options.
