The VPX105 is a carrier module (VITA 46) for general purpose XMC/PMC that integrates I/O or processing COTS XMC/PMC modules into a VPX data processing system.

The onboard PCIe Gen3 switch supports XMC high bandwidth data throughput. The module routes 16 lanes of PCIe Gen3 to both P1 and P2, or either one of them, by ordering option. The configuration allows routing and segregation of the XMC/PMCs by configuring the switch to dual Virtual PCIe domain or to single PCIe domain. This configuration is done once by the user, to setup PCIe virtual domains for multi-root-complex system architectures, and is persistent across system boot.  Each backplane x16 lane is configurable by software to dual x8 or quad x4 lanes (or any other combination such as single x8 plus dual x4). 

The PMC sites with onboard PCI-X to PCIe bridge supports 64-bit PCI-X @133 MHz. J4 I/O signals are routed to the P3/P4 or P5/P6 connectors per VITA 46.9.

The XMC site can be supplied with VITA 42.0 or VITA 61.0 interface connectors.

The J14/J16 connectors of the XMC are routed per VITA 46.9. The module supports different backplane pin field assignments to enable rear I/O access for the XMC module. The following profiles are supported:

  • P3w1-P64s (XMC site 1)
    • P5W1-P64s (XMC site 2)
  • P3w1-P64s+P4w1-X12 (XMC site 1)
    • P5w1-P64s+P4w1-X12 (XMC site 2)
  • P3w1-P64s+P4w1-X12d+X8d (XMC site 1)
    • P5w1-P64s+P6w1-X12d+X8d (XMC site 2)
  • P3w3-X38s+X8d+P4w1-X12d (XMC site 1)
    • P5w3-X38s+X8d+P6w1+X12d (XMC site 2)
  • P3w3-X38s+P4w1-X12d (XMC site 1)
    • P5w3-X38s+P6w1-X12d (XMC site 2)
  • P3w3-X38s+P4w1-X12d+X8d (XMC site 1)
    • P5w3-X38s+P6w1-X12d+X8d (XMC site 2)

The unit is available in a range of temperature and shock/vibration specifications per ANSI/VITA 47. Refer to ordering options.

The module has front JTAG port as well as JTAG routed to P0. The JTAG is routed to each XMC and/or PMC module if XMC/PMC modules are present on the carrier. This provide access to the full JTAG chain route.

The VPX105, in addition to having dual XMC/PMC, could be utilized as the PCIe Gen3 switch in the overall system architecture. The module supports up to four PCIe Virtual domains (allowing four hosts in the system).

The health management can monitor the sensors of each XMC module.
