SPR418A - PMC/XMC hybrid carrier for PCI Express slots.

SPR418A Carrier Card


The SPR418A is a short form factor PCI Express carrier for either PMC or XMC modules which allows for use of these cards in traditional PC's with slots supporting 8 or 16 lane PCI Express (Gen 1 or 2).

The SPR418 provides high performance PCI Express capability by delivering power and cooling necessary to ensure reliability and by providing unprecedented flexibility in its support for a range of connectivity options. It allows for taking full advantage of the high speed serial bus architecture inherent in newer XMC designs.

It can be ordered to host either a PMC module supporting up to PCI-X transfer speeds, or an XMC module supporting up to 8 lane PCI Express speeds: the Gen2 x8 PCI Express interface to the host allows for unimpeded data transfers at the full rate supported by the mezzanine card. An integrated fan supplies additional cooling to the mezzanine card for optimum reliability, while support for up to 25W of power is well in excess of that required by the PMC and XMC specifications - contributing to both performance and reliability.

The SPR418A can be ordered with connectors which provide additional I/O and usage modes. J4 connectivity is provided to an optional 80-pin KEL connector (similar to the connector used for FPDP VITA 17). J16 can be connected to two SFF connectors providing up to 4 lanes of high-speed serial connectivity each via readily available cables. A standard PC power connector can be fitted for standalone operation for mezzanines that do not require interaction with a host.
