PMC to XMC Converter

PDF print version of this specification

The PMC to XMC Converter facilitates the use of a PCI Mezzanine Card (PMC) Adapter in a Switched Mezzanine Card (XMC) system. This converter can be used either for production testing or field testing of PMC Adapters using an XMC-only host. It is also possible to use the converter in production systems, but an extra slot will be required to accommodate the combination of the PMC Adapter and the PMC to XMC Converter.

The adapter provides a single lane PCIe signal interface on the host XMC site. A 33 or 66 MHz PCI Bus signal interface with either 32 bit or 64 bit bus extension is provided to the host PMC site.

The PMC Jn4 I/O signals are routed through to the host PMC site.
