Cyclone's PMC Modules provides I/O expansion and flexibility by allowing customers to add a wide range of I/O interfaces to Cyclone's CompactPCI products. Cyclone's PCI and CompactPCI cards support one or two modules per board. Designers can mix and match standard and custom modules to meet unique I/O requirements.
The PMC Module is an IEEE standard (IEEE 1386). The standard uses the PCI bus as an electrical foundation, providing 32-and 64-bit transfers at 33 and 66 MHz clock speeds. The PMCX-65 supports PCI-X electrical interface at up to 133 MHz. The PMCX-65 is backward compatible with the slower PCI speeds.
