PMC682/E is an Ethernet NIC providing one 10/100BaseTX engine on a PMC. The engine is capable of full duplex operation in both 10 and 100Mbit modes. A PCI to PCI bridge couples the Ethernet interface to the host PCI bus ensuring high performance with minimal PCI loading. The PMC682/E features full auto-negotiation facility allowing automatic configuration to the highest possible operating mode. This includes the option for automatic determination of both bandwidth and full duplex operation. Two PMC682/E boards can be directly cabled with a simple "cross-over". This configuration creates a full duplex 100Mbit dedicated data path - delivering high bandwidth at very low cost. More complex,dedicated interconnects can be created using a hub or switch. Both point-to-point and switched hubs, in full duplex mode, remove many determinism concerns raised with traditional Ethernet solutions. This makes the PMC682/E an excellent candidate for high performance interconnects that require real time determinism. Software drivers are available for most popular operating systems including Windows, Linux, LynxOS, VxWorks, and Solaris. These drivers have been carefully designed and implemented to fit within the LAN protocol stack of the host operating system. In this way, all facilities available from the host OS can be utilized across the PMC682/E.
