PMC610J4

PMC610J4 is a PMC 10/100BaseTX Ethernet NIC with four 10/100Mbit Ethernet ports routed through the rear panel. The four 10/100BaseTX Ethernet engines are each capable of full duplex operation in both 10 and 100 Mbit modes. Each of the Ethernet/PCI interfaces includes a powerful DMA engine with very deep FIFO buffers. This assures continuous, full bandwidth operation with minimum PCI overhead. A PCI to PCI bridge couples the Ethernet interfaces to the host PCI bus, assuring high performance with minimum PCI loading. The PCI bus can run at 66 MHz. PMC610J4 features full auto-negotiation allowing automatic configuration to the highest possible operating mode. This includes the option for automatic determination of both bandwidth and full duplex operation. Two PMC610J4 NICs can be directly cabled with a simple "cross-over". This configuration creates a full duplex 800Mbit 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 PMC610J4 an excellent candidate for high performance interconnects that require real time determinism. Software drivers are available for most popular operating systems such as VxWorks, Linux, LynxOS,and Windows NT. These drivers have been carefully designed and implemented to fit within the LAN protocol stack of the host operating system. Thus all facilities available from the host OS can be used across the PMC610J4. These drivers allow user control over the PMC610J4 auto-negotiation capability.
