The PMC661J, implementing 100BaseTX connectivity, is capable of full duplex operation in both 100 and 10 Mbit modes. The PMC661J Ethernet/PCI interface includes a powerful DMA engine with very deep FIFO buffers. This assures continuous, full bandwidth operation with minimum PCI overhead. In addition, card edge PCI systems can be accommodated using GE Fanuc Embedded Systems' PMC239 adapter, for rapid prototype and development.
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 state-of-the-art PCI/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. In addition, card edge PCI systems can be accommodated using GE Fanuc Embedded Systems' PMC239 adapter for rapid prototype and development.
The PMC661J features a 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 PMC661J 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 PMC661J an excellent candidate for high performance interconnects that require real-time determinism.
