Abaco Systems / Ramix PMC661 Ethernet Interface Card

The Abaco Systems / Ramix PMC661 is a PCI Mezzanine Card (PMC) designed to provide 100/10Mbit Ethernet connectivity for embedded systems. This interface card supports 100Base-TX and is capable of full-duplex operation at both 100 Mbit and 10 Mbit modes. The PMC661 features an Ethernet/PCI engine with a powerful DMA engine and deep FIFO buffers, ensuring continuous, full-bandwidth operation with minimal PCI overhead. It also incorporates an auto-negotiation facility for automatic configuration to the highest possible operating mode, including bandwidth and full-duplex settings. This makes the PMC661 suitable for high-performance interconnects requiring real-time determinism, especially when two PMC661 boards are directly cabled using a crossover connection to create a dedicated full-duplex 100Mbit data path.
