Abaco Systems / Ramix PMC676TX Dual Port GigE Controller

The Abaco Systems / Ramix PMC676TX is a dual-port Gigabit Ethernet controller on a PMC (PCI Mezzanine Card) form factor, designed for high-performance embedded systems. It provides two independent 10/100/1000Base-TX Ethernet ports with RJ-45 connectors. The card features a robust DMA engine for each port, coupled with deep FIFO buffers (64 Kbytes), ensuring continuous, full-bandwidth operation with minimal PCI overhead. This design makes the PMC676TX suitable for demanding applications requiring real-time determinism. The card supports various address filtering modes, hardware TCP checksum offloading, and packet filtering based on checksum errors, further enhancing its efficiency and offloading tasks from the host system. It is compatible with PCI-X and PCI 64/66 MHz interfaces and supports signaling for both 3.3 V and 5 V. Software drivers are available for common operating systems, including Windows, Linux, VxWorks, LynxOS, and Solaris.
