Abaco Systems / Ramix PMC677TX Quad 10/100/1000 BaseT Ethernet Interface

The Abaco Systems/Ramix PMC677TX is a quad 10/100/1000 BaseT Ethernet interface on a PMC form factor. This network interface card is designed to provide maximum 1000Mbit Ethernet connectivity with four ports, supporting full-duplex operation on each channel. It integrates a powerful DMA engine with 64KB deep FIFO buffers, ensuring continuous, full-bandwidth operation with minimal PCI overhead. The PMC677TX offers advanced host off-loading features, including packet filtering, SNMP and RMON statistic counters, hardware TCP checksum off-loading, and various address filtering modes. This makes it suitable for high-performance interconnects requiring real-time determinism. Software drivers are available for popular operating systems such as VxWorks, Linux, LynxOS, Windows NT, and Solaris.
