Abaco Systems / Ramix PMC671TX Gigabit Ethernet Interface Module

The Abaco Systems / Ramix PMC671TX is a single-port Gigabit Ethernet interface module designed for PMC (PCI Mezzanine Card) form factor systems. It offers auto-negotiation for 10/100/1000Mbit Ethernet speeds and supports full-duplex operation. The module features an automatic MDI/MDIX switch-over capability, allowing it to detect and correct for both cross-over and non-cross cables. It is equipped with a powerful DMA engine and deep FIFO buffers (64KB) to ensure continuous, full-bandwidth operation with minimal PCI overhead. This module is suitable for high-performance interconnects requiring real-time determinism, and can be directly cabled with another PMC671TX for a full-duplex 1000Mbit dedicated data path.
