A SUMIT-ISM-compatible Gigabit Ethernet module is designed for high-speed networking connectivity in small form factor, industrial embedded applications. The PXM-GIGE from WinSystems is a 90 x 96 mm module that connects to 10/100/1000 Mbit/s networks using standard Category 5 (CAT5) unshielded twisted pair (UTP) copper cables. It offers a stackable PCI Express expansion on a PC/104 module with the addition of the industry-standard high-speed SUMIT connector. It plugs directly into WinSystems’ PXM-C388-S, a 1.66 GHz Atom N455-based SBC as well as other SUMIT-ISM-compatible products available elsewhere.

The PXM-GIGE is based upon the Intel 82573 controller whose architecture is optimized to deliver both high performance and PCIe bus efficiency with the lowest power and smallest size. The 82573 efficiently handles packets with minimum latency by combining a parallel and pipelined logic architecture optimized for Gigabit Ethernet and independent transmit and receive queues. IEEE 802.3ab Auto-Negotiation, IEEE 802.3x-compliant flow control, adaptive equalization, echo cancellation and crosstalk cancellation are supported as well.

The PXM-GIGE module is wired to the x1 PCIe lane of the SUMIT-A connector and automatically selects the first available link. The PC/104 connector is supported for legacy stacks. It requires only +5 volts at 0.67A and will operate from -40° to +85°C. The PXM-GIGE supports Linux, Windows and other x86-compatible real-time operating systems. Free drivers are available from the WinSystems’ website. Quantity one pricing is $199.
