Gigabit Ethernet LAN Module


WinSystems, a supplier of PC/104 Single Board Computers (SBCs) and I/O modules, today announced a two channel, Gigabit Ethernet LAN module designed to offer flexible, high-performance networking connectivity for industrial embedded applications.  Named the PPM-GIGE-2, it offers self-stacking I/O expansion on PC/104, EPIC, and EBX SBCs based on the industry-standard PC/104-Plus form factor.  This add-in module uses standard RJ-45 connectors to plug into 10/100/1000 Mbps networks using standard Category 5 (CAT5) unshielded twisted pair (UTP) copper cables.             

Two Realtek RTL8110s are the Ethernet controllers used by the PPM-GIGE-2.  They are supported by a wide range of operating systems including Windows®, Linux, and other x86 real time operating systems.  These onboard Gigabit Ethernet controllers combine a triple-speed, IEEE 802.3 compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, 32-bit PCI bus controller, and embedded memory.  With state of-the-art DSP technology and mixed-mode signal technology, it offers high-speed transmission over CAT 5 UTP cable.  

Functions such as crossover detection and auto-correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capability at gigabit data speeds. The PPM-GIGE-2 requires only +5 volts at 500 mA (2.5W).  It will operate from -40°C to +85°C.  The module measures 90mm x 96mm (3.6” x 3.8”) and weighs only 88 grams (3 ounces).
