CompactPCI Gigabit Ethernet Controller
Universal Host Adapter 10/100/1000Mbps

Ethernet is a real megatrend for connecting systems in a heterogeneous environment. With its CN5-GONG EKF introduces a Gigabit Ethernet networking interface controller (NIC) for CompactPCI® systems.

The 3U board is equipped with a new generation single-chip controller. Attachment to the local network across the RJ-45 jack requires an ordinary CAT5/6 twisted-pair copper cable only, which is suitable for distances up to more than 100m. While providing the 1000Base-T standard for fastest data transfer rates, compatibility is maintained to 100Base-TX and even 10Base-T based hubs and switches.

Gigabit Ethernet has been designed to use existing cabling and equipment, hence simplifying the migration process. Integrating the 1000Mbps CN5-GONG NIC into any CPCI system not only allows for remarkably higher data throughput, but also reduces the network load considerably due to shortened transfer times.

The CN5-GONG is provided with a 32/64-bit CPCI interface, and can be operated either at 33MHz or 66MHz bus clock. While being compatible to all CPCI systems, the optimum performance will be achieved within a 64-bit/66MHz system.

CN5-GONG - Gigabit Ethernet NIC


The design of the CN-5 GONG is based on a modern single-chip integrated MAC and PHY, thus minimizing the power consumption. The board is provided with a 128kx8 Flash EPROM, suitable for an extended BIOS (booting over network).

The CN5-GONG can be integrated smoothly into any existing networking environment. In order to profit from its Gigabit Ethernet capability, a Gigabit switch must be used accordingly for attachment. Existing facility cabling must provide strapping of all 8 pin positions of the RJ-45 jack.

The CN5-GONG is a 3U (single size) Eurocard. For 6U CPCI systems, a mounting kit (CR9-ADAPT) is available, which expands the front panel to 6U height.
