SBS Technologies, represented by Metromatics , has strengthened its Gigabit Ethernet product line by introducing eight PCI Mezzanine Cards (PMCs) built with single chip architecture.
Designed to provide full functionality while reducing the number of chips and components required, SBS' new PMCs offer a significantly improved price/performance ratio over multi-chip Gigabit Ethernet PMCs
All eight cards are single-wide 32/64 bit 33/66MHz PCI, 66/133MHz PCI-X PMCs with front panel I/O access, auto-negotiating protocol selection, and support for jumbo frames.
Transmit and receive FIFOs, 64kB total per port, allow back-to-back transmissions with minimal interface latency. All components and traces avoid the board area that would be used for a stiffener bar, making the PMCs compatible with ruggedised and conduction cooled CPUs.
Drives for VxWorks, Linux, and Windows NT/2000 are available.
Single interface Gigabit Ethernet PMCs are based on the Intel 82545EM Ethernet chip that provide integrated low powered MAC/PHY functionality.
For PMCs with two interfaces, dual integrated low-powered MAC/PHY functionality is supplied by the Intel 82546EB that appears on the PCI bus as a multi-function device reducing the number of PCI-to-PCI bridges required.
