Single-chip design boosts Gigabit Ethernet PMCs

SBS Technologies has strengthened its Gigabit Ethernet product line by introducing eight PCI Mezzanine Cards built using a single chip architecture.

SBS Technologies has strengthened its Gigabit Ethernet product line by introducing eight PCI Mezzanine Cards (PMCs) built using a 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 multichip Gigabit Ethernet PMCs.

"Our new Gigabit Ethernet PMCs meet the growing demands of both the commercial and government markets for cost-effective industry standard, high-performance I/O.

Using a single MAC/PHY chip design enhances performance by reducing the number of PCI-to-PCI bridges and components on the cards, as well as allowing us to produce a card that is conduction cooled friendly", said Clarence Peckham, President of SBS Technologies' Commercial and Government Group.

All eight Gigabit Ethernet cards are single-width 32/64bit 33/66MHz PCI, 66/133MHz PCI-X PMCs with front panel I/O access, autonegotiating protocol selection and support for Jumbo frames.

Transmit and receive FIFOs, 64Kbyte 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.

Drivers 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 PCIbus as a multi-function device reducing the number of PCI-to-PCI bridges required.

All eight Gigabit Ethernet PMCs are available now.

Pricing starts at $300.
