Apr. 12, 2001--SBS Technologies, Inc. announced two new additions to the expanding family of PMC Gigabit Ethernet products. One board offers dual 1000BaseT capability and the other offers multimode fiber optic technology.

SBS Technologies, Inc. (Nasdaq: SBSE) announced two new additions to the expanding family of PMC Gigabit Ethernet products. One board offers dual 1000BaseT capability and the other offers multimode fiber optic technology. These new products double the density of Gigabit Ethernet ports and increase performance over the existing family of PMC products, including the PMC-Gigabit-SF and PMC-Gigabit-ST that offer single interface ports.

Both the PMC-Gigabit-DTX and PMC-Gigabit-DFX offer two high-performance PMC (Peripheral Component Interconnect (PCI) standard bus) interface controller ports and two Gigabit Ethernet interfaces using two Intel 82543 Gigabit Ethernet controllers. These two controllers interface to the PMC bus via an Intel 21154 Bridge chip supporting 32-bit and 64-bit PCI up to 66 MHz. These boards were specifically designed for applications requiring high-speed data throughput and low latency transmission, such as high-speed image transfer, critical industrial control operations and data communications applications.

The PMC-Gigabit-DTX includes 64Kbytes of FIFO buffer memory per port, allowing back-to-back transmissions with minimum interface latency. It also features a 10BaseTx, 100BaseTx and 1000BaseT auto-detection CSMA/CD interface controller.

The physical interface is supported via Marvell 88E1020 PHY. It offers a number of sophisticated features, including auto negotiation, collision detection, link detection, 4B/5B encoding/decoding (100BaseTx) and scrambling/descrambling (100BaseTx), half duplex/full duplex. Standard network connection is accomplished through two front-panel RJ45 connectors. The module is compliant with standard single-wide PMC IEEE P1386.1 and PCI 2.2 specifications. The DTX complies with the IEEE 802.3 specification for 10BaseTx, 100BaseTx and IEEE 802.3ab specification for 1000BaseT over category 5 twisted pair cable. Full-duplex mode fully supported. Half-duplex mode supported in 10BaseTx and 100BaseTx.

The PMC-Gigabit-DFX includes 64 Kbytes of receive/transmit FIFO buffer memory per port, allowing back-to-back transmissions with minimum interface latency. The physical interface is supported via the Vitesse VSC7123. Standard network connection is accomplished through two front panel LC form factor multimode fiber transceivers. The module is compliant with standard single-wide PMC IEEE P1386.1 and PCI 2.2 specifications. The DFX complies with the IEEE 802.3z specification. Full-duplex mode is supported.

The PMC Gigabit -DTX is available in May with list pricing beginning at $1,380. The PMC Gigabit -DFX is available in May with list pricing beginning at $1,680.
