Application· High Density 10/100/100BASE-T LAN & MAN Switches and Routers
· High Performance Workstations and Multi-Port Server NICs
· Workgroup LAN Switches and Routers
· Multi-Port Fiber to Copper Media Converters
· Gigabit Ethernet-based SAN, NAS, and MAN SystemsDescriptionThe VSC8234 is the industry's smallest, lowest power quad port Gigabit Ethernet transceiver for multi-port SGMII and SerDes switch and router applications. The VSC8234's power consumption is 30% lower than the next best competitor. Its serial MAC interface reduces pin count requirements by 66% (over RGMII) to 83% (over GMII). The device's compact 19mm x 19mm BGA package makes it ideal for the highest-density SGMII and SerDes switch applications. Vitesse's mixed signal and DSP architecture yields robust performance, supporting both full and half duplex 10BASE-T, 100BASE-TX, and 1000BASE-T over >140m of Category 5, unshielded twisted pair (UTP) cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise.
