Professionals are creating files in ever-increasing amounts as they build their libraries of information, data, and schematics. These changes create demand for high-performance workstations that store large files quickly and efficiently while delivering fast Ethernet connections and strong security precautions. To meet these requirements, National Semiconductor offers advanced workstation components from highly integrated server I/O, Ethernet, and TCG-compliant security devices to power management. On-board thermal management systems maximize the performance of the CPU and other various components. With worldwide workstation shipments expected to increase, analog-based solutions will play a larger and more important role.

Component Highlights

*Single/Quad Gigabit Ethernet PHY - delivers 10/100/1000 Gbps performance with advanced features and capabilities in a small, low-powered device.

*RS232 - low-power dual driver/receiver featuring an onboard DC-to-DC converter.

*LDO - low dropout voltage positive regulators with a maximum dropout of 1.5V at 5A.
