Vitesse Semiconductor Corporation engages in the design, development, manufacturing, and marketing of integrated circuits (ICs) for systems manufacturers in the communications and storage industries. The company provides laser drivers, transimpedance amplifiers, and post amplifiers that serve as the physical connection to the fiber optic cable. It offers physical layer devices that convert high-speed analog signals from the physical media devices to digital signals; and involve in clock and data regeneration, and multiplexing/demultiplexing for the fiber channel and gigabit Ethernet markets. The company provides network processors; software-programmable microprocessors for networking and communications functions, such as classification, filtering, policing, grooming, forwarding, and routing; and traffic management ICs that reside on a line card between the network processor and the switch fabric, as well as perform the policing, queuing, and buffering functions. It also offers switches for receiving data from a line card and routing it to its proper destination; enterprise local area network (LAN) products, such as transceivers, switches, and media access controllers that address gigabit Ethernet applications in the LAN; and storage and serial backplane products, such as serialisers and deserialisers, transceivers, retimers, and port bypass circuits, as well as switches, expanders, enclosure management devices, and RAID controllers. The company markets its product in the United States, Japan, Canada, Singapore, Hong Kong, and the United Kingdom. Vitesse Semiconductor was co-founded as Vitesse Electronics Corporation in 1984 by Louis Tomasetta and changed its name to Vitesse Semiconductor Corporation in 1987.
