[ ADMtek Incorporate ]

Overview

ADM6308, a single chip, is a 10/100Mbps eight-port stand-alone switching controller with built-in data buffer memory which provides low cost and simple solution though a high integration design. Eight Reduced MII interfaces are designed for 10BASE/100BASE ports. MAC controller, switch engines and data buffer memory are built-in. The chip can fit to desktop or SOHO applications, and each 10/100M port directly connects either 10BASE or 100BASE devices. Additionally, ADM6308 breaks the distance limitation of 10BASE or any class 100BASE repeaters, and increases throughput.
