The DP83858 100 Mb/s TX/T4 Repeater Interface Controller, known as 100RIC8, is designed specifically to meet the needs of today's high speed Ethernet networking systems. The DP83858 is fully compatible with the IEEE 802.3 repeater's clause 27. This device is targeted at low port count managed and unmanaged repeater applications. The DP83858 supports up to eight 100 Mb/s links with its network interface ports. The 100RIC8 can be configured to be used with either 100BASE-TX or 100BASE-T4 PHY technologies. Larger repeaters may be constructed by cascading DP83858s together using the built-in Inter Repeater bus.
