DP83850C 100 Mb/s TX/T4 Repeater Interface Controller (100RIC™) June 1998 DP83850C 100 Mb/s TX/T4 Repeater Interface Controller (100RIC™) General Description Features The DP83850C 100 Mb/s TX/T4 Repeater Interface Con- s IEEE 802.3u repeater and management compatible troller, known as 100RIC, is designed specifically to meet s Supports Class II TX translational repeater and Class I the needs of today's high speed Ethernet networking sysT4 repeater tems. The DP83850C is fully compatible with the IEEE s Supports 12 network connections (ports) 802.3 repeater's clause 27. s Up to 31 repeater chips cascadable for larger hub appliThe DP83850C supports up to twelve 100 Mb/s links with cations (up to 372 ports) its network interface ports. The 100RIC can be configured s Separate jabber and partition state machines for each to be used with either 100BASE-TX or 100BASE-T4 PHY port technologies. Larger repeaters with up to 372 ports may be constructed by cascading DP83850Cs together using s Management interface to DP83856 allows all repeater the built-in Inter Repeater bus.
