DescriptionThe DP83950B Repeater Interface Controller ``RIC'' may be used to implement an IEEE 802.3 multiport repeater unit. IDP83950B RICTM fully satisfies the IEEE 802.3 repeater specification including the functions defined by the repeater, segment partition and jabber lockup protection state machines. The DP83950B RICTM has an on-chip phase-locked-loop (PLL) for Manchester data decoding, a Manchester encoder and an Elasticity Buffer for preamble regeneration. Each DP83950B RICTM can connect to 13 cable segments via its network interface ports. One port is fully AUI compatible and is able to connect to an external MAU using the maximum length of AUI cable.
The other 12 ports have integrated 10BASE-T transceivers. These transceiver functions may be bypassed so that the RIC may be used with external transceivers, for example DP8392 coaxial transceivers. In addition, large repeater units, containing several hundred ports may be constructed by cascading RICs together over an Inter-RIC bus. The DP83950B RICTM is configurable for specific applications. DP83950B RICTM provides port status information for LED array displays and a simple interface for system processors.
The DP83950B RICTM posseses multifunction counter and status flag arrays to facilitate network statistics gathering. A serial interface, known as the Management Interface is available for the collection of data in Managed Hub applications.
