DP83902AVLJ

Product Summary

The DP83902AVLJ Serial Network Interface Controller for Twisted Pair (ST-NIC) is a microCMOS VLSI device designed for easy implementation of CSMA/CD local area networks. These include Ethernet (10BASE5), Thin Ethernet (10BASE2) and Twisted-pair Ethernet (10BASE-T). The overall ST-NIC solution provides the Media Access Control (MAC) and Encode-Decode (ENDEC) with an AUI interface, and 10BASE-T transceiver functions in accordance with the IEEE 802.3 standards. The DP83902AVLJ 10BASE-T transceiver fully complies with the IEEE standard. This functional block incorporates the receiver, transmitter, collision, heartbeat, loopback, jabber, and link integrity blocks as defined in the standard. The transceiver when combined with equalization resistors, transmit/receive filters, and pulse transformers provides a complete physical interface from the DP83902AVLJ ENDEC module and the twisted pair medium.
