General Description
The DP83902A Serial Network Interface Controller for
Twisted Pair (ST-NIC) is a microCMOS VLSI device de-
signed for easy implementation of CSMA/CD local area net-
works. 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 DP83902A's 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 DP83902A's ENDEC
module and the twisted pair medium.
