Serial Network Interface Controller for Twisted Pair
General Description
The DP83902A Serial Network Interface Controllerfor
Twisted Pair (ST-NIC)isa microCMOS VLSI devicede-
signedfor easy implementationof CSMA/CD local areanet-
works. These include Ethernet (10BASE5), Thin Ethernet
(10BASE2) and Twisted-pair Ethernet (10BASE-T). The
overall ST-NIC solution providesthe Media Access Control
(MAC)and Encode-Decode (ENDEC) withanAUI interface,
and 10BASE-Ttransceiver functionsin accordancewiththe
IEEE 802.3 standards.
The DP83902A’s 10BASE-T transceiver fully complies with
the IEEE standard. This functional block incorporatesthe
receiver, transmitter, collision, heartbeat, loopback, jabber,
andlink integrity blocksas definedinthe standard. The
transceiver when combined with equalization resistors,
transmit/receive filters,and pulse transformers providesa
complete physical interface fromthe DP83902A’s ENDEC
moduleandthe twistedpair medium.
The integrated ENDEC module allows Manchester encod-
ing and decodingviaa differential transceiver and phase
lock loop decoderat10 Mbit/sec. Also includedare colli-
sion detect translator and diagnostic loopback capability.
The ENDEC module interfaces directlytothe transceiver
module,and also providesa fully IEEE compliantAUI(At-
tachment Unit Interface)for connectionto other media
transceivers. (Continued)
