DP83902A ST-NIC^TM

Serial Network Interface Controller for Twisted Pair

General Description

Features

Single chip solution for IEEE 802.3, 10BASE-T

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.

Integrated controller, ENDEC, and transceiver

Full AUI interface

No external precision components required

3 levels of loopback supported

Transceiver Module

Integrates transceiver electronics, including:

Ð Transmitter and receiver

Ð Collision detect, heartbeat and jabber timer

Ð Link integrity test

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.

Link disable and polarity detection/correction

Integrated smart receive squelch

Reduced squelch level for extended distance cable op-

eration (100-pin QFP version)

ENDEC Module

10 Mb/s Manchester encoding/decoding, plus clock re-

covery

The integrated ENDEC module allows Manchester encod-

ing and decoding via a differential transceiver and phase

lock loop decoder at 10 Mbit/sec. Also included are colli-

sion detect translator and diagnostic loopback capability.

The ENDEC module interfaces directly to the transceiver

module, and also provides a fully IEEE compliant AUI (At-

tachment Unit Interface) for connection to other media

Transmitter half or full step mode

Squelch on receive and collision pairs

Lock time 5 bits typical

Decodes Manchester data with up to 18 ns jitter

MAC/Controller Module

100% DP8390 software/hardware compatible

transceivers.

(Continued)

Dual 16-bit DMA channels

16-byte internal FIFO

Efficient buffer management implementation

Independent system and network clocks

Supports physical, multicast and broadcast address fil-

tering

Network statistics storage
