DP8392A/NS32492A Coaxial Transceiver Interface

General Description

Features

Compatible with Ethernet II, IEEE 802.3 10Base5 and

10Base2 (Cheapernet)

The DP8392A Coaxial Transceiver Interface (CTI) is a coax-

ial cable line driver/receiver for Ethernet/Thin Ethernet

(Cheapernet) type local area networks. The CTI is connect-

ed between the coaxial cable and the Data Terminal Equip-

ment (DTE). In Ethernet applications the transceiver is usu-

ally mounted within a dedicated enclosure and is connected

to the DTE via a transceiver cable. In Cheapernet applica-

tions, the CTI is typically located within the DTE and con-

nects to the DTE through isolation transformers only. The

CTI consists of a Receiver, Transmitter, Collision Detector,

and a Jabber Timer. The Transmitter connects directly to a

50 ohm coaxial cable where it is used to drive the coax

when transmitting. During transmission, a jabber timer is ini-

tiated to disable the CTI transmitter in the event of a longer

than legal length data packet. Collision Detection circuitry

monitors the signals on the coax to determine the presence

of colliding packets and signals the DTE in the event of a

collision.

Integrates all transceiver electronics except signal

power isolation

Innovative design minimizes external component count

1.0 System Diagram

The CTI is part of a three chip set that implements the com-

plete IEEE 802.3 compatible network node electronics as

shown below. The other two chips are the DP8391 Serial

Network Interface (SNI) and the DP8390 Network Interface

Controller (NIC).

The SNI provides the Manchester encoding and decoding

functions; whereas the NIC handles the Media Access Pro-

tocol and the buffer management tasks. Isolation between

the CTI and the SNI is an IEEE 802.3 requirement that can

be easily satisfied on signal lines using a set of pulse trans-

formers that come in a standard DIP. However, the power

isolation for the CTI is done by DC-to-DC conversion

through a power transformer.
