Product specification  
Low-power coaxial Ethernet transceiver  
NE83C92  
DESCRIPTION  
PIN CONFIGURATION  
The NE83C92 is a low power BiCMOS coaxial transceiver interface  
(CTI) for Ethernet (10base5) and Thin Ethernet (10base2) local area  
networks. The CTI is connected between the coaxial cable and the  
Data Terminal Equipment (DTE) and consists of a receiver,  
transmitter, receive-mode collision detector, heartbeat generator and  
jabber timer (see Block Diagram). The transmitter output connects  
directly to a doubly terminated 50cable, while the receiver output,  
collision detector output and transmitter input are connected to the  
DTE through isolation transformers. Isolation between the CTI and  
the DTE is an IEEE 802.3 requirement that can be met on signal  
lines by using a set of pulse transformers. Power isolation for the  
CTI is achieved using DC-to-DC conversion through a power  
transformer.

The part is fully pin compatible with the industry standard 8392, but  
has substantially lower current consumption, is fully compliant with  
the IEEE802.3 standard, and has additional features such as  
automatic selection between AUI and coaxial connections, and  
requires no external pull-down resistors for local integrated MAU  
application.

A PACKAGE  
The NE83C92 is manufactured on an advanced BiCMOS process  
and is available with PLCC package which make it ideally suited to  
lap-top personal computers or systems where low power  
consumption, limited board space and jumperless design is  
required. Refer to selection flow chart for optimal application.
