Product specification  
Coaxial transceiver interface for Ethernet/Thin Ethernet  
NE8392C  
DESCRIPTION  
PIN CONFIGURATION  
The NE8392C Coaxial Transceiver Interface (CTI) is a bipolar  
coaxial line driver/receiver 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 50Ω cable, 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  
normally available in a standard 16-pin DIP. Power isolation for the  
CTI is achieved using DC-to-DC conversion through a power  
transformer (see Figure 1, Connection Diagram).

During transmission the jabber timer is initiated to disable the CTI  
transmitter in the event of a longer than legal length data packet.  
Receive-mode collision detection circuitry monitors the signals on  
the coaxial cable to determine the presence of colliding packets and  
signals the DTE in the event of a collision. At the end of every  
transmission the heartbeat generator creates a pseudo collision for  
a short time to ensure that the collision circuitry is functioning  
correctly. The heartbeat function can be disabled for repeater  
applications.

The CTI is normally part of a three chip set that implements a  
complete Ethernet/ Thin Ethernet network interface for a DTE (see  
Figure 2, Interface Diagram). The other chips are a Serial Network  
Interface (SNI) and a Network Interface Controller (NIC). The SNI  
provides Manchester Encoding and Decoding while the NIC handles  
the media access protocol and buffer management tasks.
