Product specification

Low-power coaxial Ethernet transceiver

NE83Q92

DESCRIPTION

PIN CONFIGURATION

The NE83Q92 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 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. Power isolation for the

CTI is achieved using DC-to-DC conversion through a power

transformer (see Figure 1, Connection Diagram).

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

optional pull-down resistors (Figure 1, Note 4), and automatic

selection between AUI and coaxial connections.

The NE83Q92 is manufactured on an advanced BiCMOS process

and is available with PLCC and SOL packages 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 apllication.

• Optimal implementation can use 1 Watt DC-DC converter and

reduces external part count by not requiring external pull-down

resistors

• High efficiency AUI drivers automatically power-down under idle

conditions to minimize current consumption

• Automatically disables AUI drivers when no coaxial cable is

connected, allowing hard-wiring of AUI connection and

local/integrated CTI connection

• Smart squelch on data inputs eliminates false activations

• Advanced BiCMOS process for extremely low power operation
