78Q8392L

Low Power Ethernet

Coaxial Transceiver

February 1998

DESCRIPTION

FEATURES

The 78Q8392L Ethernet Transceiver is a low power

BiCMOS coax line transmitter/receiver. The device

includes analog transmit and receive buffers, a 10

MHz on-board oscillator, timing logic for jabber and

heartbeat functions, output drivers and bandgap

reference, in addition to a current reference and

collision detector.

•

Very low power consumption

Compliant with Ethernet II, IEEE 802.3

10Base5 and 10Base2

•

Integrates all transceiver functions except

signal and power isolation

Innovative

design

minimizes

external

components count and power consumption

This transceiver provides the interface between the

single-ended coaxial cable signals and the

Manchester-encoded differential logic signals.

Primary functional blocks include the receiver,

transmitter, collision detection and jabber timer. This

IC may be used in either internal or external MAU

environments.

•

Jabber timer function integrated on chip

Externally selectable CED heartbeat allows

operation with IEEE 802.3 compatible

repeaters

•

Squelch circuitry at all inputs rejects noise

Power-on reset and test modes

Advanced BiCMOS process

The 78Q8392L is available in 16-pin plastic and 28-

pin PLCC packages.
