78Q8392L/A03

Low Power Ethernet

Coaxial Transceiver

November 2008

DESCRIPTION

FEATURES

The 78Q8392L/A03 Ethernet Transceiver is a

•

Very low power consumption

replacement

for

the

SSI/TDK/Teridian

•

Compliant with Ethernet II, IEEE 802.3

78Q8392L/A02 coax line transmitter/receiver. Only a

single resistor value change is required for

upgrading an existing 78Q8392L/A02 design to the

78Q8392L/A03.

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.

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.

10Base5 and 10Base2

•

Integrates all transceiver functions except

signal and power isolation

Innovative

design

minimizes

external

component count and power consumption

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/A03 is available in lead-free 16-pin

plastic and 28-pin PLCC packages.
