78Q8392L
Low Power Ethernet
Coaxial Transceiver
February 1998
DESCRIPTION
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.
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.
The 78Q8392L is available in 16-pin plastic and 28-
pin PLCC packages.
