DISTINCTIVE CHARACTERISTICS
s Connects the standard AUI port interface to
10BASE–2 (Cheapernet) connector.
s Jumper selectable Signal Quality Error (SQE)
test allows evaluation in both node and
repeater applications.
s Self contained board facilitates rapid
evaluation of the AUI -to-coax system block,
and demonstrates optimal analog design
criteria.
GENERAL DESCRIPTION
The Am7996EVAL-HW board is a self contained mod-
ule that implements all the functions of a Medium At-
tachment Unit (MAU) for IEEE 802.3 10BASE–2
(Cheapernet). This 3”x3” board can be used to connect
any AUI port interface to the ‘thin’ coaxial cable used in
Cheapernet networks. This system permits the network
designer to monitor signals on the card to increase his

understanding of IEEE 802.3 standards and conven-
tions. A jumper selectable SQE test enable/disable lets
the board function in both user node or network repeater
applications. In addition, optimal PC board layout is em-
ployed. The Am7996EVAL-HW kit comes complete with
schematics, application notes, and coaxial cable con-
nection hardware.
