Am7996 Stand-Alone
Evaluation
Board
This is
a 3 x 3
inch
stand-alone evaluation board which
integrates the
IEEE-802.3
transceiver, Am7996 along with
external components and a
DC-DC
converter.
The
board
interfaces to
an Ethernet
controller (Demo
boards 1
,2 or
equivalent)
via
a
15-pin
connector.
It
also interfaces to
the
coax cable, a terminated
RG 58
(NU or
C/U)
cable seg-
ments, via a
BNC
connector for communicating with other
nodes
in
the
network. This
board
utilizes
an optimized
PC
layout for the Am7996.
SOFTWARE SUPPORT
The following outlines the· purpose of each software pack-
age so that the user can get the board and software pack-
age which suits his
application.
1.
Demo board 1
&
2 software
(LANCE
Debug
Monitor)
This software
package
is an educational tool
for
both
hardware
and software engineers
to learn
about
AMD
's
Ethernet
chipset.
It also
gives an inside look to the opera-
tion
of the
LANCE
(Am7990) and
its
companion parts,
the
Am7992
and
Am7996. This
software is
useful
for creating
different boundary conditions and serves as a tool for
observing different signals in a controlled environment with
scope
loop
capability.
This board is recommended as a learning tool in the initial
stage of design development. The software will also be
useful
for correlation
in
duplicating
the
user's system envi-
ronment. One Demo board is sufficient at
initial
stage
when using this software for learning about
the
chipset and
exercising some limited
functions
