OVERVIEW
This reference guide provides design consideration notes
relating to the Am7990 IEEE 802.3 (EthernetiCheapernet)
family
of products. Consult you local AMD sales office,
AMD representative or AMD authorized distributor for any
questions concerning device price and/or availability.

I. OVERVIEW OF Am7990
ETHERNET/CHEAPERNET FAMILY
The implementation of 10M bits/sec baseband networking
referred to as Ethernet or Cheapernet has been simplified
by the availability of three
devices-the Am7990 Local
Area Network Controller for Ethernet (LANCE), the
Am7992B Serial Interface Adapter (SIA) and the Am7996
Transceiver.
Devices
in the Am7990 Family support both Ethernet
and Cheapernet configurations. Cheapernet
is Ethernet on
cheaper cables, has fewer nodes, and shorter distance but
provides the same 10M bits/sec performance. This high-
performance chip family is compatible with IEEE 802.3, the
industry standard for EthernetiCheapernel.
The Am7990 Family was produced through joint devel-
opment work with Digital Equipment Corporation (Am7990
LANCE and Am7992B SIA) and 3COM (Am7996). Op-
timum performance of this family has been assured
through rigorous testing
in various network configurations.
The Am7990 LANCE features buffer management with
descriptor rings to substantially reduced CPU overhead. Its
24-bit-wide linear address provides direct memory address
(DMA) into the entire memory space of all major 16-bit
microprocessors.
The Am7992B SIA is a Manchester encoder-decoder
that provides the connection between the LANCE and the
Ethernet transceiver. The SIA features include transient
noise suppression and guaranteed signal threshold limits
in both data and collision paths.
The Am7996 Transceiver provides all the transmit,
receive and collision detection functions with respect to the
coax transmiSSion media. The Am7996 features include
an
optional Signal Quality Error (SQE) test function, and noise
rejection filters on both transmit and receive data.
Together, these three devices provide a complete inte-
grated solution for IEEE 802.3, Ethernet, and Cheapernet
networking applications.

and
is available on diskette for Demo board 2.
2. Demo board 2 Software
(Data Link Layer Software)
Ethernet Data-Link Software for the Am7990T PCturbo-
186 Evaluation Board
•
The combination of an AMD Ethernet Daughter Card
and an Orchid PCturbo-186 expansion board for an
IBM PC can, with this Data-Link software, create an
EthernetlCheapernet node in an IBM PC or compatible.
The combination is referred
to as the Am7990T Evalua-
tion board.
•
The software is structured to provide Data-Link services
to a Client Layer corresponding to ISO Network
and
higher layers. It is written in C and its source code is
included with the Am7990T and Am7990 (Multibus)
Evaluation Boards to serve
as an example of Physical
and Data-Link Layer implementations for LANCE-based
Ethernet systems. The software offers:
-Message-transfer
and delivery for the Client Layer
via Data Link service calls
(CONNECT, DISCON-
NECT, TRANSMIT, etc.) for more than one client
process at a time.
-Example Physical and Data-Link Layer procedures
for LANCE initialization, memory management, error
handling
and Client servicing.
• The 9 Data-Link Services provided are:
CONNECT: Set up a pairing between a Client
process and a unique Data-Link
Service-Access-Point identifier
(LSAP).
DISCONNECT: Remove a
CONNECTion to an
LSAP.
TRANSMIT: Send a designated set of packet
buffers to a destination (DLSAP).
This
is implemented as a Datagram
service, not a guaranteed, virtual-
circuit service. Such reliable serv-
ices would have to
be implemented
at the Client
Layer.
POST RPD:
POST RBD:
Post a Receive Packet Descriptor
and up to 4 packet buffers for the
Data Link to use when receiving
packets for the calling process
LSAP.
Post an additional packet buffer for
the caller's
LSAP..
8
CONFIGURE: Set up general parameters (e.g.,
buffers)
in the Data-Link system
for the purposes of network
management.
IA SETUP:
MC ADD:
Establish the node's physical net-
work address.
Add a multicast address for the
node to the LANCE's Logical Ad-
dress Filter.
MC REMOVE: Remove a multicast address.
• The protocol defined for communicating these
com-
mands from Client to Data Link provides for the
possibilities of:
-Multiple requests (Client processes).
-Individual command status and error reporting.
-Indirect control management via Request
and Base
COntrol Blocks shared between the client and Data-
Link processes.
-
Two mediating routines: the Host Message-Delivery
Mechanism
(HMDM); and the Data-Link Message-
Delivery Mechanism
(DLMDM)-the HMDM provides
control access for the Client, while
DLMDM does so
for the Data-Link itself.
•
In normal use, the CONFIGURE command first sets up
the LANCE and associated Data-Link parameters.
Then a Client process establishes its
LSAP and form-
ulates a REQUEST BLOCK to perform actual transmis-
sion of a packet. This is all done by calling HMDM from
the Client with an associated REQUEST BLOCK
containing the necessary command code, parameters
and addresses. As currently defined, the software is not
multiprocess,
so pOlling for status (e.g., received pack-
ets) is used.
3. LANCE Diagnostic Software
(not related to any
of the DEMO boards)
The LANCE Diagnostic program has been ported to
an IBM-XT and compiled with the Lattice C Compiler.
This program is menu driven and is comprised of six
major tests with increasing complexity. The code is
available
in C source code on 3 IBM PC diskettes and
is well documented and very readable. It consists of the
following modes.
Note: Only the first four items in the following list have
been checked
out-other items have not been
checked for errors.
LANCE
CSRTST
INITTST
The user-interface control program. It
provides menu-driven options and
er-
ror reporting.
A
test program for verifying that
LANCE control and status registers
can be read or write and bits can be
set or
reset according to specs.
A test program to verify the correct ini-
tialization and correct status reporting

and
is available on diskette for Demo board 2.
2. Demo board 2 Software
(Data Link Layer Software)
Ethernet Data-Link Software for the Am7990T PCturbo-
186 Evaluation Board
•
The combination of an AMD Ethernet Daughter Card
and an Orchid PCturbo-186 expansion board for an
IBM PC can, with this Data-Link software, create an
EthernetlCheapernet node in an IBM PC or compatible.
The combination is referred
to as the Am7990T Evalua-
tion board.
•
The software is structured to provide Data-Link services
to a Client Layer corresponding to ISO Network
and
higher layers. It is written in C and its source code is
included with the Am7990T and Am7990 (Multibus)
Evaluation Boards to serve
as an example of Physical
and Data-Link Layer implementations for LANCE-based
Ethernet systems. The software offers:
-Message-transfer
and delivery for the Client Layer
via Data Link service calls
(CONNECT, DISCON-
NECT, TRANSMIT, etc.) for more than one client
process at a time.
-Example Physical and Data-Link Layer procedures
for LANCE initialization, memory management, error
handling
and Client servicing.
• The 9 Data-Link Services provided are:
CONNECT: Set up a pairing between a Client
process and a unique Data-Link
Service-Access-Point identifier
(LSAP).
DISCONNECT: Remove a
CONNECTion to an
LSAP.
TRANSMIT: Send a designated set of packet
buffers to a destination (DLSAP).
This
is implemented as a Datagram
service, not a guaranteed, virtual-
circuit service. Such reliable serv-
ices would have to
be implemented
at the Client
Layer.
POST RPD:
POST RBD:
Post a Receive Packet Descriptor
and up to 4 packet buffers for the
Data Link to use when receiving
packets for the calling process
LSAP.
Post an additional packet buffer for
the caller's
LSAP..
8
CONFIGURE: Set up general parameters (e.g.,
buffers)
in the Data-Link system
for the purposes of network
management.
IA SETUP:
MC ADD:
Establish the node's physical net-
work address.
Add a multicast address for the
node to the LANCE's Logical Ad-
dress Filter.
MC REMOVE: Remove a multicast address.
• The protocol defined for communicating these
com-
mands from Client to Data Link provides for the
possibilities of:
-Multiple requests (Client processes).
-Individual command status and error reporting.
-Indirect control management via Request
and Base
COntrol Blocks shared between the client and Data-
Link processes.
-
Two mediating routines: the Host Message-Delivery
Mechanism
(HMDM); and the Data-Link Message-
Delivery Mechanism
(DLMDM)-the HMDM provides
control access for the Client, while
DLMDM does so
for the Data-Link itself.
•
In normal use, the CONFIGURE command first sets up
the LANCE and associated Data-Link parameters.
Then a Client process establishes its
LSAP and form-
ulates a REQUEST BLOCK to perform actual transmis-
sion of a packet. This is all done by calling HMDM from
the Client with an associated REQUEST BLOCK
containing the necessary command code, parameters
and addresses. As currently defined, the software is not
multiprocess,
so pOlling for status (e.g., received pack-
ets) is used.
3. LANCE Diagnostic Software
(not related to any
of the DEMO boards)
The LANCE Diagnostic program has been ported to
an IBM-XT and compiled with the Lattice C Compiler.
This program is menu driven and is comprised of six
major tests with increasing complexity. The code is
available
in C source code on 3 IBM PC diskettes and
is well documented and very readable. It consists of the
following modes.
Note: Only the first four items in the following list have
been checked
out-other items have not been
checked for errors.
LANCE
CSRTST
INITTST
The user-interface control program. It
provides menu-driven options and
er-
ror reporting.
A
test program for verifying that
LANCE control and status registers
can be read or write and bits can be
set or
reset according to specs.
A test program to verify the correct ini-
tialization and correct status reporting
of
the LANCE.

INTLOOP Internal loop test to verify packet
transmission/reception, chaining, and
CRCs. It also
verifies promiscuous,
normal and collision-test modes.
EXTLOOP -Verifies that packets can go out on the
Ethernet cable and be received in both
the promiscuous and normal mode. It
also verifies disabling of the receiver or
transmitter.
ETHERTST -Allows
the user to configure the size of
ring buffers and
transmit packets, it
then transmits packets and accumu-
lates statistics on number of trans-
missions, receptions, and errors on an
individual basis.
ECHO
UTILS
DEF
BUFFER
SYSTEM
When executed on a second LANCE
board it switches source and destina-
tion addresses and retransmits any
packets received. It also accumulates
statistics.
A set of general purpose utility mod-
ules that build initialization blocks,
build ring buffers, calculate or verify
CRCs,
and reads or writes CSR regis-
ters (5600 bytes).
Definitions of structures for initblock,
ring buffers, etc.
Allocate RAM space.
Character read/write routine, interrupt
handler in 8086 assembly language
(only
144 bytes of code).
The last 4 modules described above are modules for
writing code for the
LANCE. They can easily be studied
and understood.
The .DOC file on the diskette provides
additional comments on programming techniques for
the LANCE and also for porting this code to another
hardware configuration.
The code for the test modules show how to call the
various utility functions
to incorporate them into another
program. Studying CSRTST & INITTST
in conjuction
with UTILs, DEF and 10 will give the programmer a
good insight into the entire program.
Embedded into the code
are many compiler conditional
print statements that trace the execution of the pro-
gram. These are very useful for debugging; however,
they have a penalty of using more
RAM space. The
following
is a tabulation of memory utilization.
Code space without ETHERTST &
ECHO 21 K bytes
Entire Code Space 26K bytes
Code Space with
Debug Trace 40K bytes
RAM Space Max 16K bytes
RAM Space w/o ETHERTST & ECHO 6K bytes
This code space will vary depending upon the C com-
piler used.
There is a user manual which is the specification for
this software package which is available
in C source
code on 3
IBM PC diskett9S.

IV. DESIGN CONSIDERATIONS
Interfacing the Am7992B to Intel's 82586
Ethernet Controller
The AMD and Intel's Ethernet Controllers Serial Link in-
terfaces are functionally
similar. The interfacing glue logic
for the Am7992B and the 82586 shown here accom-
modates the active voltage levels, set-up
and hold timing
requirement of the two devices.
-Transmit Circuit: 82586
--> Am7992B
• IRTS is inverted for
TENA
• TXD is acceptable for TX
• /TXC requires continuous clock; therefore, SIA's
/TEST pin is grounded.
-Receive Circuit: Am7992B
--> 82586
• RCLK is inverted twice to reduce skew and to
ensure the required delay of
10 to 40ns
from the time of IRXC goes inactive (high)
to ICRS go inactive (end of packet
receive) for the 82586.
• AX is resynchronized with RCLK to become
RXD
• RENA is inverted and delayed for ICRS. A load
capacitance is added to increasethe mini-
mum
delay of the SIA's RENA with
respect to the last data
bit.
• CLSN is inverted for ICDT and also enables the
ICRS. Intel's 586 requires ICRS active
with
ICDT.
• Modified RCLK (M-RCLK) is used to reassert
RENA asynchronously
as required by the
82586 at the end of packet. Start of
packet synchronization has no problem.
• CLSN active or RENA inactive disable Receive
path to RXD.
Note: The inverters must have fast and symmetrical rise
and fall time. The Am2965 meets these require-
ments
and outputs MOS compatible logic levels.

EDUCATIONAL SUPPORT
1. E7900B Understanding and
Implementing Local Networks
This 2-day lecture and laboratory course covers the
AMD EthernetlCheapernet family as well as devices
(Am7960, Am7968/9, etc.) useful
in implementing other
forms
of computer networks. A companion course,
E7900A, covers
AMD devices more oriented toward the
telecommunications market (PABX, ISDN, etc.). Both
classes are scheduled throughout the year or, on spe-
cial request, at customer sites.
E7900B introduces those unfamiliar with networks to
the basic concepts and historical developments that
have led to the various types of computer networks now
available (Ethernet, Starlan, etc.). This allows the stu-
dent to understand the reasons why different network
forms can exist and where
each has merit in particular
applications.
The class then explains international standards (ISO),
completed or now
in progress, that are relevant to AMD
products now available (Ethernet, etc.) or soon to be
available (Starlan, FDDI, etc.). Generally related
devices (encryption, data compression, etc.) are out-
lined to provide
an overall system-application view. This
constitutes the class' first
day.
The second day covers the AMD Am7900 Family in
detail, including work with the Am7990 Ether-
net/Cheapernet evaluation board. Programming and
application details are discussed, from the bit level to
typical Data-Link Layer software, as used in the
Am7990T, PC-Turbo Evaluation Board.
