HARDWARE DESCRIPTION
The Evaluation Board Controller is based around an
ADSP-2189M Digital Signal Processor (DSP). The DSP
runs from a 20MHz crystal and an on-chip clock doubler
gives an instruction speed of 40MIPs. The DSP features
32Kwords of Internal Program Ram and 48Kwords of
internal Data RAM. The Data RAM is supplemented with
64Kwords of external data RAM. The DSP also provides
two Serial Ports (SPORTs) which have a maximum ouput
serial clock rate of 20MHz. Both SPORTs are available
on the 96way edge connector as is a section of the parallel
Data and Address bus.
To facilate operation of both 3V and 5V evaluation
boards all logic signal are equiped with level translators.
For 3V devices no level translation is required (since the
DSP operates from 3V) so the level translators act as
closed switches. For 5V devices all logic 1 signals coming
from the DSP are level translated to 5V. 5V logic signals
coming from the device under test are translated to 3V by
the translators before reaching the DSP.
Communications
The Evaluation Board Controller allows a user to gather a
large number of samples from an evaluation board and
upload them the a PC for analysis. The Evaluation Board
Controller uses a high-speed interface based around the
PCs Printer Port. As the port is used both for sending and
receiving data it must have bidirectional capability. Most
PCs (particularly the Pentium class) have this facility as
standard but it is possible to check in the PCs BIOS. How
the BIOS is viewed depends on the make of PC being
used but typical methods are pressing CTRL, ALT and
ENTER during power up. The user should consult the
operating manual of their PC for further details. Suitable
printer port types may be described as Bidirectional,PS/2,
EPP or ECP.
Power Supplies
The Evaluation Board Controller has its own on-board
power supplies which are derived from a 12VAC power
supply with a 1A current capability. These supplies are
used to supply the current for the Evaluation Board Controller itself as well as that required for the evaluation
board and are available from Analog Devices using the
order numbers given above. The power supplies which go
to the evaluation board via the edge connector are fully
controllable by the software supplied. The Evaluation
Board Controller can provide ±3V or ±5V analog supplies
as well as a +3V or +5V digital supply. There is also a
±12V / ±15V supply for powering op-amps etc. The value
of the supplies are selected by jumpers LK1 and LK2.
Table I below lists the power supplies available while
Table II shows the jumper setting for the ±12V / ±15V
supplies.

SETUP PROCEDURE
Hardware
The Evaluation Board Controller is part of a self-contained system which allows a user to quickly and easily
evaluate/demonstrate the functions and performance of a
particular Analog Devices Precision Converter. All evaluation boards which are compatible with the Evaluation
Board Controller have the designation CB in their order
code. For example the order code for an evaluation board
based around the AD7476 would be EVAL-AD7476CB.
The evaluation board plugs directly into the 96 way
connector on the Evaluation Board Controller. The
Evaluation Board Controller is powered from a standard
12VAC power supply. The power supply is available from
Analog Devices as an accessory. The power supplies are
also available for other suppliers such as Digikey (US)
and Campbel Collins (UK).
A Centronics printer port cable is supplied with the
Evaluation Board Controller kit enabling communication
between the Evaluation Board Controller and the PC.
Software
The Evaluation Board Controller come supplied with a
CD which contains software for previously released evaluation boards. Therefore if the user has an evaluation board
which was compatible with the previous version of the
Controller (Eval Control Board) they will be able to use
the Evaluation Board Controller as well.
When the user purchases an new evaluation board kit it
will contain all the software necessary to operate that particular evaluation board. The most up-to-date evaluation
software is always available on the Analog Devices web
site (www.analog.com). The documentation which is supplied with the evaluation board also contains information
about installing the software as well as a detailed description of the evaluation board and a data sheet for the device
in question.
All software supplied for the Evaluation Board Controller
and evaluation boards comes on a CD ROM. When the
CD is inserted into the PC an installation program will
automatically begin. This program will install the evaluation software onto the users machineand will also install
the Technical Note for the evaluation board as well as the
Data Sheet for the device in questions. All literature on

Evaluation Board Controller
Figure 1. Evaluation Board Controller Main Screen
SOFTWARE DESCRIPTION
The software which controls the Evaluation Board Controller and hence the evaluation board has three main
screens. The screen shown in Figure 1 shows the screen
which appears when the software is run. The main function of this screen is to allow the user to read a predetermined number of samples from the evaluation board and
display them in both the time and frequency domain. The
screen can be divided into 3 sections. The upper third of
the screen contains the control buttons, the menu bar and
various status windows. The control buttons allow the user
to enter the setup menu, take samples and get information
about the software. The menu bar allows the user to select
which printer port is to be used to control the Evaluation
Board Controller, load and save data etc. The status windows indicate the setup of the evaluation board/device,
number of samples taken and any information/error messages that are generated.
The middle third of the screen is a Digital Storage Oscilloscope (DSO). When samples are uploaded from the
Evaluation Board Controller they are displayed here. The
samples can be displayed either as integer values or as
voltages (determined by the input range of the device in
question). Once samples have been displayed clicking at
any point in the graph will display the sample number and
value of the point directly beneath the cursor. Along the
axis of the graph are the "zoom handles". These allow the
user to zoom in and out to get a closer look at a particular
sample if required. When another set of samples is taken
the graph will attempt to display all values collected unless
the Hold Zoom check box is ticked. In this case the graph
will keep the same axis settings as for the previous set of
data samples. Additional check boxes are provided to give
the user control over the vertical and horizontal grids and
data points.
The lower third of the screen will show either a Fast
Fourier Transform (FFT) of the data or a Histogram
which shows the number of occurrances of each particular
code read back. The FFT (the default option) is typically
used when the user is concerned with examining an ADC's
performance in the frequency domain while the Histogram
will give an indication of the ADC's performance to DC
signals. The option displayed can be toggled by clicking
on the FFT Mode/Histogram Mode button in the top
right of the screen. Figure 2 shows how the main screen
looks when the Histogram Option is selected.

Setup Screen
The Setup Screen is responsible for allowing the user to
load a configuration file for the evaluation board. The
configuration file will give the software detailed information about the evaluation board and part connected to the
Evaluation Board Controller such as number of bits,
maximum sampling rate, power supply requirements etc.
The configuration file also tells the software the name of
the DSP program file which it should download to the
Evaluation Board Controller. These files are supplied by
Analog Devices with the evaluation board. Figure 3 shows
the Setup Screen.
Evaluation Board Controller and evaluation board should
be connected together (via the 96 way connector). The
power should be applied to the Evaluation Board Controller. At this stage the red LED should be flashing which
indicates that the Evaluation Board Controller is functional and ready to receive instructions. The software
which should have been installed should be loaded before
the printer port cable is connected between the Evaluation
Board Controller and the PC. This will ensure that the
printer port has been initialized properly. The printer port
cable can then be connected between the PC and the
Evaluation Board Controller.

the setup form. A window on the left of the setup form list
all the available configuration files. The configuration
files are text based files which contain information about
the particular evaluation board to be tested. The information will cover such things as the part name, number of
samples to be taken, default and maximum sampling frequency power supply settings etc. The configuration file
also contains the name of the DSP program file which is
to be downloaded to the Evaluation Board Controller.
The user should select the relevant configuration file and
click Load. The Evaluation Board Controller will be reset
and the DSP program will be downloaded. When the
download has been completed the power supply settings
indicated in the configuration file are set and the user may
hear some of the relays clicking. The pull-down menus
items such as number of samples and sampling frequency
will have been set to the default values specified by the
configuration file. The user is free to change these at will.
Once all the settings had been decided the user can click
Close to return to the main form.
Taking Samples
When the user clicks Sample the software will instruct the
Evaluation Board Controller to take the required number
of samples at the required frequency from the evaluation
board. These samples are then uploaded and displayed. An
FFT and Histogram are also calculated and displayed. If
the user clicks Cont Samp the software will repeat the
process indefinitely until the user clicks the button again.
While the software is continuously sampling data the other
control buttons are disabled.
MENU BAR ITEMS
The main screen of the Evaluation Board Controller contains a number of options available as pull-down menu
items. The functions of these are listed below.
File Menu:
Setup Menu: Selecting this option displays the Setup
Screen as shown in Figure 3.
Load Raw Data: Selecting this option allows the user to
load data which had been saved by the software during a
previous session.
Save Raw Data: Selecting this option allows the user to
save the current set of sample data points. The data can be
reloaded to the Evaluation Board Controller software at a
later date or can be used by other programs for further
analysis
Save Binary Data: Selecting this option allows the user to
save the current set of sample data points. The data is
saved in binary format as a text file. This method can be
useful for examining code flicker, looking for stuck bits
etc.
Save FFT Data: Selecting this option allows the user to
save the current set of FFT data points. FFT data cannot
be reloaded into the Evaluation Board Controller software
but can be loaded into other software packages for further
analysis.
Exit: Quits the program.
Other Buttons
The Reset button will cause the Evaluation Board Controller to perform a reset function. When this happens the
power supplies are turned off and the program in DSP
memory is lost. The user should repeat the setup instructions to download another program if required.
The Quit button will exit the software, the program running on the Evaluation Board Controller is not terminated.

Table IV. Troubleshooting guide
Symptom
Possible Cause
LED Not Flashing
No power is applied to the evaluation board. The evaluation board requires a 12V
AC supply.
No Communication between
PC and Evaluation Board.
There are a number of possible causes for a communications failure. These are listed
below.
1. Cable not connected or incorrect cable type. The cable should be a fully-populated
Centronics printer port cable.
2. Incorrect printer port. The evaluation board requires that the printer port has bidirectional capability. Acceptable types are PS/2, EPP and ECP.
3. Correct Printer Port but bidirectional capability not enabled. It is possible that a
bidirectional printer port can be set to be unidirectional mode in the PC BIOS.
The user should consult the PC manual for instructions on examining the BIOS
4. Incorrect Printer Port Address. There are three possible addresses for a printer
ports and the one fitted to a users PC may not be the same as the default address.
This can be changed using the Printer Port menu item.
The evaluation board being used with the Evaluation Board Controller may have the
links incorrectly set.
