EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
The AD2S1200 and the AD2S1205 integrate an on-chip
programmable sinusoidal oscillator that provides sine wave
excitation for resolvers.
This evaluation board comes with a wall-mountable switching
power supply that provides a 9 V dc output. Connect the supply
to a 100 V to 240 V ac wall outlet at 50 Hz to 60 Hz. The output
from the supply is provided through a 2.0 mm inner diameter
jack that connects to the evaluation board at J702. The 9 V
supply is connected to the various on-board power management devices that supply the correct bias to each of the various
sections on the board and the EVAL-SDP-CB1Z board.
The 12-bit angular position and velocity data is accessed via
either a 12-bit parallel port or a 3-wire serial interface. On-chip
incremental encoder emulation with direction output is also
available for positional data.
When using this evaluation board with the EVAL-SDP-CB1Z
board, it is necessary to power the board through the J702
connector. The VCCY for the ADG3304 and ADG3308 level
translator devices are sourced from the EVAL-SDP-CB1Z board.
On-chip fault detection detects loss of resolver signals, out of
range input signals, input signal mismatch, and loss of position
tracking.
In standalone configuration, it is possible to power the
evaluation board through external power supplies via the
relevant screw terminal connectors.
Complete specifications for the AD2S1200 and the AD2S1205
are provided in the AD2S1200 and the AD2S1205 data sheets,
available from Analog Devices, which should be consulted in
conjunction with this user guide when using the evaluation
board. Full details on the EVAL-SDP-CB1Z are available on the
Analog Devices website.
If the evaluation board is used without the 9 V adapter, 5 V
must be connected to the AVDD input to supply the AD2S1200/
AD2S1205 AVDD pin. In addition, 5 V must be connected to the
DVDD input to supply the AD2S1200/AD2S1205 DVDD pin.
12 V must be connected to the +12 V connector to supply the
excitation buffer circuitry.
HARDWARE LINK OPTIONS
Each supply is decoupled on this board using 10 µF tantalum
and 10 nF multilayer ceramic capacitors.
This user guide describes the evaluation board for the
AD2S1200 and the AD2S1205, which are 12-bit resolution
tracking resolver-to-digital converters.
The function of the link options are described in Table 2. The
default setup is configured to operate the board with the mains
power supply adapter and to interface to the EVAL-SDP-CB1Z
board via the parallel interface.
It is also possible to operate the board in standalone mode when
interfacing to a user defined system. The evaluation board can
be configured to operate in standalone serial or parallel mode
by setting the necessary link options. Angular positional data
can also be determined by interfacing with the encoder outputs.
POWER SUPPLIES
Care should be taken before applying power and signals to the
evaluation board to ensure that all link positions are as per the
required operating mode. See Table 2 for the complete list of
link options.
Extensive ground planes are used on this board to minimize the
effect of high frequency noise interference. There are two main
ground planes, AGND and DGND. These are connected at one
location close to the AD2S1200/AD2S1205.

STOP. Stops the program.
Reoccurring Acquisition. Repeats single acquisition until the
button is released (normal mode).
Flash LED. Causes the orange LED1A on the SDP board to
flash, which can be a useful debugging tool.
Number of Samples. Selects the number of samples to be
completed in a single acquisition.
ON/OFF. Enables or disables the histogram option. (This button
appears on the Histogram Position and Histogram Velocity
tabs only.)
Data Capture Display
In the data capture display, you can select the format in which
to view the position and velocity conversion results. The position data can be displayed in digital output code format or in
degrees. The velocity data can be displayed in digital output
code format or in rotations per second (RPS). The desired
display options are selected by clicking on the Acquisition
(Codes), Acquisition (Degrees/RPS), Histogram Position,
and Histogram Velocity tabs.
The Histogram Position tab displays the histogram of the position conversion results taken in normal mode of the resolver
connected to the EVAL-AD2S1200/05SDZ board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Histogram Velocity Tab
The Histogram Velocity tab displays the histogram of the velocity
conversion results taken in normal mode of the resolver connected to the EVAL-AD2S1200/05SDZ board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
Within any of the chart panels, the tools shown in Figure 15
allow user control of the different chart displays.

DATA CAPTURE
To initiate conversions and to capture the sample data, you must
click the Single Acquisition or the Reoccurring Acquisition
button.
When the Single Acquisition button is clicked, the software
instructs the EVAL-SDP-CB1Z to read back the conversion
results from the EVAL-AD2S1200/05SDZ board. The number
of samples is selected via the Number of Samples box. After
each conversion, data from the AD2S120x is written to external
memory on the EVAL-SDP-CB1Z. The required set of samples
is uploaded through the USB port to the PC when all conversions are completed.
When you click the Reoccurring Acquisition button, the software
instructs the EVAL-SDP-CB1Z to read back the conversion
results from the EVAL-AD2S1200/05SDZ board in a repeating
loop. The number of samples is selected via the Number of
Samples box. After each conversion, data from the AD2S120x is
written to external memory on the EVAL-SDP-CB1Z. The
required set of samples is uploaded through the USB port to the
PC when all the conversions are completed. If the Reoccurring
Acquisition button is not clicked again to release the loop, the
conversion loop repeats. While the data is being uploaded to the
PC, the AD2S120x device is not converting; therefore, there may
be a time delay between two blocks of samples.
In single acquisition and reoccurring acquisition mode, the data
is displayed on the data capture display. The data is displayed on
the Acquisition (Codes), Acquisition (Degrees/RPS),
Histogram Position, and Histogram Velocity tabs.
Figure 16 shows a typical data capture. Both position and velocity
data results are presented in the data capture display. Additionally,
the following data is displayed:
