EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
This user guide describes the evaluation board for the
AD2S1200 and the AD2S1205, which are 12-bit resolution
tracking resolver-to-digital converters.
The AD2S1200 and the AD2S1205 integrate an on-chip
programmable sinusoidal oscillator that provides sine wave
excitation for resolvers.
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.
On-chip fault detection detects loss of resolver signals, out of
range input signals, input signal mismatch, and loss of position
tracking.
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.
HARDWARE LINK OPTIONS
The function of the link options are described in Ta ble 2. The
default setup is configured to operate the board with the mains
power supply adapter and to interface to the EVA L-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.
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 E VA L -SDP-CB1Z board.
When using this evaluation board with the E VA L -SDP-CB1Z
board, it is necessary to power the board through the J702
connector. The V
CCY for the ADG3304 and ADG3308 level
translator devices are sourced from the EVAL -SDP-CB1Z board.
In standalone configuration, it is possible to power the
evaluation board through external power supplies via the
relevant screw terminal connectors.
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 AV
DVDD input to supply the AD2S1200/AD2S1205 DV
DD pin. In addition, 5 V must be connected to the
DD pin.
12 V must be connected to the +12 V connector to supply the
excitation buffer circuitry.
Each supply is decoupled on this board using 10 µF tantalum
and 10 nF multilayer ceramic capacitors.
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.
