EVALUATION BOARD
The EVAL-AD5543/EVAL-AD5553 is used in conjunction with
an SDP1Z system development platform board available from
Analog Devices, which is purchased separately from the
evaluation board. The USB-to-SPI communication to the
AD5543 is completed using this Blackfin-based development
board. The software offers a waveform generator.
SYSTEM DEVELOPMENT PLATFORM
The system development platform (SDP) is a hardware and
software evaluation tool for use in conjunction with product
evaluation boards. The SDP board is based on the Blackfin
BF527 processor with USB connectivity to the PC through a
USB 2.0 high speed port. For more information about this
device, see the system development platform web page
.
AD5543/AD5553 TO SPORT INTERFACE
The Analog Devices SDP has one SPORT serial port. The
SPORT interface is used to control the AD5543/AD5553,
allowing clock frequencies up to 30 MHz.

WAVEFORM GENERATOR
The evaluation board software offers a waveform generator to
show every change introduced and transmitted to the output.
OPERATING THE EVALUATION BOARD
The evaluation board requires ±12 V and +5 V supplies. The
+12 V V
DD
and V
SS
are used to power the output amplifier, while
the +5 V is used to power the DAC (V
DD1
).
