EVALUATION BOARD
The AD9833 evaluation board allows designers to evaluate the
high performance AD9833 DDS modulator with a minimum
of effort.
SYSTEM DEMONSTRATION PLATFORM
The system demonstration platform (SDP) is a hardware and
software evaluation tool for use in conjunction with product
evaluation boards. The
ADSP-BF527
through a USB 2.0 high speed port. For more information
about the SDP board, see the SDP board product page.
Note that the SDP board is sold separately from the AD9833
evaluation board.
AD9833 TO SPORT INTERFACE
The Analog Devices SDP board has a SPORT serial port that is
used to control the serial inputs to the AD9833. The connections
are shown in Figure 32.
EVALUATION KIT
The DDS evaluation kit includes a populated, tested AD9833
printed circuit board (PCB). The schematics of the evaluation
board are shown in Figure 34 and Figure 35.
The software provided in the evaluation kit allows the user to
easily program the AD9833 (see Figure 33). The evaluation soft-
ware runs on any IBM-compatible PC with Microsoft® Windows®
software installed (including Windows 7). The software is com-
patible with both 32-bit and 64-bit operating systems.

the software CD and on the
CRYSTAL OSCILLATOR VS. EXTERNAL CLOCK
The AD9833 can operate with master clocks up to 25 MHz.
A 25 MHz oscillator is included on the evaluation board. This
oscillator can be removed and, if required, an external CMOS
clock can be connected to the part. Options for the general
oscillator include the following:
•
•
POWER SUPPLY
Power to the AD9833 evaluation board can be provided from
the USB connector or externally through pin connections. The
power leads should be twisted to reduce ground loops.
