EVALUATION BOARD
The AD9838 evaluation board allows designers to evaluate the
high performance AD9838 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 SDP board is based on the Blackfin
ADSP-BF527 processor with USB connectivity to the PC
through a USB 2.0 high speed port. For more information,
see the SDP board product page.
Note that the SDP board is sold separately from the AD9838
evaluation board.
AD9838 TO SPORT INTERFACE
The Analog Devices SDP board has a SPORT serial port that is
used to control the serial inputs to the AD9838. The connections
are shown in Figure 31.

EVALUATION KIT
The DDS evaluation kit includes a populated, tested AD9838
printed circuit board (PCB). The schematics of the evaluation
The software provided in the evaluation kit allows the user to
easily program the AD9838 (see Figure 32). 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.
More information about the evaluation software is available on
the software CD and on the AD9838 product page.

CRYSTAL OSCILLATOR VS. EXTERNAL CLOCK
The AD9838 can operate with master clocks up to 16 MHz.
A 16 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:
AEL 301-Series oscillators, AEL Crystals
SG-310SCN oscillators, Epson Electronics
POWER SUPPLY
Power to the AD9838 evaluation board can be provided from
the USB connector or externally through pin connections. The
power leads should be twisted to reduce ground loops.
