AD9831 E valuation Board
T he AD9831 Evaluation Board allows designers to evaluate the
high performance AD9831 DDS Modulator with a minimum of
effort.
T o prove that this device will meet the user’s waveform synthe-
sis requirements, the user only requires a 3.3 V or 5 V power
supply, an IBM-compatible PC and a spectrum analyzer along
with the evaluation board. T he evaluation setup is shown
below.
T he DDS Evaluation kit includes a populated, tested AD9831
printed circuit board along with the software which controls the
AD9831 in a Windows environment.

Using the AD9831 E valuation Board
T he AD9831 Evaluation kit is a test system designed to simplify
the evaluation of the AD9831. Provisions to control the
AD9831 from the printer port of an IBM-compatible PC are
included along with the necessary software. An application note
is also available with the evaluation board which gives informa-
tion on operating the evaluation board.
Prototyping Area
An area is available on the evaluation board where the user can
add additional circuits to the evaluation test set. Users may
want to build custom analog filters for the output or add buffers
and operational amplifiers which are to be used in the final
application.
X O vs. E xternal Clock
T he AD9831 can operate with master clocks up to 25 MHz. A
25 MHz oscillator is included on the evaluation board. How-
ever, this oscillator can be removed and an external CMOS
clock connected to the part, if required.
Power Supply
Power to the AD9831 Evaluation Board must be provided ex-
ternally through the pin connections. T he power leads should
be twisted to reduce ground loops.
