Using the AD9832 Evaluation Board
The AD9832 Evaluation kit is a test system designed to simplify
the evaluation of the AD9832. Provisions to control the AD9832
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 and gives information on
operating the evaluation board.
Prototyping Area
An area is available on the evaluation board for the user to 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 to be used in the final application.

XO vs. External Clock
The AD9832 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, if required, an external
CMOS clock connected to the part.
Power Supply
Power to the AD9832 Evaluation Board must be provided ex-
ternally through the pin connections. The power leads should be
twisted to reduce ground loops.
