GENERAL DESCRIPTION
The AD9837 is a 16 MHz low power DDS device capable of
producing high performance sine and triangular outputs. It
also has an on-board comparator that allows a square wave to
be produced for clock generation. Consuming only 20 mW of
power at 3 V makes the AD9837 an ideal candidate for power-
sensitive applications.
The EVAL-AD9837SDZ board is used in conjunction with a
EVAL-SDP-CB1Z SDP board available from Analog Devices, Inc.
The USB-to-SPI communication to the AD9837 is completed
using this Blackfin®-based development board.
A high performance, on-board 16 MHz trimmed general oscillator
is available to use as the master clock for the AD9837 system.
Various links and SMB connectors are also available on the
EVAL-AD9837SDZ board to maximize usability.
Complete specifications for the AD9837 are provided in the
AD9837 data sheet, available from Analog Devices, and should
be consulted in conjunction with this user guide when using the
evaluation board.
