GENERAL DESCRIPTION

This document serves as a guide to the setup and use of the
AD9959 evaluation board. The AD9959 is a multichannel
frequency synthesizer that incorporates four synchronous direct
digital synthesis (DDS) cores with many user-programmable
functions.
The evaluation board software provides a graphical user
interface for easy communication with the device along with
many user-friendly features such as the "mouse-over effect. "
Many elements of the software can be clarified by placing your
mouse over the element. Figure 19 shows how this feature
works when users place their mouse over the Ref Clock box.
This document is intended for use in conjunction with the
AD9959 data sheet, which is available from Analog Devices at
