EVALUATING THE AD9653/AD9253/AD9633
ANALOG-TO-DIGITAL CONVERTERS

Preface

This user guide describes the 

AD9653

AD9253

 and 

AD9633

 evaluation boards, 

AD9653-125EBZ

,

AD9253-125EBZ

 and 

AD9633-125EBZ

, which provide all of the support circuitry required to operate

these parts in their various modes and configurations. The application software used to interface with
the devices is also described.

The 

AD9653

 

AD9253

 and 

AD9633

 data sheets provide additional information and should be consulted

when using the evaluation board. All documents and software tools are available at
