Analog DevicesAD9912A/PCBZ

The AD9912 evaluation board is an evaluation platform for the AD9912 direct digital synthesizer (DDS). It easily connects to a host computer via a USB interface and allows easy access to all AD9912 features via the Windows®-based evaluation software and graphical user interface.

This document provides instructions for the setup and installa-tion of the board and software and includes a description of the various software menus and hardware connections. Additional evaluation board details are available in the AD9912 evaluation board schematics on the included CD-ROM.

This document covers both Revision A and Revision B of the AD9912 evaluation board. The two versions differ in that Revision B has a convenient connection for a 1 kΩ pull-down resistor on the loop filter pin, whereas Revision A does not.

The AD9912/PCBZ operates over an industrial temperature range, spanning −40°C to +85°C.
