DDS-25 Direct Digital Synthesizer 0-10 MHz Module 7 dB 220-225 MHzThe DDS 25 is a small (0. 52" X 1. 1") PCB module that contains an Analog Devices AD9833 DDS chip, a 25 MHz 3. 3V oscillator and associated bypass caps. The purpose of the module is to make DDS technology available to experimenters who do not want to use surface mount components to access this technology. The module is assembled on a 0. 032" double sided PCB with solder mask and silkscreen on both sides. The interface is a row of pads on 0. 1" centers
