This module is based on the ADS9850 integrated circuit by Analog Devices. It is a full 125MHz CMOS DDS synthesizer. The AD9850 is a highly integrated device that uses advanced DDS technology coupled with an internal high speed, high performance, D/A converter and comparator, to form a complete digitally programmable frequency synthesizer and clock generator. The module is a fully functional device. You will only need to add power and control signals to operate this module.
