AD9850 DDS Signal Generator Module with 125MHz Oscillator, Compatible with AD9851

Signal Output and Control This DDS signal generator module provides two sine waves and two square waves, giving you flexible waveform options for your projects. The sine wave covers a frequency range from 0 to 40MHz, while the square wave operates from 0 to 1MHz, allowing you to select the required setting for your application. You can adjust the amplitude via the DA reference pin and modify the duty cycle using a variable resistance, offering direct control over the output. Signal Quality and Connectivity A 70 MHz low-pass filter is used to improve the signal-to-noise ratio of the waveform. The module is built around a 125MHz active oscillator and supports both parallel and serial data input, making it practical to connect with a variety of microcontrollers. Compatibility Compatible with the AD9851 module. What to Know Before Use The module measures 5cm x 2.6cm. Please note that harmonics increase and the waveform becomes less pure when operating above 20-30 MHz.
