- DDS Signal Generator Module Development Board: This versatile module delivers reliable performance by outputting 2 sine waves and 2 square waves. The frequency range is 0-40 MHz for sine waves (AD9850) and 0-1 MHz for square waves, meeting various signal generation needs. However, expect some harmonics and waveform distortion beyond 20-30 MHz. Utilizing a 70 MHz low-pass filter enhances the signal-to-noise ratio for clearer waveforms. - Easy Amplitude and Duty Cycle Adjustments: The module features a dedicated pin for generating the DA reference, allowing for convenient adjustment of the output waveform's amplitude. Additionally, you can modify the duty cycle of the square wave using a variable resistor, offering flexibility for specific applications. - Advanced Oscillator and Input Options: The AD9850 model is equipped with a 125 MHz active oscillator, while the AD9851 features a 30 MHz active oscillator. This design supports both parallel and serial data input, catering to different project requirements. - Compact Form Factor: Measuring just 5cm x 2.6cm, this module is designed for efficient use of space, making it ideal for compact projects or setups where real estate is limited. - Application Scenarios: 1. Ideal for semiconductor testing and evaluation setups requiring precise sine and square waves at varying frequencies. 2. Useful in audio signal generation applications where varying amplitudes and duty cycles are needed for sound design and testing. 3. A great choice for communication systems that need clean waveforms for modulation and demodulation processes. This module blends functionality and convenience, making it a reliable tool for engineers and hobbyists alike.
