DDS Signal Generator Module Development Board - Dual Wave Output: This module generates 2 sine waves and 2 square waves. It covers a frequency range of 0-40MHz for sine waves (AD9850) and 0-1MHz for square waves, ensuring versatility in signal generation. - Enhanced Signal Quality: While harmonics may increase and waveform purity may diminish above 20-30MHz, a built-in 70MHz low-pass filter significantly improves the signal-to-noise (SN) ratio, providing cleaner outputs. - Adjustable Amplitude and Duty Cycle: Easily modify the output waveform amplitude using a dedicated DA reference pin. The duty cycle of the square wave can be adjusted via variable resistance, allowing for precise control based on your project needs. - Versatile Oscillator Options: The module features a 125MHz active oscillator in the AD9850 variant and a 30MHz active oscillator in the AD9851 variant, accommodating different application requirements. It supports both parallel and serial data input, simplifying integration into existing systems. - Compact and Efficient Design: Measuring just 5cm x 2.6cm, this module is designed for minimal space usage, making it ideal for projects with limited real estate. Applications: 1. Signal Testing: Ideal for engineers and hobbyists needing to test circuit responses to different waveforms and frequencies. 2. Communication Systems: Useful in developing and testing RF communication systems where specific sine and square wave outputs are required. 3. Educational Projects: Great for students and educators in electronics labs for practical demonstrations of waveform generation and manipulation. This module is a reliable solution for generating high-quality signals with easy customization, perfect for a wide range of electronic applications.
