DDS Signal Generator Module Development Board Key benefits - Flexible multiwave output: delivers 2 sine waves and 2 square waves. Frequency range is 0-40 MHz for the AD9850 path and 0-1 MHz for the square wave. If you operate beyond 20-30 MHz, harmonics rise and the waveform may become less pure; a 70 MHz low-pass filter improves the signal-to-noise ratio. - Precise amplitude and timing control: a DAC reference pin enables easy adjustment of output amplitude. The duty cycle of the square waveform is adjustable with a trim resistor, allowing you to tailor signals for your application. - Versatile input and clock options: the AD9850 version uses a 125 MHz active oscillator, the AD9851 version uses a 30 MHz oscillator. The module supports both parallel and serial data input. - Compact footprint: dimensions are 5 cm x 2.6 cm, making it space-efficient for crowded test benches and portable setups. What makes it stand out - Combines multiple waveform outputs, flexible data input, and adjustable amplitude/duty cycle in a small, easy-to-integrate package. - Suitable for precise waveform synthesis in compact hardware projects and lab environments.
