Two sine wave outputs and two square wave outputs. The module supports AD9850 (0-40 MHz) and AD9851 (0-70 MHz). Note: above 20-30 MHz the harmonics rise and the waveform becomes less clean. Square (rectangular) wave output is 0-1 MHz. Key benefits - Improved waveform quality: a 70 MHz low-pass filter enhances signal-to-noise ratio and overall waveform cleanliness. - Flexible amplitude control: a dedicated pin to generate the DA reference enables easy amplitude adjustment for different applications. - Adjustable duty cycle: a variable resistor on the comparator reference input allows tuning of the square wave duty cycle. - Stable oscillators: AD9850 module uses a 125 MHz active oscillator; AD9851 module uses a 30 MHz active oscillator for reliable performance. - Compact form factor: dimensions are 5 cm x 2.6 cm for easy integration into diverse projects.
