DDS signal generation technology in compact form The AD9850 development board with multiwave capability Ref: 3773 Description

1.Improved waveform signaltonoise ratioTo improve the quality of the waveform, this module is equipped with a 70MHz lowpass filter, which results in a better signaltonoise ratio. 2.Amplitude adjustment with pin accessThe module provides access to the pin (PIN) that generates the DA reference. This enables convenient adjustment of the output waveform amplitude to specific application requirements. 3.Flexible square wave duty cycleBy adjusting the variable resistor, the reference input voltage of the comparator can be changed, allowing for various duty cycles of the square wave output. 4.Stable and precise oscillatorThe AD9850 module uses an active oscillator with 125 MHz, while the AD9851 module uses an active oscillator with 30 MHz. This ensures stable and accurate frequency generation. 5.SpecificationFrequency range for AD9850: 040 MHz. 2. Output: 2 sine waves and 2 square waves 3. Harmonic distortion may increase over 2030 MHz. 4. Square wave frequency: 01 MHz. 5. Improved waveform signaltonoise ratio with a 70 MHz lowpass filter. 6. Allows selection between parallel and serial data input. 7. Accessible pin (PIN) for amplitude adjustment. 8. Duty cycle of the square wave can be adjusted via the variable resistor. 9. Modules feature stable 125 MHz and 30 MHz active oscillators, respectively. 10. Dimensions: 4.5 x 2.6 cm.
