Produktbeskrivning
The DDS module is base on AD9850 which is provided by ADI Company and frequently used in many DDS modules.The chip provide 0-40MHz generation capability,the AD9850's innovative high speed DDS core provides a 32-bit frequency tuning word, which results in an output tuning resolution of 0.0291 Hz for a 125 MHz reference clock input.
This module provide you a ready made hardware and you can use serial or parallell pins on board to control the AD9850 for different frequency out put. The duty cycle can be adjusted by a variable resistor - which controls the reference voltage level of the comparator.
Features
2 channels square wave output and 2 channels sine wave output
Sine wave: 0-40MHz ; Square wave: 0-1MHz
Using 70MHz low pass filter improves the waveform's S/N ratio
Parallel and Seiral data bus selction
Duty cycle adjustable - Comparator reference input voltage generated by the variable resistor
DA reference Pin12 elicit, easy adjustment of output amplitude
Size: 42 x 30 x 1.6 mm
