Description
Sine Wave Square Wave High Frequency Generator Module AD9850 DDS Board AD9850 Signal Generator Module
Product Description
Feature
* The module can output sine wave and square wave, 2 sine wave and 2 square wave output. AD9850: 0-40MHz AD9851: 0-70MHz After the frequency is 20-30MHz, the harmonics will become larger and larger, and the waveform will become more and more unclean. Square wave: 0-1MHz * Adopt 70MHz low-pass filter to make the SN ratio of the waveform better * The pin (PIN12) that generates the DA reference is led out, which is convenient for the application of amplitude adjustment of the output waveform. * The voltage of the reference input terminal of the comparator is generated by a variable resistor, which can be adjusted to obtain different duty cycle square waves * AD9850 module adopts 125MHz active crystal oscillator, AD9851 module adopts 30MHz active crystal oscillator
