AD9850 DDS Signal Generator Module Sine Wave Square Wave Generator Development Board Module
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 voltage of the reference input terminal of the comparator is generated by a variable resistor, and the square wave of different duty cycles can be obtained by adjusting the resistor;
*AD9850 module adopts 125MHz active crystal oscillator, AD9851 module adopts 30MHz active crystal oscillator;
The main difference between AD9850 and AD9851
*The AD9850 can be clocked up to 125MHz and the AD9851 can be clocked up to 180MHz. The output frequency of the AD9851 is higher than the AD9850.
*AD9850 does not have multiplier by 6, AD9851 does.
Dimensions: 25*45MM

How to choose the correct size:
Step 1 Please measure your foot length carefully.
Step 2 Please choose the correct size according to your foot length and chinese size.
For example, If your foot length is 255 mm , you should choose the size 8.
