DDS Signal Generator Development Board

AD9850/AD9851

Warm Tip: Spot is AD9850!
Compared with similar products, the appearance layout is not only exquisite, but also full patch processing, stable and reliable performance, send a complete set of development information, schematic diagram, procedures, instructions and so on.
Main functional characteristics
* Module can output sine wave and square wave, 2 sine wave and 2 square wave:
AD9850:0-40MHz
AD9851:0-70MHz
(The harmonics are getting bigger and bigger after the frequency is 20-30 MHz, and the waveforms are getting dirtier and dirtier.)
Fang Bo: 0-1MHz;
* 70MHz low-pass filter is used to make the SN ratio of waveform better.
* The pin (PIN12) which generates DA benchmark is introduced to facilitate the application of amplitude adjustment of output waveform.
* The reference input voltage of the comparator is generated by a variable resistance, which can be adjusted to obtain different duty cycle square waves.
* AD9850 module uses 125MHz active crystal oscillator, AD9851 module uses 30MHZ active crystal oscillator;
 
Main differences between AD9850 and AD9851
* The highest clock frequency of AD9850 is 125 MHz and that of AD9851 is 180 MHz. The highest output frequency of AD9851 is higher than that of AD9850.
* AD9850 has no 6-fold frequency, AD9851 has.
