Main functional features nbsp The module is capable of outputting sine waves and square waves with 2 sine waves and 2 square waves output nbsp nbsp AD9850 nbsp 040MHz nbsp nbsp AD9851 nbsp 070MHz nbsp nbsp After the frequency reaches 2030 MHz the harmonics become larger and the waveform becomes increasingly unclean nbsp nbsp Square wavenbsp nbsp 01MHz nbsp nbsp Using a 70MHz lowpass filter to improve the SN ratio of the waveform nbsp The pin PIN12 that generates the DA reference is led out making it convenient for amplitude adjustment applications of output waveforms nbsp nbsp The reference input voltage of the comparator is generated by a variable resistor and adjusting this resistor can obtain square waves with different duty cycles nbsp The AD9850 module uses a 125MHz active crystal oscillator while the AD9851 module uses a 30MHz active crystal oscillator The main difference between AD9850 and AD9851 is that The clock frequency of AD9850 is 125MHz and the clock frequency of AD9851 is 180MHz Output frequency
