【AD9833をオーバー・クロックで使う】 abstract I will now attempt to overclock the DDS-IC AD9833. According to the datasheet, the upper clock limit of the AD9833 is 25MHz. My guess is that 25MHz is too low. In my tests, the AD9833 worked fine even with a clock of over 100MHz. I will get a clean 30MHz signal from the AD9833 DDS module.Now the $2 DDS module has a new value.
