Can anyone please tell me what is the output of AD9525?
It is a square or sine wave?
As seen on the datasheet within the clock distribution section, it specifies that the output duty depends on a certain M divider. Since duty cycle is applicable to periodic pulses, it implies that the output of AD9525 is a square wave.
So can you please advice me what I should use so that i get sine wave for about 2 GHz from clock generator. I want atleast 3 output clock generator.
The output of the AD9525 is a square wave.
The ADF4360-2 can provide a 2GHz output, but I believe it has a square wave output, too.
A DDS would be your best candidate for providing a sinusoidal output. However, none of our DDS devices will directly yield a 2GHz output. The AD9914 can produce sinusoids up to 1.4GHz and operating the device in a super-Nyquist configuration would allow you to extract a 2GHz sinusoid (see AN-939 for a description of operating a DDS in a super-Nyquist configuration).
Another solution might be to use a device that generates a 2GHz square wave, but lowpass filter the output to pass only the fundamental frequency (2GHz in your case). The lowpass filter will strip off the harmonic content of the square wave leaving only the 2GHz fundamental sinusoid.
