If I use the integreted PLL, the noise from it is always more than -100dBc/Hz when it works at 5GHz. Could you introduce some special PLL with low noise?
I want to desgin a singal source that outputs 5GHz with 116dBc/Hz@10kHz. But it is difficult to reach the target by integrated PLL. Could someone give me some advices to get the target?
Thank you!
My output frequency are 102.4±0.512MHz. I connect a 1:1 transformer the to IOUT and /IOUT pins, and the secondary port of the transformer is the utput.
Should I need a 100ohm resistor between the output pin and GND, then connect to the filter?
Thank you!
Thank you for your reply.
Can you tell me more clearly what the "voltage compiliance" mean? What voltage it refer? The filter just can fliter the signal of the stopband, And the spur in the passband how to reduce it by the output circuit?
The a good filter is too difficuit to design...
I uesed AD9956 to make a circuit, and the spur of the signal outputing from AD9956 is bad. Could anyone can help me reduce the spur? Please tell me what I can do for the better spur and phase noise. Thanks!
