    How to calculate the PLL locking time?

    Someone kowns how to calculate the PLL locking time give me some help, please. Paper or ebook, thanks.

    Looking for PPL which receives 74 Mhz

    Re: Help on PLL I think that imposible. the fraction_N PLL can not do that. Maybe you can use DDS to do it.

    Design a low phase noise frequency systhesizers

    Thank you for your reply! 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?

    Design a low phase noise frequency systhesizers

    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!

    how to wind inductance in nH?

    It is difficult to wind inductance in nH. A small wire has inductance in nH, but the Q is too low! Maybe buy the one you needed is better.

    How to reduce the spur of the DDS?

    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!

    How to reduce the spur of the DDS?

    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...

    How to reduce the spur of the DDS?

    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!
