• ADF4111 Initialization

    I'm hoping that someone can confirm my initialization procedure for the ADF4111.  I've attached two different methods.  One is by using the CE pin and the other is via the Initialization latch.  I can't get it to lock and there absolutely 0V on the…

  • RE: Obsolete PLL Replacement

    Unfortunately, we have no PLLs that are drop-in replacements for that part.

    You may be interested in similar PLLs. Possibly the ADF4117 or ADF4111.

    Hi,

    I wish to know to know the performance of ADF4111 PLL with respect to Clipped sine wave reference vs pure sine wave reference. What is the differences in terms of performance like Phase noise, harmonics with respect to above two Ref inputs. Please…

  • RE: ADF4110 Prescaler

    Hi, at new PCB a make this prescaler for 500 / 1000

    ADF4111 work from 137.5MHz(may be lower, but a can't check) to 1.4-1.-8GHz while the upper limit of her 1.2GHz

    ADF4107 work up to 7 - 7.5 GHz

    Work with: ADF4106, ADF4107, ADF4110, ADF4111, ADF412…

  • ADIsimPLL : Crystek VCO with ADF4111 Question

    Hello,

    I am attempting to simulate a design using a Crystek VCO (CV55CL0120-0130) and an ADF4111. I would like a single output frequency of 125MHz using a reference of 44.8MHz. However, no matter what I seem to use for the parameters, ADIsimPLL gives…

  • RE: ADF4116 and "Delay" and "Sync" bits

    That is a mistake in the software. The Sync and Delay bits should actually be hidden. They apply to the ADF4110, ADF4111, ADF4112, and ADF4113 which use the same piece of evaluation board control software.

    Just set them to 0 and I'll removed them in…

  • RE: Using N, R divider for frequency division

    Yes, the input sensitivity and slew rate. You will need to scale down the amplitude. You can do this by placing a resistor (~100 ohm) between the two differential signals. Both signals should have have a series capacitor. See image.

    You will need…
