• RFinput for ADF4154, ADF4156

    Hi,

    I'm a DFAE in Japan. The customer is thinking of adopting ADF4154 or ADF4156, but he wants to use the input frequency at 78MHz. In this case, is it possible to operate at the low frequency if the slew rate is kept at 400V / µs?

    Regards,

  • ADF4154 rev changes or errata?

    HEllo:

    My customer purchased some ADF4154 PLLs a while ago and performed exactly like the simulation.  Then they purchased a few more and

    all parts have higher phase noise on in-loop band and it seems the figure of merit of the new batch is much higher…

  • ADF4154, PC interface board microcontroller software

    Hello,

    My customer is asking if ADI can make the firmware available for the Cypress PSOC (CY7C68013) microcontroller that does the conversion from USB to serial that is on the ADF4154 PC interface board (parat number EVAL-SDP-CS1Z)?

    Thank you,

  • Replacing ADF4154 with ADF4151 to gain lock detect and fast-lock

    Hi,

    I have a current prototype design with a ADF4154, the ability to achieve quick settling (<20us) using the fast-lock feature is critical, for production I would like to add a lock detect indication and so am considering a replacement part.

    Is there a loop filter on your board? Are R1, R2, C1, C2 and C3 populated?

  • Q: What happens to the PLL when the REFIN is removed ?.

    All our Frequency Synthesizers parts can have the Reference (REFIN) signal removed, and unlock will result. Reconnecting REFIN will result in the part locking  to the correct frequency. ADF41xx parts will behave in this manner. Our Frequency Synthesizers…

  • RE: ADF4157 and ADIsimPLL

    Hi Tim,

    You're correct, It should be in the "speedup mode" drop down menu on the left of the screen and it's not there for either the ADF4154 or ADF4157 -- checked both.
