  • AD9522


    I'm currently attempting to use the AD9522 Eval to clock my AD9914 Eval. I am using the internal VCO of the AD9522 Eval, but when I externally measure the output signal of my AD9522 I see a different frequency from what the evaluation GUI is telling…

  • AD9522 Clock Synthesizer Issue


    I have been programming AD9522 at input frequency 10 MHz and required output frequency 100 MHz. As I am probing Lock Detect (LD) pin, I am getting glitches of about 250 ns at random intervals.

    In another case, I am programming AD9522 at input freq…

  • AD9522 separate power supply


    In the evaluation board for AD9522, separate power supplies are used for Vs and Vcp.

    Is it mandatory?

    Can I power both the supplies from a single LDO -  ADP3339.

  • AD9522-1 internal VCO problem


    I designed a PCB that includes an AD9522-1 that I intend to use for clock distribution. The supporting circuitry for the AD9522-1 is basically a copy of the AD9522/PCBZ Evaluation Board (which I also use to program the AD9522-1 in my design by means…

  • AD9522-1 REF IN Clock


    Looking for a support on AD9522-1 input reference clock.  We are using singled ended reference clock[one from FPGA, one from oscillator], with AC coupling and AD9522 internal DC offset is off.

    When we probed on the REF_IN pin, there is a -0.4V offset…

  • AD9522 PLL cann't be Locked

    Hi, appreciate your help first

        There are high speed AD, DA, FPGA, DSP and two Clock generation chip AD9522 on the board, one for AD and DA, one for FPGA MGT and DSP.

    The AD9522 schematics are attached as fpga.pdf, and the value of resistors and caps…
