  • RE: LMX2594: maximum slew rate for ramping without calibration

    Noel, thanks again. I did not know about PLL Sim and will check it out.

    Effectively, the slew rate is about 6 MHz/us, because the 100 MHz change

    is finished after about 16 us.

    Noel, thanks for your answer.

    So if RAMPx_LEN= 1 (which is not forbidden), with my example the slew rate

    (the slope of the frequency ramp) is 10 GHz/us= 10000 MHz/us. Can the

  • LMX2594: maximum slew rate for ramping without calibration

    Part Number: LMX2594

    Does this mean we get in this small time a nice linear ramp with

    a very high frequency slew rate?

    E.g., if fpd= 100 MHz and the ramp is from 14 to 14.1 GHz (inside
