Part Number: LMX2531 I am using the part LMX2531LQ2570E in my design.
What does NOPB in the suffix of part number mean?
What are the loop filter values to generate 1290 MHz?
Part Number: LMX25311910EVAL None of my computers have a parallel port. How does one program this port with the parallel cable that comes with the EVM? Is there a better User's Guide than the one that comes with the EVM?

Part Number: LMX2531 Other Parts Discussed in Thread: CODELOADER I m programming LMX2531LQ1570E through an FPGA for 1600 MHz. I have composed the registers values from codeloader software. But when I configure the LD pin as digital logic high or low it…
Part Number: LMX25311570EVAL Hi all,
Recently I tried to measure the tuning voltage of this evaluation board on Vtune pin.
And when I switch the output frequency from 1620MHz to 1616MHz, the result is shown below.
To my knowledge, when the tuning voltage…
Dean,
Sorry that my last question seems to be ambiguous.
Just want to know when the amplitude setting is changed, which part of the LMX2531 will be influenced?
Does the word "amplitude calibration" mean that finding the optimal Q factor?
Thank…
Part Number: LMX2531 Hi guys,
You already helped me out on this thread , I have a follow up question.
The LMX2531 saves its previous settings through a hard reset of the CE pin, can you guys give any information about the latency between the moment CE…
Part Number: LMX2531 Hi,
My cutomer is using LMX2531LQ2570E. He has issue of output clock frequency fluctuation. Please see the below picture. The output frequency of LMX2531 fluctuates every 70 sec.
What is the cause of this issue? Could you give advice…
