Other Parts Discussed in Thread: LMX2594, LMK04832, LMX2582
Hi all,
Currently, we're testing LMX2594 and found that there are spurious at 1MHz offset,shown as Figure.1 .
We have tried to change charge pump current but spurious only shift not reduce.
Input reference is 122.88 MHz, phase detecter frequency is 245.76 Mhz and more detailed setting shown as Figure.2.
Please give us some advice about where these spurious come form and how to reduce them.
Thank you!
Best regards,
Alan
