Other Parts Discussed in Thread: LMX2820
Tool/software:
Dear Forum and Support teams,
I would like to inquire about an issue related to fractional spurious observed in the LMX2820.
We measured the spurious of two LMX2820 devices under identical control conditions. Both devices use exactly the same loop filter components.
The attached images show the measurement results.
While most of the fractional spurs appear at similar levels in both devices, we observed a significant difference in the power level of the spur occurring at a 0.8 MHz offset. This particular spur is much stronger in one device compared to the other.
Could you please advise on the possible causes of this discrepancy?
Thank you for your support.
Best regards,
Takamasa
