Part Number: LMX2820
Other Parts Discussed in Thread: LMX2594,

Hello team,

Do you have a plan to collect phase noise vs. charge pump information like HMC704 datasheet figure11 and figure12?

Taketo-san,

We do plan to do this, but don't have this data yet. I do not expect the PLL phase noise metrics to vary too much with the charge pump current. I say this because the LMX2820 charge pump has many similarities with the LMX2594 charge pump and the noise metrics of that charge pump did not vary much over charge pump current.

Regards,

Dean

Hello Dean-san,

I understand you have the plan. I would appreciate if you could let me know once you took the data.
