LMX2820: Fast locking scheme when changing the VCO frequency

Hi Team,

Customer want to quick lock the lmx2820 PLL when changing the VCO frequency, and they want the re-lock time less than 50us.

Customer are concerned that after changing the VCO frequency and SPI configuration time, the re-lock time will exceed 50us.

Do we have any methods to support this kind of use case?

Thanks,

Adrian
