LMX2571: Regarding R42 and R41 settings

Hiroshi Akamatsu

Part Number: LMX2571

When setting R42 and R1 to change EXTVCO_CP_IDN and EXTVCO_CP_IUP2 value,

Is R0 writing required after R42, R41?

Sorry for my mistake.

Hi Akamatsu-san,

No, there is no vco calibration with external vco, no programming of R0 is required in this case.
