LMX2571: external VCO mode

Part Number: LMX2571

Tool/software:

Hi Team,

1. For the 5V power supply of Vcc, if the power supply voltage is lower than 5V, for example, around 4.3V, can the charge pump work normally? Which spec will be affected?

2. In external VCO mode, when switching the f1 and f2 frequencies through the register, will the charge pump stop working during the switching process?

BR

    Hi Adrian,

    I assume you are referring to VcpExt, which could be anything between 3.3V and 5V. 

    Charge pump will not stop working during f1 f2 switching.
