AD9364 CP Ovrg/VCO Lock

Hi,

I am working on AD9364.  BBPLL VCO calibration and RF synthesizer charge pump calibration is done. But RF synthesizer VCO calibration is not done. The register 0x247 =0x40(PLL lock bit is 0 and the CP Ovrg Low  is 1). The register 0x287=0x80(PLL lock bit is 0 and the CP Org High  is 1)

 

1) Is CP Ovrg high/low is the reason for PLL Lock state?

2)What CP Ovrg high /low means?

 

 

 

 

Thanks.
