Hi,

 

I'm using AD9517-3 clock synthesiser with the internal VCO mode for clock synthesis for data converters.

 

1. The synthesiser fails to lock occasionally while attempting to reconfigure.

Is there any sequence to be followed other than that mentioned in Page 30 of datasheet.

 

2. After resetting AD9517 with soft reset and additional delay is required before configuring, in some units. Is is mentioned anywhere about the correct delay value required after reset?

 

Regards,

Vishnu
