Hi,

My customer will use AD9528 in buffer mode with PLL1 & PLL2 PD on.

  1. What is the delay time from VCXO_IN to OUTx In buffer mode ?

      What is the delay time from SYSREF_IN to OUTx In buffer mode ?

   2. If the VCXO_IN signal is output through the output of the channel divider in buffer mode, what is the delay time ?

       In this case, what is the resolution step of coarse delay ? Is it VCXO_IN /2 ?

   3. Which of the following datasheet contents is the correct insertion delay for the analog fine delay ?

 

Thanks a lot.
