Hello ,


I have some questions about AD9628 initialize.


ADC freeze when power up and start clocking with PDWN high.

If PDWN goes low , sometimes ADC does not work.


1) Is it correct operation ? or do you inhibit PDWN goes high ( or low ) during initializing ?

2) Do you inhibit register setting change during initializing ?

   ( Does ADC freeze ?)

3) How many clock does device need to complete initializing ?
