DIR9001 preamble detection

Other Parts Discussed in Thread: DIR9001

 

Hello

My client is using  DIR9001 for AES/EBU decoding.

Here are questions

---------

Q1  latency of Error for preamble  

      If Preamble can not be detected, Error(#27pin) goes high after 3/fs of error event ?

      From  the DIR9001  Data sheet  Fig10 Fig14, it seems so,,,. But  Is it correct?

Q2   Do you have any  app notes for correct  preamble detection  in case PLL mode (CKSEL=GND)?

     We know the description about loop filter design in  DIR9001 data sheet page 15 ,....

I hope your advise within 4days.

Thank you and with my best regards
