AD2S1210 RDC IC functionality lost only due to /reset pin!

Hello,

        I have developed a custom board for AD2S1210. This board works correctly.

 

Observation:

         1. The /reset pin of IC loads the supervisory circuit. Hence the /reset pin goes to 0V from 5V in few seconds after start.

         2. When the /reset pin is forced high manually by applying the +5V supply, the system works. ( I have put the system on complete                    functional test for 45 min after doing this and the system works correctly).

 

Request for Solution:

          1. What would have caused the failure of /reset pin only.

           

Thanks & Regards,

Shantanu.
