Hi all

 

I have some inquiries about AD9250 from my customer.
My customer says,
When he resets AD9250, it occurs frequently that AD9250 does not start up correctly.
Then his questions are followings.

 

Q1. Please share the recommended width (=duration?) of the reset pulse.
        ??msec, ??usec, ??nsec

Q2. His understanding is that 500usec is required after reset until SPI setting.
       Please share the recommended value after reset until SPI setting.
       ??msec, ??usec

 

We hope quick reply.

 

Best Regards.
