My customer decied to use AD9691 in their new product.

And they are testing the operation & performance of this device now.


During their test, they have a problem at CH B ADC

They say that in case of CH A, they confirmed a normal operation of ADC.

But at CH B, they say that CH B ADC doesn't operated normally.

Also they say that JESD204B testpattern can be confirmed at both CH A & CH B JESD204B outputs.

Unfortunately they only have one AD9691, so they can't do a replacement test.

So they request your help about their register setting values.


Please refer their register configurations and let me know your opinions.

(In ad9691 Test status.pdf, Blue box means "normal operation" and Red box means "adnormal operation".)


If you have any questions, please let me know.
