Hello,

 

After having be able to use AD9625 in full bandwidth mode, I'm now trying to make it works in DDC mode. But it doesn't seem to work.

I have several questions. Here they are :

 

1) When in DDC mode (High BW or Low BW), are others JESD lanes powered on by AD9625 ? I mean, is it normal to get lanes synchronyzed (receiving 0xBC K-Charcater) and after to get ILA and datas ?

 

2) In Low BW mode, is it right to say that I should get data only on lane #0 in thi sort : I(MSB) / I(LSB) / Q(MSB) / Q(LSB)

 

3) To succesfully get data in Low BW Mode, what is the simplest way to configure AD9625 through SPI ? I mean list of registers and value to write.

 

 

Thanks for your support.
