I am using AD9690 to sample data at 500M, and I want to use two lanes to transmit data.
However I failed to find how data are mapped to two lanes in the datasheet. This is really important , because I write the receiver myself , so I have to demap the data.
Suppose I set L=2; M=1; F=4; S=4;
Question 1 : Are the structure shown in the following picture right?
Question 2 : Does N1 transmit first or N4 transmit first ?
