Thanks. One more question is regarding hardware signal integrity problem about my custom board. If the hdl build works for eval board and not for my custom board I am guessing maybe there is signal integrity issue here as well for me not be able to see dds tone at all.

 

1. Any vdd on ad9371 need to be more attention?

 

2. Tx data trace matching problem will cause data not being aligned properly and maybe sync never go static high?

 

3. I am seeing high dc voltage offset at tx sync line with fast pulsing on my board, but eval board i see a short period of pulses high and then went to static high. Is this ok?
