If I place these two ICs in the same layer (TOP or Bottom), ananloig signals (VOP, VON) cannot be conencted direcly. (one or two vias should be used.)
Ss, I am a little concern about performance degrade due to via.
I saw ADS1274 datasheet (Figure 89), and I found inverted output is connected to AINP, and non-inverted output is connected to AINN.
In this case, is there just phase reverse effect?
What is the recommeded method for differential pairs trace?
- normal connections with one or two vias
- or reverse connections with no vias
Let me know your opinions.
Thank you for your advice in advance
