Hi,

When using CSX, the Cint caps have their return path to analog ground (VSSA). If I am using CSX and CSD widgets simultaneously, can I join the return paths for Cmod and Cints like this :

And a single trace connects this nod to analog ground (VSSA)

OR

is it better to split signals and have a trace to VSSA for Cmod separate from a second trace to VSSA for Cints:

Thank you!

Hi @jcsb1994,

The routing done in the first picture is better.

It is always recommended to have the shortest GND trace possible and connect it to the nearest VSSA.
