TLV320AIC1110: Handling of VSS pins

Tool/software:

Hi team,

Should the VSS pin be connected to analog ground?
The surrounding pins are digital pins and are not easy to handle.
A recommended layout would be helpful, but since it doesn't seem to be available from looking at other E2Es, any recommendations on how to handle the VSS pin alone?

Best Regards,
Ryu.

    Hi Yamashita-san,

    The ground pins can all share a common ground plane. The different VSS pins help identify the respective grounds for each supply so that you place the decoupling capacitors correctly. For example the decoupling of EARVDD should return quickly to EARVSS.

    Best regards,
