Can I use GND instead of CGND or AGND

@MarkT

Make sure the analog supply is separated from the digital with a suitable ferrite bead(s) to keep high frequency noise from it

Hmm, okay I got it. I am using like this in my design. MH1608-121 has 100 ohm DCR and 120 ohm Impedance.

My 3.3V is coming from here

MarkT, you helped me a lot thank you. Should I use that CGND thing or can I just connect GND.
