Description
Connection Guidelines
VBAT
Power supply
Place 1 mF (min) decoupling capacitor close to pin
Connect negative terminal of capacitor to digital ground plane
VREG, VDDA
Internal regulator for analog
blocks
Place separate 1 mF decoupling capacitors close to each pin
Connect negative capacitor terminal to analog ground plane
Keep away from digital traces and output traces
VREG and VDDA may be used to generate microphone bias
VSSA
Analog ground return
Connect to analog ground plane
VDDD
Internal regulator for digital core
Place 1 mF decoupling capacitor close to pin
Connect negative terminal of capacitor to digital ground plane
VSSD
Digital ground return
Connect to digital ground plane
VDDO
Digital I/O power
Place 1 mF decoupling capacitor close to pin
Connect negative terminal of capacitor to digital ground plane
Connect to VBAT, unless the pad ring must use different voltage levels
MIC0, MIC2,
AI1/LOUT1,
AI3/VMIC/LOUT0
Audio inputs / Microphone bias
Keep traces as short as possible
Keep away from all digital traces and audio outputs
Avoid routing in parallel with other traces
Never connect AI3/VMIC/LOUT0 to ground
A_OUT0, A_OUT1
Audio outputs
Keep away from audio inputs
Differential traces should be of approximately the same length
Ideally, route lines parallel to each other
VSSRCVR
Output stage ground return
Connect to star ground point
Keep away from all analog audio inputs
EXT_CLK
External clock input
Minimize trace length
Keep away from analog signals
If possible, surround with digital ground
DMIC_OUT
Digital Microphone Output
Minimize trace length
Keep away from analog signals
If possible, surround with digital ground
