3.5 PCB Layout Considerations
AS72651/AS72652/AS72653 has same 20-pin LGA package sharing same PCB footprint.

The PCB layout for AS72651/AS72652/AS72653 devices is simple. The first recommendation is to
place the decoupling capacitors closed to VDD pins of AS72651/AS72652/AS72653 devices. The
second recommendation is to avoid to put any via underneath the device. Please refer to the Figure
below.

For the system level layout consideration, the generic PCB layout rules for digital designs should
apply. In general, the wiring must be chosen so that crosstalk and interference to/from the bus lines
