If this function is not specified, recommend connecting this pad to ground.
Recommend connecting appropriate power supply bypass capacitors as close
as possible.
Layout and application information
For Optimum Jitter Performance, Pletronics recommends:
•
a ground plane under the device
•
no large transient signals (both current and voltage) should be routed under the device
•
do not layout near a large magnetic field such as a high frequency switching power supply
•
do not place near piezoelectric buzzers or mechanical fans.
