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.
