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.
