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.
