Layout and application information
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept both Enable/Disable
input pad versions to be used (See PE37T for E/D on pad 1)
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.
