Pad Function
Note
When this pad is not connected the oscillator shall operate.

Output
Enable/Disable
When this pad is < ‘V disable’, the output will be inhibited (high impedance state.)
Recommend connecting this pad to V if the oscillator is to be always on.

Layout and application information
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable input on
either pad
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.
