Output
Enable/Disable
When this pad is not connected the oscillator shall operate.
When this pad is logic low the output will be inhibited (high impedance state.)
Recommend connecting this pad to V
CC
if the oscillator is to be always on.

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 while avoiding connection to the two dot pads on the bottom. Use
the PCB solder mask to isolate the two dot pads
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.
