Function  
Note  
1
Output  
When this pad is not connected the oscillator shall operate.  
Enable/Disable  
When this pad is logic low the output will be inhibited (high impedance state.)  
Recommend connecting this pad to VCC if the oscillator is to be always on.

(VCC)  
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.
