•
•
The package is not hermetically sealed.
The sides are intentionally left open to permit cleaning material to freely flow in the package, thus minimizing
the accumulation of contaminants during cleaning processes.
•
The internal part of the package must be thoroughly dry before operating.
Pad 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.

Ground (GND)
Output
Supply Voltage
(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.
