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.

Function
Note
2
1
Output
Enable/Disable
When this pad is not connected the oscillator shall operate.
When this pad is <0.30 volts, the output will be at a steady, non switching state.
Recommend connecting this pad to V
CC if the oscillator is to be always on.
1
2
No connect
There is no internal connection to this pad
3
Ground (GND)
4
Output
The outputs must be terminated, 100 ohms between the outputs is the ideal
termination.
When the device is disabled, the Output will be an active logic low and the
Output* will be an active logic high.
The outputs can not be “wire-ORed” with other oscillators or signal generators

6
Supply Voltage
(V
CC)
Recommend connecting appropriate power supply bypass capacitors as close as
possible.
