The package is not hermetically sealed (the crystal unit inside is 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
Enable/Disable
When this pad is not connected the oscillator shall operate.
When this pad is <0.30 volts, the output will be inhibited (high impedance state.)
Recommend connecting this pad to V
CC if the oscillator is to be always on.
2
No connect
There is no internal connection to this pad
3
Ground (GND)
4
Output
Both outputs must be terminated and biased for proper operation. The ideal
termination is 50 ohms connected to 2.0V below the Supply Voltage.
5
Output*
6
Supply Voltage
(V
CC)
Recommend connecting appropriate power supply bypass capacitors as close as
possible.
