PE33 PE37 Function
Pad Pad
Note
2
1 Output
When this pad is not connected the oscillator shall operate.
Enable/Disable 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.

2 No connect
There is no internal connection to this pad
3
Ground (GND)

Output
5
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 Recommend connecting appropriate power supply bypass capacitors as close as
(V_CC)
possible.
