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 VCC if the oscillator is to be always on.

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
