Function
Note
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.
No connect
Ground (GND)
Output
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
There is no internal connection to this pad
