Function
Note
1
Output
Enable/Disable
When this pad is not connected the oscillator shall operate.
When this pad is <0.80 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
The pad can be connected to Vcc, Ground or left open. This pad is internally
connected.
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.
The outputs become a High Z when disabled and the voltage level is determined
by the termination circuitry.

Recommend connecting appropriate power supply bypass capacitors as close as
possible.
