Note
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.
The pad can be connected to Vcc, Ground or left open. This pad is internally
connected.
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.
