Function

Note

1

Output

Enable/Disable

When this pad is not connected the oscillator shall operate. This is not a

recommended condition!!!!!!

When this pad is <0.80 volts, the output will be inhibited (High impedance state)

Recommend connecting this pad to V

1

2

No function

Recommend connecting this pad to ground. The is internal connection.

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.
