•

The package is not hermetically sealed.

•

The sides are intentionally left open to permit cleaning material to freely flow in the package, thus

minimizing the accumulation of contaminants during cleaning processes.

•

The internal part of the package must be thoroughly dry before operating.

Function

Note

1

Output

Enable/Disable

When this pad is not connected the oscillator shall operate.

When this pad is <0.30 volts, the output will be at a steady, non switching state.

Recommend connecting this pad to V

1

2

No connect

There is no internal connection to this pad

3

Ground (GND)

4

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

Supply Voltage

(V

Recommend connecting appropriate power supply bypass capacitors as close as

possible.
