Pad 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 inhibited (high impedance state.)

Recommend connecting this pad to VCC if the oscillator is to be always on.

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.

5 Output*

6 Supply Voltage

(VCC)

Recommend connecting appropriate power supply bypass capacitors as close as

possible.

Layout and application information

Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable on both

input pads

For Optimum Jitter Performance, Pletronics recommends:

• a ground plane under the device

• no large transient signals (both current and voltage) should be routed under the device

• do not layout near a large magnetic field such as a high frequency switching power supply

• do not place near piezoelectric buzzers or mechanical fans.
