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.

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.

PE33Pad PE37Pad Function Note

2

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 CC if the oscillator is to be always on.1

2

No connect There is no internal connection to this pad

3Ground (GND)4Output 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 5Output*

6

Supply Voltage (V CC )Recommend connecting appropriate power supply bypass capacitors as close as possible.
