Layout and application information
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept both Enable/Disable
input pad versions to be used (See PE76D for E/D on pad 1)
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 crystal unit inside is 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.

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.)

Both outputs must be terminated and biased for proper operation. The ideal
termination is 50 ohms connected to 2.0V below the Supply Voltage.
Recommend connecting appropriate power supply bypass capacitors as close as
possible.
