Pad Function
Note
When this pad is not connected the oscillator shall operate.

Output
Enable/Disable
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.

Output
There is no internal connection to this pad
The outputs must be terminated, 100 ohms between the outputs is the ideal
termination.
Output*
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.
