Function
Note
1
Output
Enable/Disable
When this pin is not connected the oscillator shall operate.
When this pin is logic low the output will be inhibited (high impedance state.)
Recommend connecting this pin to V
CC if the oscillator is to be always on.

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