Pad Function
1 Output
Enable/Disable
2 No connect
3 Ground (GND)
4 Output
5 Output*
6 Supply Voltage
(V_CC)
Note
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 V_CC if the oscillator is to be always on.
There is no internal connection to this pad
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.
Layout and application information
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable input on
either pad
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.
