Pad Function

Note

Output

When this pad is not connected the oscillator shall operate.

Enable/Disable

When this pad is <0.30 volts, the output will be inhibited (high impedance state.)

Recommend connecting this pad to V if the oscillator is to be always on.

No connect

Ground (GND)

Output

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.

Output*

Supply Voltage

Recommend connecting appropriate power supply bypass capacitors as close as

possible.

(V )

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.
