Pad Function

Note

Output

Enable/Disable

The oscillator shall operate when this pad is not connected.

The output will be inhibited (high impedance state) when this pad is logic low.

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

No connect

Ground (GND)

Output

There is no internal connection to this pad. Recommend connecting to pad 1 to permit E/D input on either pad for layout.

Both outputs must be terminated and biased for proper operation. The ideal termination is 50 ohms connected to 2.0V

below supply voltage

Output*

V_CCSupply Voltage

Connect an appropriate power supply bypass capacitor as close as possible to pad 4

For Optimum Jitter Performance, Pletronics recommends:

A ground plane under the device

Do not route large transient signals (both current and voltage) under the device

Do not place near a large magnetic field such as a high frequency switching power supply

Do not place near piezoelectric buzzers or mechanical fans
