Pad

Function

Note

When this pad is not connected the oscillator shall operate.

Output

Enable/Disable

When this pad is < ‘V disable’, the output will be inhibited (high impedance state.)

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

The outputs must be terminated, 100 ohms between the outputs is the ideal

termination.

Output*

Supply Voltage

(V_CC)

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.
