Pad Function

Note

1

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 VCC if the oscillator is to be always on.

2

Ground (GND)

3

Output

CMOS

4

VCC Supply Voltage

Connect an appropriate power supply bypass capacitor as close as possible

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

1 Typical dimensions

Contacts (pads): Gold 11.8 to 39.4 µinches (0.3 to 1.0 µm) over Nickel 50 to 350 µinches (1.27 to 8.89 µm)
