XCO3 - A low cost Crystal Oscillator Module

For any standard 7 x 5 mm Oscillator

The assembled prototype

✈ Motivation • Design Criteria

On one hand, we wanted a calibrated Source for the EMC-Precompliance Setup. On the other hand, a Source to study the Harmonics of a Standard Crystal Oscillator was desirable.

This is a board to house any 7 x 5 mm Crystal Oscillator. A Voltage Regulator supplies it with a stable 3.3 V / 5 V, max. 100 mA. We used the SO-8 78LXX type Voltage Regulator for that.

In order to use 50 Ω Measurement Gear, a massive Output Divider (30 dB) does this matching thing, without loading the Oscillator too much.

✈ Performance • 4.096 MHz

The CMOS oscillator creates beautiful Harmonics (FSP is 50Ω)

Whilst in the time domain it is close to a squarewave (SCOPE is Hi-Z)
