How a Quartz Crystal Oscillator Can Increase Frequency Stability

When you choose a new oscillator, you want to make sure that you’re getting the highest quality possible. Frequency stability is one of the most important factors to consider — and when it comes to frequency stability, a quartz crystal oscillator will always be your best option.

There are lots of benefits to using a quartz oscillator, whether you’re building a clock or working with radio frequencies. The biggest advantage is its high-frequency stability, or how long it’s able to provide a constant frequency.

So how can a quartz oscillator increase your frequency stability?

Read on to find out.

1. Low-Frequency Drift

An electrical engineer’s worst nightmare is frequency drift. You need your oscillator to stay at the same frequency no matter what. When materials age, though, their frequencies can change slightly.

Quartz crystal oscillators age very slowly already, but they are kept further in check with temperature control. Other oscillators need a lot more help, and improving them would be hard.

As long as you store quartz crystal properly, you can rest assured that it will keep working the way you want.

2. Simple Customization

Not all quartz crystals have the same frequency. The frequency changes depending on the size, shape, and thickness of the crystal. It all depends on how you cut it.

Regardless of the frequency you’re looking for, a quartz crystal will stay consistent. You’ll get a huge range of frequencies to choose from, so it can suit any need you have.

3. High Q

Anything that has energy can lose energy.

When you’re creating something that relies on a consistent frequency, this creates a pretty obvious problem. The frequency won’t be the same if the oscillator is slowly losing energy.

Quartz oscillators have a very high Q factor, which means that it takes them much longer to lose energy. You can use a quartz crystal oscillator with confidence knowing that it won’t use up a ton of energy maintaining the same frequency.

4. Low Phase Noise

All oscillators, no matter which one you use, are going to have some phase noise. Phase noise is another way to discuss the amount of jitter on a frequency.

The idea is to have a smooth frequency wave with tiny variations. Getting a perfect wave isn’t likely, though, so instead you should look for something with low phase noise to make sure you get the best results.

The high Q factor of a quartz oscillator helps to lower the phase noise and keep everything running perfectly. This is especially important for people using a quartz crystal oscillator for their radio frequencies.
