The Power of Crystal Units

The “heart” of the machine that keeps its rhythm.

Crystal units have the power to send signals with good rhythm. If you think of a machine like a person’s body, the crystal unit is the heart.
Just like when the heart pumps blood to your body, the crystal unit keeps rhythm for the signals it sends.

An illustration showing how crystal units work as parts in the human body. The heart is the crystal unit, and the blood is the signals.

The Secret of the Power of Crystal Units

Crystals vibrate when they get electricity.

Crystal units have a crystal inside. It vibrates with an exact rhythm when it gets electricity. This rhythm controls when signals are sent.
Crystals aren’t just pretty gems, they have neat powers too!

Friends of Crystal Units

Ceramic Resonators

Crystal units are a type of “oscillator”. Other types can be made from piezoelectric ceramics.

Trivia

What are the units?

We measure the signals crystal units send out in units of “Hz” (hertz). This number shows how many times the crystal vibrates per second.
For smartphone crystal units, it’s about 10 MHz. That’s 10 million times each second!

Crystal units are also used in watches!

Crystal units are so good at their job that they can even tell time as a clock or watch.

Think it out!
