SMD and Quartz Crystal Oscillators
We receive many questions as to what the crystals in devices actually do. Essentially, the crystal is a thin slice of quartz that is placed between two electrodes. Crystals are used in a number of applications requiring precise vibration frequencies. An electric signal with a very precise frequency is generated by the crystal oscillator. The technology is frequently used in cellphones, computers, wristwatches, clocks, and radio transmitters and receivers.
There are three principal uses of crystal frequencies:
1) Keeping track of time.
2) Providing a stable clock signal.
3) Frequency stabilization for radio receivers and transmitters.
Quartz crystal frequencies have a range that extends from a few tens of kilohertz, to hundreds of megahertz. This all depends on the thickness of the crystal, allowing for a vast number of applications and uses. Quartz crystal oscillators are used in devices ranging from common consumer electronics to specific equipment used to measure and monitor frequencies.
SMD (surface mount) crystals are used where the small size of the crystal is of utmost importance, such as crystals used in communications, microprocessors, and watches.
