| Clock Oscillators |
 |
| Quartz crystal oscillators are comprised of a crystal unit and an inverting amplifier; and emit a stable frequency when subjected to a specific voltage. Quartz crystal oscillators are a simple means of providing the clock generators used for information processing in office automation and other electronic equipment. |
| Temperature Compensated Crystal Oscillators (TCXOs) |
 |
| A temperature compensated crystal oscillator (TCXO) compensates the frequency-temperature characteristics of the crystal unit using a temperature compensation circuit to provide a highly stable output frequency. They are mainly used as reference signal sources in the radio frequency circuits of cellular phones. |
