FAQ about Clock/Timing - Programmable Timers and Oscillators
-
1. What is a programmable timer?
A programmable timer is a device that can be preset by manually setting programming instructions and accumulate timing according to clock pulses. It allows users to set specific timing tasks as needed, and automatically perform corresponding operations after reaching the preset time. Programmable timers are widely used in various occasions, from computer rooms, schools and mechanical institutions to kitchen appliances in homes.
Programmable timers are based on the accumulation of clock pulses, and clock pulses have different specifications such as 1ms, 10ms, and 100ms. (The working process of the timer is actually counting clock pulses) Due to work needs, in addition to occupying its own numbered memory bit, the timer also occupies a set value register (word) and a current value register (word). The set value register (word) stores the timing time setting value assigned during programming. -
2. What is the most commonly used oscillator?
The most commonly used oscillator is the crystal oscillator. A crystal oscillator is an oscillator based on quartz crystals. It has the characteristics of accurate frequency, good stability, low noise, and long life. It is widely used in high-precision fields such as clocks, timing, and measurement.
Crystal oscillators use the mechanical resonance of quartz crystals to generate electrical signals with very precise frequencies. Such oscillators have high stability, quality factor, small size, and low cost, making them superior to other resonators such as LC circuits, ceramic resonators, and forks.
In addition to crystal oscillators, other common oscillator types include LC oscillators and [oscillator tube oscillators. LC oscillators are oscillators based on inductors and capacitors, which are suitable for lower frequency ranges, such as radio frequency amplifiers, radio transceivers, digital televisions, etc. Oscillator tube oscillators are often used in amplifiers, generators, mixers, and other fields in the microwave frequency band. -
3. What are the three types of oscillators?
There are three main types of oscillators: RC oscillators, LC oscillators, and crystal oscillators.
RC oscillators are oscillators that use an RC network as a frequency-selective phase-shifting network. They are usually used to generate sinusoidal signals and are suitable for the audio range. This type of oscillator has the characteristics of simple structure and low cost, and is often used in various electronic devices.
LC oscillators are positive feedback oscillators that use an LC oscillation loop as a phase-shifting frequency-selective network. They are suitable for lower frequency ranges, such as RF amplifiers, radio transceivers, and digital televisions. LC oscillators can be classified into three types according to the different feedback methods: transformer feedback, inductor feedback, and capacitor feedback.
