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 difference between an oscillator and a clock?
The main difference between an oscillator and a clock is that they have different functions and uses. An oscillator is an electronic component that can convert DC power into AC power with a certain frequency, and autonomously generate periodic signals, and is often used in clock circuits, communications and other fields. The clock is used to generate and maintain stable and accurate time signals to ensure the synchronization and coordination of electronic equipment.
An oscillator is an electronic circuit or device whose function is to convert direct current (DC) energy into alternating current (AC) energy with a certain frequency, amplitude and waveform. It can spontaneously generate and maintain a stable oscillation state without external periodic signal drive, and output continuous and repetitive AC signals. Oscillators are widely used in many fields such as electronic engineering, communications, measurement, computer systems, clock synchronization, and control equipment. -
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.
