A clock generator is used to produce a clock pulse. timing signals. Microprocessors and other integrated circuits use a clock to function. A clock generator is available as a single integrated circuit and is commonly used as the clock source for various electronic and processing systems. The clock generator is used to set a time or speed to which individual units synchronize. The process of synchronization is very important in complex processes and programs that use many devices.



Working of a clock generator:

The clock generator is an electrical circuit with a resonant circuit and an amplifier. The resonator circuit is made up of a quartz piezo-electric oscillator. The amplifier circuit inverts a signal from the oscillator and some portion is led back into the oscillator so that the oscillation continues.



Types of clock generators:

micro controller type with a crystal oscillator

micro controller with resistor-capacitor pair

Programmable: Different output levels can be programmed. Used in graphics,CLOCK GENERATOR category (Timing Circuits) Articles disk drives and clock synchronizing applications.

Flexible type

direct rambus clock generator: performs clock multiplication using PLL

Multi-clock generator: can generate multiple systems clocks

Clock generator with dual 1-to-4 buffers

Dual PLL multi-clock generator
