Clock, Timing & Frequency ICs

Clock, timing & frequency ICs are electronic devices that provide timing frequency to circuits. A clock IC is an electronic device that is used for the generation, manipulation, distribution, conditioning, or controlling of a timing signal in electronic systems. A timing IC is used to control sequences of events in electronic systems. Frequency ICs are circuits that have been designed to keep a circuit tuned to the frequency of an incoming radio signal.

What types of clock, timing & frequency ICs are there?

Clock, timing & frequency ICs have a range of different functions such as;

Clock Drivers, Distribution
Clock Synthesizers
Delay Lines & Timing Elements
Clock Buffers
Bus Repeaters
Function Generator IC
Phase Detectors
Real-Time Clocks
Timer Circuits
Watchdog Timers

Typical applications

Clock, timing & frequency ICs are widely used in an array of applications such as;

Low jitter, low phase noise clock distribution
Wireless transceivers
ATE (Automatic test equipment)
Sensory applications
Frequency translation and low-frequency PLLs
