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
