Introduction to Frequency Control
Frequency control is the process of maintaining the stability of clocking and timing in digital devices. All digital circuits today require clocks to ensure that processes happen at very specific intervals. In the 1970s, the digital watch was introduced. The design used kHz watch crystals to keep the timing, which is a process we still use today. Real-Time Clocks (RTCs) are used for timing in most processors and are used in registers as counters.
Oscillators provide RF signals and TCXOs are used in two-way communication devices to provide clear communication. Learn more about the specifics of frequency control in the full version of this tech guide.
