Clock Drivers & Buffers

Clock drivers and buffers are two electronic components commonly used in digital systems to control the timing and distribution of clock signals.

Clock drivers are electronic components that generate a clock signal and distribute it to multiple components or devices within a digital system. The clock signal is a periodic waveform that synchronizes the timing of different operations within the system. The clock driver typically amplifies and shapes the clock signal to ensure that it meets the timing requirements of the system.

Buffers, on the other hand, are electronic components that amplify and isolate signals. In digital systems, buffers are often used to distribute clock signals to multiple components without degrading the quality of the signal. Buffers can help to reduce signal distortion, noise, and jitter, which can be particularly important in high-speed digital systems.

Buffers can also be used to isolate signals and prevent interference between different components or devices. They can be particularly useful in situations where the output of one device or component could damage another device or component.

Clock drivers and buffers can be used together to distribute clock signals throughout a digital system while maintaining signal integrity. The clock driver generates the clock signal and distributes it to the buffers, which then amplify and isolate the signal before distributing it to the various components or devices within the system.
