1. What are clock buffers and drivers?

Clock buffers and drivers are electronic components used for distributing and enhancing clock signals. The clock buffer is used to replicate clock signals and distribute them to multiple outputs, while the driver enhances the signal strength to drive higher loads or longer transmission distances.
2. What is the difference between a clock buffer and a clock driver?

The main function of a clock buffer is to distribute clock signals, while a clock driver is used to enhance signal strength to drive higher loads. Buffer is usually used for branching and synchronizing multiple clock signals, while driver is used to increase signal transmission distance and load capacity.
3. What is the function of a clock driver?

The function of a clock driver is to enhance the driving capability of the clock signal, ensuring that the signal can be transmitted further or drive more loads without causing signal attenuation or distortion. It is particularly important in high-frequency and high load applications.
4. How can clock buffers reduce jitter?

High quality clock buffers are typically designed with low jitter characteristics to ensure phase consistency of output signals and reduce phase noise during transmission. This is crucial for high-precision clock allocation, such as in communication and data transmission applications.
