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 are the main applications of clock buffers?

Clock buffers are widely used in systems that require the distribution of clock signals to multiple devices, such as computer motherboards, servers, communication equipment, data centers, and industrial control systems, to ensure synchronized operation of all devices.
3. 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.
4. What output configurations does the clock buffer support?

Clock buffers typically support multiple output configurations, including single ended output, differential output, programmable delay, or selectable output frequency, to accommodate different system requirements.
