1. 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.
2. 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.
3. Does the clock driver support differential signals?

Yes, many clock drivers support differential signaling, such as LVDS, CML, and HCSL, which can provide higher anti-interference capabilities, especially in high-speed signal transmission applications.
4. How do clock buffers and drivers help with timing design?

Clock buffers and drivers ensure that multiple components in the system can work synchronously at precise time points by providing stable, low jitter clock signals, thereby optimizing timing design, especially in high-performance computing and communication systems.
