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. 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.
3. How to evaluate the performance of clock drivers?

When evaluating clock drivers, several key parameters need to be considered:

Driving capability (load capacity)

Output signal integrity

Phase noise and jitter

Power noise suppression

Power supply voltage range and power consumption
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.
