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 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. 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
