1. 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.
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 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
