1. 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.
2. How to choose a suitable clock buffer?

When choosing a clock buffer, the following factors need to be considered:

frequency range

Number of output channels

Signal type (differential signal or single ended signal)

Phase noise and jitter performance

Power supply voltage and power consumption
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
