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. 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.
-
3. What output configurations does the clock buffer support?
Clock buffers typically support multiple output configurations, including single ended output, differential output, programmable delay, or selectable output frequency, to accommodate different system requirements.
-
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
