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. 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 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 -
4. 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.
