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. 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. 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
