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. 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. 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.
