1. What are clock buffers and drivers?

Clock buffers and drivers are electronic components used for distributing and enhancing clock signals. The clock buffer is used to replicate clock signals and distribute them to multiple outputs, while the driver enhances the signal strength to drive higher loads or longer transmission distances.
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.
