- **Caution**: 

### Q: What is the primary function of a clock synchronizer in data interface systems?
**A**: A clock synchronizer ensures precise timing alignment between different components in a data interface system, preventing data errors and maintaining signal integrity by coordinating clock signals across the system.

### Q: What materials are used in the construction of this clock synchronizer?
**A**: This clock synchronizer is constructed using silicon semiconductor for the core circuitry, copper interconnects for electrical connections, and a ceramic substrate for thermal stability and durability in electronic manufacturing environments.

### Q: How do the BOM components (Phase Detector, VCO, Loop Filter) work together in the synchronizer?
**A**: The Phase Detector compares input and output clock signals, the Voltage Controlled Oscillator (VCO) generates the output clock, and the Loop Filter smooths the control signal to eliminate jitter, creating a stable, synchronized output for precise timing in data interfaces.
