Technical details and manufacturing context for Clock Synchronizer

Definition
A clock synchronizer is a critical component within a Data Interface Controller that maintains precise timing coordination between various subsystems, ensuring data transmission occurs at synchronized intervals to prevent errors, data loss, or corruption during communication between devices or modules.
Working Principle
The clock synchronizer generates and distributes a master clock signal to all components in the data interface system. It uses phase-locked loops (PLLs) or delay-locked loops (DLLs) to align local clock signals with the master reference, compensating for propagation delays and ensuring all data transfers occur at precisely coordinated timing intervals.
Common Materials
Silicon semiconductor, Copper interconnects, Ceramic substrate
Technical Parameters
  • Clock jitter specification indicating timing precision (ps) Customizable

Frequently Asked Questions

What is the primary function of a clock synchronizer in data interface systems?

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.

What materials are used in the construction of this clock synchronizer?

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.
