Component Specifications

Definition
A clock distribution tree is a structured network within digital systems that delivers synchronized clock signals from a single source to multiple destination points (such as flip-flops, latches, or other clocked elements) across an integrated circuit or printed circuit board. It is designed to minimize clock skew, jitter, and power consumption while ensuring reliable timing for synchronous operations.
Working Principle
The clock distribution tree operates by receiving a master clock signal from an oscillator or PLL (Phase-Locked Loop) and distributing it through a branching network of buffers and interconnects. It uses balanced routing, impedance matching, and buffer insertion to maintain signal integrity, equalize propagation delays, and reduce timing variations across all endpoints.
Materials
Typically fabricated using silicon-based semiconductor materials (e.g., silicon wafers with copper or aluminum interconnects), with dielectric insulators (e.g., silicon dioxide) and may include materials like low-k dielectrics for high-speed applications.
Technical Parameters
  • Skew < 10 ps
  • Jitter < 1 ps RMS
  • Number of Outputs Up to thousands
  • Operating Voltage 0.8V to 3.3V
  • Power Consumption Varies with design, typically 5-20 mW
  • Clock Frequency Range 1 MHz to 10 GHz
Standards
ISO 9001, IEC 60749, JEDEC JESD65B
