Component Specifications

Definition
A specialized electronic component within FPGA (Field-Programmable Gate Array) or ASIC (Application-Specific Integrated Circuit) control logic that generates, distributes, and manages clock signals to ensure synchronized operation of digital circuits. It includes phase-locked loops (PLLs), clock dividers, and delay-locked loops (DLLs) to maintain timing integrity across industrial automation systems.
Working Principle
Operates by generating a stable reference clock signal using crystal oscillators or internal oscillators, then uses PLLs to multiply, divide, or phase-shift this signal to create multiple synchronized clock domains. It ensures minimal clock skew and jitter through precise routing and buffering, enabling deterministic timing for sequential logic circuits in industrial controllers.
Materials
Semiconductor materials (silicon, gallium arsenide), copper interconnects, ceramic or plastic packaging with gold-plated pins for reliability in industrial environments.
Technical Parameters
  • Jitter < 50 ps RMS
  • Phase Noise < -100 dBc/Hz at 10 kHz offset
  • Output Types LVCMOS, LVDS, HSTL
  • Supply Voltage 1.2V to 3.3V
  • Frequency Range 1 MHz to 500 MHz
  • Operating Temperature -40°C to 85°C
Standards
ISO 26262, IEC 61508, JEDEC JESD65B
