Clock Buffer/Driver

Product Specifications

Technical details and manufacturing context for Clock Buffer/Driver

Definition

A clock buffer/driver is a critical component within a clock generator system that receives a reference clock signal, amplifies it to drive multiple loads, and distributes it to various subsystems while maintaining signal integrity, minimizing jitter, and ensuring proper timing synchronization across the entire electronic system. This component is used in computer, electronic, and optical product manufacturing, where precise timing is essential for reliable operation. The clock buffer/driver typically operates with a supply voltage of 1.8–3.3 V for core logic, supports output frequencies from 1 to 200 MHz, and provides output drive strength of ±24 mA per output for LVCMOS. It ensures output skew of ≤50 ps between any two outputs and additive phase jitter of ≤0.5 ps RMS (12 kHz to 20 MHz integration range). The input logic level is compatible with LVCMOS/LVTTL. The device is designed for industrial-grade operation over a temperature range of -40 to 85 °C, with a supply current of ≤50 mA at 200 MHz with no load. It is available in a QFN-16 package (4x4 mm, 0.5 mm pitch) and offers ESD protection of ±2 kV HBM per JEDEC JS-001. The component is fabricated using silicon, with copper and gold used in its construction. As a directory listing, these values are reference ranges and must be verified with the manufacturer for the specific model and application. Always consult the datasheet and confirm compliance with relevant standards before procurement or integration.

Working Principle

The clock buffer/driver operates by receiving a low-power clock input signal, amplifying it using internal transistor circuits to increase drive strength, and then distributing the amplified signal through multiple output channels. It typically includes features like impedance matching, signal conditioning, and fan-out capability to drive multiple clock inputs of other ICs while maintaining precise timing characteristics. The device ensures that the output signals maintain low skew and jitter, which are critical for synchronous operation. The amplification stage is designed to handle the specified supply voltage and output frequency range, while the output stage provides the required drive strength. The component also includes protection features such as ESD protection to safeguard against electrostatic discharge during handling and operation.
