Functional Features

• Spread Spectrum Clocking (SSC): Reduces electromagnetic interference (EMI) by modulating the output clock frequency.
• Phase-Locked Loop (PLL): Generates stable and precise clock signals by locking onto an input reference signal.
• Clock Multiplication: Multiplies the input clock frequency to provide higher-frequency output clocks.
• Skew Control: Allows adjustment of the phase relationship between different output clock signals.

Advantages and Disadvantages

Advantages: - High-performance signal conditioning and timing solution - Versatile output options for different applications - Low-power consumption - Spread Spectrum Clocking reduces EMI

Disadvantages: - Limited number of outputs (4) - Requires external power supply and clock source

Working Principles

The DS2167 operates by receiving an input clock signal (CLKIN) and processing it using internal circuitry. The PLL locks onto the input clock, generating a stable reference for the output clocks. The clock multiplication feature allows the user to select the desired output frequency. The SSC feature modulates the output clocks to reduce EMI. Skew control enables fine-tuning of the phase relationship between different output clocks.
