Working Principles

The DS2167QN operates by receiving an input clock signal (CLKIN) and conditioning it to generate multiple output clock signals (CLKOUT0-3). The device uses internal PLLs (Phase-Locked Loops) to multiply or divide the input frequency based on the desired output frequencies. It also incorporates phase alignment circuitry to synchronize the phase of the output clocks. The conditioned clock signals are then made available at the respective output pins.
