Working Principle

The SI5023-D-GMR is designed with a crystal oscillator and a digital phase-locked loop (PLL) circuit. The crystal oscillator generates an accurate and stable frequency, which is then fed into the PLL circuit to generate an even more precise and stable clock frequency.

The PLL circuit is controlled by a digital loop control circuit, which samples the output of the crystal oscillator and compares it with a reference frequency. From the comparison, it determines the amount of phase difference. The loop control then adjusts the output frequency of the clock in order to minimize this phase difference. This enables the oscillator to generate an extremely accurate output frequency.

In addition, the SI5023-D-GMR utilizes a wide variety of output configurations, including single-ended and differential clock outputs. Single-ended outputs provide a clock signal with a single positive voltage swing, while differential outputs provide a clock with Two complementary voltage swings. This enables the SI5023-D-GMR to be used in a wide variety of applications.
