Working Principles

The 8T49N524-007NLGI utilizes a crystal oscillator as its input source. The crystal oscillator generates a stable reference frequency, which is then multiplied and divided to generate the desired output frequencies. The device also incorporates a phase-locked loop (PLL) to synchronize the output clocks with the input reference.

To reduce jitter, the 8T49N524-007NLGI employs advanced techniques such as phase interpolation, phase alignment, and voltage-controlled oscillators. These techniques help attenuate unwanted noise and improve the overall quality of the generated clocks.
