Working Principles

The 8T49N203A-016NLGI8 utilizes advanced PLL (Phase-Locked Loop) technology to generate and attenuate clock signals. It consists of a voltage-controlled oscillator (VCO), phase detector, loop filter, and output dividers. The VCO generates the desired frequency, which is compared with a reference signal using the phase detector. The resulting error signal is filtered and used to control the VCO's frequency, ensuring synchronization with the reference signal. The output dividers divide the VCO frequency to obtain the desired output frequency.
