Working Principle

The working principle of 8T49N285-998NLGI is based on a phase locked loop (PLL) architecture, which allows it to generate and control precision frequency sources with very low jitter. The PLL operates by locking the phase of an incoming reference clock signal, and then using an adjustable voltage-controlled oscillator (VCO) and phase/frequency detector (PFD) to lock the phase of the output signal to the reference clock signal.

The PLL also allows for the control of the output frequency by using a variety of multiplier and divider circuits and using an adjustable voltage-controlled oscillator (VCO) to control the frequency of the output signal. This allows 8T49N285-998NLGI to generate a wide range of frequencies with low jitter and high accuracy.

The 8T49N285-998NLGI also features a frequency synthesizer, allowing users to generate low jitter clock sources from multiple reference clocks, and to control the frequency spectrum through frequency/phase modulation. All of these features combined make 8T49N285-998NLGI one of the best clock and timing generator and frequency synthesizer solutions available on the market today.
