Working Principle

The 5V49EE501NLGI8 is primarily a Hot Swap Clock Generator, also known as a Clock Multiplier. It combines a crystal oscillator and a configuration of special logic gates to generate a stable waveform with a frequency that is multiplied to a higher frequency. This higher frequency output waveform is then used as a clock reference or master clock signal in many electronics systems. In addition, the 5V49EE501NLGI8 also supports Clock Synergy, PLL and Programmable Frequency Synthesis.

Clock Synergy is used to combine multiple clocks and adjust them to match a desired frequency. This technology is used in many communications applications to synchronize different devices to each other, making the system more reliable. Clock synergy can also be used to generate multiple frequency signals from a single reference signal or to tune a signal to a higher or lower frequency.

PLL stands for Phase-Locked Loop and is used to synchronize a signal to a reference clock signal. A PLL circuit is able to determine the phase angle between the two signals and averages out the differences. This allows the signal to be synchronized to the reference clock signal and eliminates jitter and drift. The 5V49EE501NLGI8 supports up to six input and one output signal.

Programmable Frequency Synthesis is used to generate signals at any frequency within the device’s operating range. This allows a wide range of frequencies to be generated from a single reference signal. It is used in many applications such as digital broadcasting, cellular systems and Wi-Fi network communications.

The 5V49EE501NLGI8 also includes a clock fail function that keeps the device running in the event that the input reference clock signal fails or is disabled. It also provides an open-collector LOW TTL output to indicate clock failure.

The 5V49EE501NLGI8 is a cost-effective and reliable solution for clock generation, multiplying and synthesizing in a wide range of applications. It provides stable, predictable signals that can be used as a reference clock signal, eliminating jitter and drift.
