It is also frequently used in the communications and consumer electronics markets, providing precise and reliable clock signals for systems such as servers, fiber-optic telecommunications, cellular phones, GPS systems, and satellite TV receivers.

Working Principle:

The 8T49N008A-048NLGI is a programmable clock generator with a built-in phase locked loop (PLL) circuit. This PLL circuit is designed to generate a precise, high-frequency clock signal in response to input signals from an external source such as an oscillator or a digital logic circuit. The PLL circuit utilizes a voltage controlled oscillator (VCO) to produce the desired output frequency. The VCO is regulated by two feedback loops, a frequency loop and an amplitude loop, which provide precise frequency and amplitude control of the clock signal, allowing it to be accurately tuned to the desired frequency.

The 8T49N008A-048NLGI also features a dual-type loop filter, which is a combination of an active low-pass filter and a passive low-pass filter. This dual-type loop filter allows for precise adjustment of the VCO\'s frequency and amplitude, guaranteeing a high level of accuracy in the output frequency. Finally, the 8T49N008A-048NLGI is also able to generate a two-phase output clock, allowing it to be used in applications where two separate clock signals are required.

Conclusion:

The 8T49N008A-048NLGI is an extremely accurate and reliable clock generator capable of producing a precise high-frequency clock signal from an external source. It features a dual-type loop filter and a PLL circuit to ensure that its output frequency is consistent and accurate, making it suitable for many timing and clock applications. Its two-phase output clock is particularly useful for applications that require two separate clock signals. As such, the 8T49N008A-048NLGI is an excellent choice for any system that needs an extremely precise clock signal.
