Working Principle

A Phase Lock Loop (PLL) can be thought of as an oscillator-based control system. The purpose of a PLL is to generate an output signal with a frequency and phase that are related to a reference frequency and phase. The PLL combines the features of an oscillator with those of a feedback control system.

The PLL1700EG uses a voltage controlled oscillator (VCO) to generate its output signal. This voltage controlled oscillator has a frequency that is determined by a tuning voltage applied to it. The tuning voltage is applied to the oscillator through a loop filter.

The loop filter is used to filter the tuning voltage and generate a control voltage. This control voltage is then compared to a reference voltage. The output of this comparison (error signal) is used to adjust the tuning voltage. This forms the feedback system of the PLL.

The PLL1700EG has several controlling pins that allow the user to customize the behavior of the PLL. These include a stability control pin (FAST), a noise filter pin (NF), and a gain adjustment pin (GAIN). These pins allow the user to precisely control the loop filter, the response time of the PLL, and the bandwidth of the PLL.

The PLL1700EG also includes several other features such as a frequency doubler, a phase detector, and a lock detector. The frequency doubler allows the user to double the output frequency of the PLL. The phase detector can be used to compare the phase of two signals. The lock detector can be used to detect when the PLL is in lock and when it is out of lock.

In summary, the PLL1700EG is a highly versatile PLL chip designed for clock/timing applications such as clock generators, PLLs, and frequency synthesizers. It is capable of operating over a wide frequency range and responding quickly to input changes. It also includes several controlling pins and features to customize the behavior of the PLL according to the user\'s needs.
