Working Principle

The PI6C2409-1LIE contains a total of four blocks: the phase-locked loop (PLL), the phase detector (PD), the loop filter (LF), and the internal oscillator (OSC). The phase-locked loop is responsible for phase locking, phase tracking and synchronization, whereas the phase detector decides on the degree of phase error between the incoming signal and the output signal. The loop filter integrates the phase detector signals, and provides the feedback signal to the PLL to maintain phase locking. The internal oscillator generates the signal that will be output to the system.

The phase-locked loop is the major block responsible for the control of frequency synthesis. It adjusts the frequency to maintain phase locking and synchronization between the input signal and the output signal. It can detect the phase errors between input signal and output signal and generate a voltage to the loop filter accordingly. The loop filter then integrates the signal and produces a control voltage to drive the internal oscillator to maintain phase locking between input signal and output signal.

The phase detector ensures that the frequency of the input signal is accurately maintained. It does this by checking the frequency and phase difference between the two signals. If an error is detected, the phase detector generates a voltage to the loop filter accordingly to adjust the frequency.

The loop filter is responsible for providing feedback to the PLL to keep phase-locking and adjusts the frequency based on the phase detector’s request. It integrates the signals from the phase detector and generates a feedback voltage. This feedback voltage is then applied to the internal oscillator to maintain an accurate frequency output.

The internal oscillator is responsible for generating the output signal to the system. It is also designed to maintain a precise frequency as requested by the loop filter. The resulting frequency output can be adjusted as desired using the PLL, or by using external digital Pulse Width Modulation (PWM) signals.

The PI6C2409-1LIE is a highly integrated and multi-functional clock-synthesizer IC, which can provide the customized timing designs to a wide range of applications. It has the flexibility of adjusting the frequency with great accuracy and can offer high-quality clock generation and frequency synthesis with ease.
