What is the lock in range of a phase locked loop?

The range of frequencies over which PLL will track the input frequency signal and remains locked is referred as PLL Lock range. The lock range is usually band of frequencies above and below the PLL free running frequency as described earlier.

What is the lock range and capture range?

Lock range (and hold range) shows how far the PLL frequency can track an input signal. Capture range (and pull-in range) shows how far from the free running frequency the VCO will move to lock onto an input signal.

What is the input at the phase detector?

The inputs of PD are high-frequency signals and the output contains a low-frequency error correction signal, corresponding to a phase difference of input signals. For the suppression of high-frequency component of the output of PD (if such component exists) a low-pass filter is applied.

At which state the phase locked loop tracks any change input frequency?

3. At which state the phase-locked loop tracks any change in input frequency? Explanation: In the phase-locked, the output frequency is exactly same as the input signal frequency. So the circuit tracks any change in the input frequency through its repetitive action.

What is operating frequency range of IC 565?

Operating frequency range: 0.001Hz to 500 Khz. Operating voltage range: ±6 to ±12v.

What is the function of the phase detector in a phase locked loop?

A phase detector compares two input signals and produces an error signal which is proportional to their phase difference. The error signal is then low-pass filtered and used to drive a VCO which creates an output phase.

What is the phase difference between the phase detector inputs in a locked PLL?

The main purpose of a PLL circuit is to synchronize an output oscillator signal with a reference signal. When the phase difference between the two signals is zero, the system is “locked.” A PLL is a closed-loop system with a control mechanism to reduce any phase error that may occur.
