Synthesizer out-of-lock condition
WebThe lock range is usually band of frequencies above and below the PLL free running frequency as described earlier. Fig.1 PLL Lock Range If the frequency of the input signal is outside the PLL lock range than PLL will not be able to lock. Under this condition, VCO frequency jumps to its fundamental free running frequency. PLL Capture range WebMar 9, 2024 · The term “phase-locked loop” appears in a variety of contexts: microcontrollers, RF demodulators, oscillator modules, serial communications. The first thing to understand is that “PLL” does not refer to a single component. A PLL is a system —it consists of multiple components that are carefully designed and interconnected in a ...

WebThe phase-locked loop (PLL) is an interesting device. As shown in Figure 3-11, it consists of a phase detector, VCO, and low-pass filter. This comprises a servo loop, where the VCO is phase-locked to the input signal and oscillates at the same frequency. If there is a phase or frequency difference between the two sources, the phase detector ...

Webwhen the VCO is not locked to the reference. It should be mentioned that there exists a non-zero probability with which the PLL goes out of lock, even in the presence of small noise [18, 19]. This probability and the associated first exit time out of the basin of attraction (i.e., locked state) can also be calculated for these systems
WebIn a radio synthesizer adapted for use in an aircraft transceiver, an out of lock detector which enables or inhibits output from the synthesizer depending upon whether the synthesizer phase lock loop is in or out of lock. Under normal in lock operating conditions the oscillator output is coupled to the input of an output amplifier. When the loop is out of …

For the phase detector type shown (Gilbert multiplier or mixer), the voltage vs. phase slope reverses outside this range.
