PLL with LM, How does this circuit work?

Tags Phase Locked Loop. You can end up with a lag, or worst case the loop will break lock and put out meaningless information. Now consider no input is given, under such case lm5655 VCO will be in free running mode generating signal whose frequency is determined by the capacitor and resistor connected at the pin 8 and pin 9.

The product detector creates ,m565 output signal which is proportional to the phase difference rather than to the difference of both frequencies. Hi hkBattousai, datsheet you were interested in the pull-in action, attached please find a pdf document showing this process as a simulation result. The input signal goes in to the phase detector along with VCO feedback and this phase detector compares whether both signal are in same phase or frequency.

Can you explain it please?

I have two questions to ask: From my signal courses I remember that in order to talk about the phase difference of two signals their magnitude spectrum must be same.

TL — Programmable Reference Voltage.

You say that the output voltage level is proportional with the phase difference. It looks like they use pin 1 as a single ended input, and ground pin 2, for most applications. This output voltage of PD is given to amplifier to amplify the voltage signal and the amplified voltage is given to VCO, which generates waveform whose frequency depends on magnitude of the given input voltage. Pin 4 and 5 are connected in order to feed the detector output to the VCO input.

In the device pin 2 and pin3 are inputs where we can connect the input analog signal but usually pin 3 will be grounded and pin2 is used dataxheet input. CMOS Technology file 1. Equating complex number interms of the other 6. Part and Inventory Search. Is there datassheet necessary to correct or add? It looks like there is NOT a frequency detector portion for the phase detector, so the lock-in range is limited.

This is how a phase locked loop worksthe VCO output signal frequency will always tries to keep up with the input signal frequency. The VCO will increase or decrease the signal frequency depending of the fed voltage of amplifier. I think the figure is selfexplaining. Originally Posted by hkBattousai.

Q1 Is my explanation above correct? Which program can simulate the LM? Pin Configuration LM is a 14 pin device and the function of each pin is stated below. How do you get an MCU design to market quickly?

If you monitor the tuning voltage going to the onboard VCO, you can crudely guess the external source’s frequency by simpliy measuring the tuning voltage. If they are in phase or frequency the PD provides zero voltage output and if phase or frequency is present the PD provides ,m565 output voltage.

How reliable is it? As the external signal sources frequency SLOWLY moves up, for instance, the onboard VCO will sense an instantaneous phase error between its two inputs, and automatically try to correct the phase error. Can I leave the 4th, 8th and 9th pins not connected? Of course, if the external source frequency moves too far or too fast, the control loop will not be able to keep up.

PNP transistor not working 2. Once the adjustment is done both the input signal frequency and VCO frequency will match.
