What is maximum free running frequency of VCO for PLL 565?
Characteristics of SE/NE 565 PLL IC. Operating frequency range : 0.001 Hz to 500 kHz. Operating voltage range : ± 6 to ± 12 V.
What is free running frequency of the VCO?
Without connecting any input signal, apply power and use an oscilloscope or frequency counter to measure the free- running frequency at VCO out. It should be close to f0 = 1.2/4RTCT ≈ 1360 Hz. Set your function generator to output a sine wave at the measured value of f0.
Which is the PLL IC?
IC phase locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator. An IC phase-locked loop generally consists of a phase detector, a loop filter, voltage controlled oscillator (VCO) and an amplifier.
What is the conversion ratio of the phase detector in 565 PLL?
1.4/π = 0.4458
Explanation: The conversion ratio of the phase detector of 565 PLL (Monolithic PLL) Kφ = 1.4/π = 0.4458.
Is a PLL IC?
What is PLL capture range?
Capture range in pll is the range of frequencies over which pll can acquire lock with an input signal. Lock range is the much narrow range of frequency over which pll gets locked with the input signal.
What are the features of IC 565?
Features of IC 565: 1) Extreme stability of center frequency typically 200ppm. 2) Wide range of operating voltage ±6V to ±12V. 3) Very high linearity of demodulated output typically 0.2%
What is lm565 IC?
LM565 is a general purpose PLL ( Phase Locked Loop) IC designed for demodulation, frequency multiplication and frequency division. The device mainly consists of two components, one is voltage controller oscillator and other is phase detector. In which VCO is designed for highly linear operation and PD with good carrier suppression.
How does the PLL IC 565 work?
The PLL IC 565 is usable over the frequency range 0.1 Hz to 500 kHz. It has highly stable centre frequency and is able to achieve a very linear FM detection. The output of VCO is capable of producing TTL compatible square wave. The dual supply is in the range of ±6V to ±12V. The IC can also be operated from single supply in the range 12V to 24V.
