Phase Locked Loop
The LM565 is a general-purpose phase-locked loop (PLL) integrated circuit (IC) from National Semiconductor (NS). It is available in a dual in-line package (DIP-14). Description: The LM565 is a voltage-controlled oscillator (VCO) with a wide range of operating frequencies. It has an adjustable frequency range of 1 Hz to 100 kHz and a wide range of input voltages from 0 to 10 V. The LM565 also features a wide range of modulation options, including pulse-width modulation (PWM), frequency modulation (FM), and amplitude modulation (AM). Features: Wide range of operating frequencies (1 Hz to 100 kHz) Wide range of input voltages (0 to 10 V) Wide range of modulation options (PWM, FM, and AM) Low power consumption Low cost Applications: The LM565 is used in a variety of applications, including radio frequency (RF) communication systems, frequency synthesisers, frequency counters, and signal generators. It is also used in frequency-shift keying (FSK) and phase-shift keying (PSK) modulators. (For reference only)
