الوصف
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.
