PLL FM demodulator (LM565CN, RC4558DN)
Source: InternetPublisher:明天见 Keywords: Demodulator Updated: 2024/08/30
As shown in the figure, the circuit uses LM565CN to form a 10kHz±3kHz FM demodulation circuit. The differential demodulation output of V1 and V2 is level-shifted and amplified by the A1 differential amplifier in Figure (b), and then the active LPF formed by A2 filters out the 20kHz pulsation component.
