While Proteus is a powerful tool for mixed-signal simulation, the LM565 may not always be present in the default library. 1. Checking the Library The is a classic general-purpose Phase-Locked Loop (PLL)

The LM565 integrates three primary functional blocks: a double-balanced , a highly stable Voltage-Controlled Oscillator (VCO) , and an internal amplifier. Checking the Library The LM565 integrates three primary

The LM565 is a monolithic Phase-Locked Loop (PLL) IC that contains a stable, highly linear Voltage-Controlled Oscillator (VCO), a phase detector, and an operational amplifier to serve as a loop filter. It operates from a single supply of +5V to +12V (or dual supplies up to ±12V), making it ideal for analog communication projects.
