Description and Introduction

Phase Locked Loop The LM565H is a phase-locked loop (PLL) IC manufactured by National Semiconductor (NS). Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Phase-Locked Loop (PLL) IC  
- **Operating Voltage Range:** ±6V to ±12V (dual supply)  
- **Operating Frequency Range:** Up to 500 kHz  
- **VCO Frequency Range:** Adjustable via external components  
- **Input Sensitivity:** Typically 10 mV RMS for lock  
- **Power Dissipation:** 750 mW (max)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**
- The LM565H is a general-purpose PLL IC designed for frequency demodulation, frequency synthesis, and FM/PM demodulation.  
- It consists of a voltage-controlled oscillator (VCO), a phase comparator, and an amplifier.  
- The device is housed in a TO-5 metal can package.  

### **Features:**
- **Wide Operating Voltage Range:** Supports dual supplies from ±6V to ±12V.  
- **Adjustable VCO Frequency:** Set using external resistors and capacitors.  
- **High Stability:** Temperature-compensated VCO for stable operation.  
- **Low Frequency Drift:** Minimized drift due to internal compensation.  
- **High Input Sensitivity:** Capable of locking onto weak signals.  

These details are based on the manufacturer's datasheet and specifications.
