Description and Introduction

PLL Frequency Synthesizer for Electronic Tuning in Car Stereo Tuners The LC72191 is a PLL frequency synthesizer IC manufactured by SANYO.  

### **Specifications:**  
- **Operating Voltage:** 2.7V to 5.5V  
- **Frequency Range:** Supports RF and local oscillator (LO) frequencies up to several hundred MHz (exact range depends on external components).  
- **Phase Comparator:** Built-in phase comparator for stable frequency control.  
- **Serial Interface:** Uses a serial data input for programming frequency division ratios.  
- **Low Power Consumption:** Designed for battery-operated applications.  
- **Package:** Typically available in SOP (Small Outline Package) or other surface-mount packages.  

### **Descriptions and Features:**  
- The LC72191 is a CMOS-based PLL frequency synthesizer IC used in radio communication systems, such as car radios, tuners, and other RF applications.  
- It integrates a programmable divider, phase comparator, and charge pump for frequency synthesis.  
- Supports fractional-N synthesis for finer frequency resolution.  
- Includes a lock detect function to indicate when the PLL is locked to the desired frequency.  
- Compatible with microcontroller interfaces for easy frequency tuning.
