Description and Introduction

Low-Voltage Single-Chip Microcontrollers with On-Chip PLL and LCD Driver Circuits The LC72342G is a PLL frequency synthesizer IC manufactured by ON Semiconductor. Below are the factual specifications, descriptions, and features from the available knowledge base:

### **Specifications:**  
- **Supply Voltage (VCC):** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP (Small Outline Package)  
- **PLL Lock Range:** 30MHz to 76MHz (typical)  
- **Reference Frequency:** 7.2kHz, 9kHz, or 10kHz (selectable)  
- **Channel Step:** 5kHz, 6.25kHz, 9kHz, 10kHz, 12.5kHz, or 25kHz (programmable)  
- **Serial Data Interface:** 3-wire (CLK, DATA, CE)  

### **Description:**  
The LC72342G is a CMOS-based PLL frequency synthesizer IC designed for radio tuning applications, particularly in car audio systems. It integrates a prescaler, programmable divider, phase comparator, and charge pump to generate stable local oscillator signals for FM/AM tuners.

### **Features:**  
- Low-voltage operation (compatible with 3V and 5V systems)  
- Built-in 1/2 frequency divider for FM band  
- Auto-search function with up/down control  
- Station memory function (up to 6 channels)  
- Direct LED drive output for frequency display  
- Low standby current consumption  

This information is based solely on the manufacturer's datasheet and technical documentation.
