Description and Introduction

Single-Chip Microcontrollers with Built-In LCD Driver and PLL Circuits The LC72338 is a PLL frequency synthesizer IC manufactured by SANYO. Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Type:** PLL Frequency Synthesizer IC  
- **Package:** Likely available in SOP (Small Outline Package) or other standard IC packages (exact package depends on variant).  
- **Operating Voltage:** Typically operates at **3V to 5.5V** (exact range may vary).  
- **Frequency Range:** Designed for RF applications, often used in **FM/AM tuners** or communication devices.  
- **Channels:** Supports multiple channel steps (e.g., **10 kHz, 50 kHz, 100 kHz**).  
- **Interface:** Serial data input (compatible with microcontrollers).  

### **Descriptions:**  
- The **LC72338** is a **CMOS-based PLL synthesizer** IC primarily used in radio frequency (RF) tuning systems, such as car stereos or communication equipment.  
- It integrates a **phase-locked loop (PLL)** circuit for stable frequency generation and tuning.  
- Often paired with a **prescaler** and **microcontroller** for channel selection.  

### **Features:**  
1. **Low Power Consumption:** CMOS technology ensures efficient operation.  
2. **Wide Frequency Coverage:** Suitable for **FM/AM band tuning**.  
3. **Serial Data Control:** Allows easy interfacing with microcontrollers.  
4. **High Stability:** PLL-based design ensures accurate frequency locking.  
5. **Built-in Prescaler:** Supports different frequency division ratios.  

For exact electrical characteristics, refer to the official **SANYO datasheet** (part number **LC72338**).
