Description and Introduction

Direct PLL Frequency Synthesizer for Electronic Tuning The LM7000 is a PLL (Phase-Locked Loop) frequency synthesizer IC manufactured by SANYO. Below are its specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -20°C to +75°C  
- **Frequency Range:** Supports tuning in the VHF and UHF bands (exact range depends on external components)  
- **Package Type:** SOP (Small Outline Package), likely SOP16 or similar  
- **Power Consumption:** Low power consumption typical of PLL synthesizers  

### **Descriptions:**  
- The LM7000 is designed for frequency synthesis in radio and TV tuners, enabling precise channel selection.  
- It integrates a phase comparator, programmable divider, and reference oscillator, requiring minimal external components.  
- Often used in analog tuners for stable local oscillator (LO) generation.  

### **Features:**  
- **Built-in Prescaler:** Supports divide ratios for high-frequency input signals.  
- **Serial Data Input:** Allows microcontroller-based frequency programming.  
- **Low Phase Noise:** Suitable for stable RF applications.  
- **Standby Function:** Reduces power consumption when inactive.  

For exact pin configurations and application circuits, refer to the official SANYO datasheet (if available).
