Description and Introduction

Tone Decoder The LM567CMX is a tone decoder manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Type:** Tone Decoder / Phase-Locked Loop (PLL)  
- **Operating Voltage:** 4.75V to 9V  
- **Operating Frequency Range:** 0.01Hz to 500kHz  
- **Low Frequency Drift with Temperature:** ±50ppm/°C  
- **High Output Sink Current:** Up to 100mA  
- **Bandwidth Adjustable:** Via external components  
- **Package Type:** SOIC-8  

### **Descriptions:**  
The LM567CMX is designed to detect a specific frequency within a given bandwidth. It consists of a phase-locked loop (PLL) with an integrated amplifier and comparator. When the input signal matches the internally set frequency (determined by external timing components), the output activates.  

### **Features:**  
- **Frequency Lock Detection:** Accurately locks onto and detects input tones.  
- **Adjustable Bandwidth:** Allows tuning for noise rejection.  
- **Stable Operation:** Low frequency drift over temperature variations.  
- **High Output Current:** Can directly drive relays, LEDs, or other loads.  
- **Wide Supply Voltage Range:** Suitable for battery-powered applications.  
- **Internal Amplifier:** Simplifies circuit design by reducing external components.  

This information is based on the manufacturer's datasheet.
