Description and Introduction

MECL PLL COMPONENTS ?0/21 DUAL MODULUS PRESCALER The MC12019D is a high-speed prescaler manufactured by ON Semiconductor. It is designed for use in frequency synthesis applications, particularly in phase-locked loop (PLL) circuits.  

### **Specifications:**  
- **Frequency Range:** 1.1 GHz to 2.2 GHz  
- **Division Ratio:** 128/129 (programmable)  
- **Supply Voltage:** 4.5 V to 5.5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-8  

### **Descriptions and Features:**  
- High-speed ECL-compatible prescaler  
- Low power consumption  
- Programmable divide-by-128/129 operation  
- Single-ended or differential clock input  
- Suitable for wireless communication systems and RF applications  
- Compatible with standard ECL logic levels  

The MC12019D is commonly used in frequency synthesizers for applications such as satellite communication, radar systems, and test equipment.

Application Scenarios & Design Considerations

Alternative Part Number

  • SN74LS624N --: Voltage-controlled oscillator in a similar DIP package, widely available and functionally comparable for many VCO applications.
  • CD4046BE --: Classic CMOS phase-locked loop with built-in VCO, a common substitute when the original PLL/VCO function is needed.
  • NE555P --: General-purpose timer usable as a simple oscillator in DIP-8, suitable only for basic timing/oscillator needs as a fallback.
