Description and Introduction

MECL PLL COMPONENTS ?2/33, ?4/65 DUAL MODULUS PRESCALER The MC12034AD is a high-speed prescaler integrated circuit (IC) manufactured by ON Semiconductor. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
ON Semiconductor  

### **Part Number:**  
MC12034AD  

### **Description:**  
The MC12034AD is a high-speed ECL (Emitter-Coupled Logic) prescaler designed for frequency division in RF and microwave applications. It is commonly used in phase-locked loops (PLLs), frequency synthesizers, and communication systems.  

### **Key Features:**  
- **Frequency Range:** Up to 1.1 GHz (typical operating frequency).  
- **Division Ratio:** Fixed divide-by-8/9 or divide-by-10/11 (programmable via control input).  
- **Logic Family:** ECL (Emitter-Coupled Logic) for high-speed operation.  
- **Supply Voltage:** -5.2V (standard ECL power supply).  
- **Package Type:** SOIC-8 (Surface Mount).  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade).  
- **Low Power Consumption:** Optimized for high-speed applications with minimal power dissipation.  
- **Applications:** Frequency synthesizers, RF communication systems, test equipment, and radar systems.  

### **Additional Notes:**  
- The MC12034AD is compatible with other ECL logic devices.  
- Requires proper termination for optimal performance in high-frequency circuits.  

This information is based solely on manufacturer datasheets and technical documentation.

Application Scenarios & Design Considerations

MECL PLL COMPONENTS ?2/33, ?4/65 DUAL MODULUS PRESCALER

Alternative Part Number

  • MC12034AP --: Same MC12034 prescaler family in a DIP package, electrically equivalent with only package difference.
  • MC12034ADG --: ON Semiconductor successor version of the same MC12034 device, same function and pinout.
  • MC12034ADR2 --: Tape-and-reel variant of the same MC12034 prescaler, identical electrical specifications.
  • SN74LS624N --: Voltage-controlled oscillator in a similar function class, widely available and easy to source as a replacement for the MC12034A VCO.
  • 74HC4046AN --: Phase-locked loop with built-in VCO, commonly used where the MC12034A oscillator function is needed; different series and well stocked.
  • CD4046BE --: Classic CMOS PLL/VCO device offering comparable oscillator functionality, available in DIP package for drop-in style substitution.
