Description and Introduction

Dual Modulus Prescaler The part MC12019 is manufactured by Motorola. Here are the specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Motorola  
- **Type:** Prescaler  
- **Input Frequency Range:** Up to 1.2 GHz  
- **Division Ratio:** 64/65 or 128/129 (selectable)  
- **Supply Voltage:** Typically 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (Surface Mount)  

### **Descriptions and Features:**  
- The MC12019 is a high-speed prescaler designed for frequency division in RF and communication applications.  
- It supports dual-modulus division ratios (64/65 or 128/129), making it suitable for phase-locked loop (PLL) synthesizers.  
- Low power consumption and high-speed operation make it ideal for wireless and broadband systems.  
- The device is optimized for use with Motorola’s PLL frequency synthesizer ICs.  
- It features a differential input for improved noise immunity and signal integrity.

Alternative Part Number

  • SN74LS624N --: Voltage-controlled oscillator in a similar function class, widely available and easy to source as a functional substitute.
  • CD4046BE --: Phase-locked loop/VCO IC that can replace the oscillator function in many designs, with broad availability and low cost.
  • NE566N --: Classic VCO IC offering comparable oscillator functionality for legacy designs, though availability may be limited.
  • SN74LS628N --: Voltage-controlled oscillator in a similar function class, widely available and pin-compatible in many designs.
  • MC1648P --: Emitter-coupled oscillator IC from the same vendor family lineage, commonly used where MC12019 oscillators were applied.
  • 74HC4046AN --: Phase-locked loop with built-in VCO, a flexible functional substitute for oscillator/PLL circuits using the MC12019.
