Description and Introduction

3.3V / 5V ECL ÷2/4, ÷4/5/6 Clock Generation Chip The MC100EP139DWR2 is a high-speed differential 1:5 clock distribution chip manufactured by Motorola (MOTO).  

### **Specifications:**  
- **Logic Family:** ECL (Emitter-Coupled Logic)  
- **Number of Outputs:** 5  
- **Input Type:** Differential  
- **Output Type:** Differential  
- **Supply Voltage:** -3.0V to -5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-20 (DWR2)  
- **Propagation Delay:** Typically 400ps  
- **Maximum Clock Frequency:** >1GHz  

### **Descriptions:**  
The MC100EP139DWR2 is designed for high-performance clock distribution applications, providing low skew and high-speed operation. It accepts a differential input and distributes it to five differential outputs with minimal jitter.  

### **Features:**  
- **Low Output Skew:** Ensures precise timing in high-speed systems.  
- **High-Speed Operation:** Supports clock frequencies exceeding 1GHz.  
- **Differential Inputs/Outputs:** Improves noise immunity and signal integrity.  
- **Wide Operating Voltage Range:** Compatible with -3.0V to -5.5V supplies.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  

This device is commonly used in telecommunications, networking, and high-speed computing applications.

Application Scenarios & Design Considerations

3.3V / 5V ECL ÷2/4, ÷4/5/6 Clock Generation Chip

Alternative Part Number

  • SY100EP139VZG --: Same ECL/PECL clock divider function in the 100EP family, available from Microchip (formerly Micrel) as a direct functional equivalent.
  • NB6L139MNG --: ON's own ECL clock divider with similar 2:1 divider architecture and ECL outputs, suitable as a same-vendor replacement.
  • MC100LVEP139DWR2 --: Low-voltage ECL variant of the same divider family with compatible pinout and function, usable when supply and logic levels permit.
  • NB100EP139MNG --: Direct functional equivalent ECL clock divider in the same EP139 family, offered by ON Semiconductor as a drop-in replacement with matching pinout.
  • MC100EP139DTG --: Same EP139 divider function from ON Semiconductor in a TSSOP package, usable as an alternative when the SOIC-wide package is not required.
