Description and Introduction

Precision LVPECL 2:1 Multiplexer with 1:2 Fanout and Internal Termination The part **SY89473UMG** is manufactured by **MICREL**. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** MICREL  
- **Type:** High-Speed, Low-Power 1:10 LVCMOS/LVTTL Fanout Buffer  
- **Supply Voltage:** 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** LVCMOS/LVTTL  
- **Number of Outputs:** 10  
- **Input Frequency Range:** Up to 250MHz  
- **Propagation Delay:** Typically 2.5ns  
- **Package:** 24-pin QFN  

### **Descriptions:**  
- The SY89473UMG is a high-performance, low-power 1:10 fanout buffer designed for clock and data signal distribution.  
- It supports LVCMOS/LVTTL input levels and provides 10 identical outputs with minimal skew.  
- Suitable for applications requiring precise signal duplication, such as telecommunications, networking, and computing systems.  

### **Features:**  
- **Low additive jitter** for high signal integrity  
- **3.3V operation** with low power consumption  
- **1:10 fanout** with minimal output-to-output skew  
- **Wide input frequency range** (up to 250MHz)  
- **Industrial temperature range** (-40°C to +85°C)  
- **Small footprint** (24-pin QFN package)  

This information is based solely on the available knowledge base for **SY89473UMG**.

Application Scenarios & Design Considerations

Precision LVPECL 2:1 Multiplexer with 1:2 Fanout and Internal Termination

Alternative Part Number

  • NB6L72MNG --: Dual differential 2:1 multiplexer in the same QFN package family with similar 2.5V/3.3V LVPECL/CML signaling, a common drop-in style replacement for Micrel SY89 series muxes.
  • NB6L72MNR2G --: Same NB6L72 differential mux core as above, offered in tape-and-reel form; electrically compatible with SY89473UMG for 2:1 differential signal routing.
  • MAX9372EUP --: Differential 2:1 multiplexer with LVPECL-compatible outputs in a small package, usable as a functional alternative when the exact Micrel footprint is not mandatory.
  • MC100EP57MNG --: Differential 2:1 multiplexer in the ECL/PECL family with comparable speed and function, suitable as a functional substitute when logic levels are matched.
  • ADCLK854BCPZ --: High-speed clock fanout/multiplexer with differential outputs, offering similar signal routing capability for clock distribution applications.
