Description and Introduction

2.5GHz ANY DIFF. IN-TO-LVPECL PROGRAMMABLE CLOCK DIVIDER/FANOUT BUFFER WITH INTERNAL TERMINATION The SY89874UMG is a high-speed, low-power differential 1:4 fanout buffer manufactured by **ＭＩＣＲＥＬ**.  

### **Key Specifications:**  
- **Supply Voltage:** 3.3V ±10%  
- **Input Type:** Differential (LVPECL, CML, LVDS compatible)  
- **Output Type:** Differential LVPECL  
- **Operating Frequency:** Up to 3.2GHz  
- **Propagation Delay:** ~300ps (typical)  
- **Additive Jitter:** <0.1ps RMS (typical)  
- **Power Consumption:** ~100mW (typical)  
- **Package:** 16-pin QFN (3mm x 3mm)  

### **Descriptions and Features:**  
- Provides **1:4 differential fanout** with low skew.  
- Supports **multiple input types** (LVPECL, CML, LVDS).  
- **Low additive jitter** for high-speed clock/data distribution.  
- **3.3V operation** with internal termination for LVPECL inputs.  
- **Industrial temperature range** (-40°C to +85°C).  
- **Applications:** Clock distribution, high-speed networking, and telecommunications.

Application Scenarios & Design Considerations

2.5GHz ANY DIFF. IN-TO-LVPECL PROGRAMMABLE CLOCK DIVIDER/FANOUT BUFFER WITH INTERNAL TERMINATION

Alternative Part Number

  • NB7L86MMNG --: Differential clock/data fanout buffer in the same 2.5V/3.3V CML/LVDS class, functionally similar to the SY89874U and available in a comparable QFN package.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer with similar high-speed signaling role; a well-established alternative when exact pinout is not critical.
  • ADCLK846BCPZ --: Low-jitter 1:6 clock fanout buffer covering similar high-speed clock distribution needs, usable as a functional substitute with layout adaptation.
  • NB6L11MMNG --: Pin-compatible 2.5V/3.3V differential clock fanout buffer in the same QFN package class, widely available and functionally equivalent for clock distribution.
  • CDCLVC1102PW --: Low-jitter LVCMOS clock buffer with similar fanout function and supply range, suitable as a drop-in functional replacement in most clock tree designs.
  • ICS8543BGI --: Differential-to-LVCMOS clock fanout buffer offering comparable output count and frequency support, commonly used as an alternative to Micrel clock distribution parts.
