Description and Introduction

ULTRA-PRECISION 1:4 LVPECL FANOUT BUFFER/TRANSLATOR WITH INTERNAL TERMINATION The SY89831UMG is a high-performance, low-jitter clock fanout buffer manufactured by Microchip Technology (formerly Micrel).  

### **Specifications:**  
- **Supply Voltage:** 3.3V ±10%  
- **Input Frequency Range:** Up to 1.5GHz  
- **Output Frequency Range:** Up to 1.5GHz  
- **Number of Outputs:** 4 (LVPECL)  
- **Input Types:** LVPECL, LVDS, CML, LVCMOS  
- **Output Type:** LVPECL  
- **Additive Jitter (RMS):** <0.3ps (typical)  
- **Propagation Delay:** 1.3ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (3mm x 3mm)  

### **Descriptions:**  
The SY89831UMG is a 1:4 differential clock fanout buffer designed for high-speed applications requiring low jitter and high signal integrity. It supports multiple input types and provides LVPECL outputs with minimal skew.  

### **Features:**  
- **Low jitter performance** for high-speed clock distribution  
- **Wide input frequency range** (up to 1.5GHz)  
- **Multiple input compatibility** (LVPECL, LVDS, CML, LVCMOS)  
- **4 matched LVPECL outputs**  
- **Low additive jitter** (<0.3ps RMS)  
- **3.3V power supply**  
- **Industrial temperature range** (-40°C to +85°C)  
- **Small 16-pin QFN package** (3mm x 3mm)  

This device is commonly used in telecommunications, networking, and high-speed data transmission systems.

Application Scenarios & Design Considerations

ULTRA-PRECISION 1:4 LVPECL FANOUT BUFFER/TRANSLATOR WITH INTERNAL TERMINATION

Alternative Part Number

  • NB6L11MMNG --: Differential fanout buffer with similar low-skew performance and compatible logic family, available in the same QFN package style.
  • MC100EP11MNR4G --: ECL/PECL differential fanout buffer offering comparable speed and output drive, a common substitute in clock distribution designs.
  • SN65LVDS1DBVR --: High-speed differential driver/buffer with similar signaling characteristics, suitable when board-level rework or adapter is acceptable.
  • NB7L86MMNG --: Pin-compatible 2.5V/3.3V differential fanout buffer in the same QFN package family, with comparable output drive and jitter performance.
  • ICS8535AG-01LF --: Low-skew clock fanout buffer offering similar differential output capability and supply range, suitable as a functional replacement.
  • CDCLVC1104PW --: Low-jitter clock buffer with similar fanout function and wide supply range; requires layout review but is a viable alternative.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer with comparable bandwidth and output drive, widely available and electrically similar to the SY89831 family.
  • ADCLK854BCPZ --: High-speed clock fanout buffer offering similar differential output capability and low jitter performance, suitable as a functional replacement when layout is adjusted.
