Description and Introduction

1.5GHz Precision, LVDS 1:5 Fanout with 2:1 MUX and Fail Safe Input with Internal Termination The part **SY89847UMG** is manufactured by **Micrel** (now part of Microchip Technology).  

### **Specifications:**  
- **Type:** 3.3V Precision LVPECL/LVDS/LVCMOS-to-LVPECL 2:1 Input MUX/1:2 Fanout Buffer  
- **Supply Voltage:** 3.3V ±10%  
- **Input Types:** LVPECL, LVDS, LVCMOS  
- **Output Type:** LVPECL  
- **Operating Frequency:** Up to 2.5GHz  
- **Propagation Delay:** 250ps (typical)  
- **Output Skew:** 20ps (typical)  
- **Package:** 16-pin MLF (4mm x 4mm)  

### **Descriptions and Features:**  
- **High-Speed Operation:** Supports frequencies up to 2.5GHz.  
- **Flexible Inputs:** Accepts LVPECL, LVDS, and LVCMOS signals.  
- **Low Jitter:** Optimized for low additive jitter.  
- **Differential Outputs:** Provides LVPECL outputs for high-speed signal integrity.  
- **MUX/Fanout Function:** Can operate as a 2:1 multiplexer or 1:2 fanout buffer.  
- **Low Power Consumption:** Designed for efficient power usage.  
- **Industrial Temperature Range:** -40°C to +85°C.  

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

*(Note: Micrel was acquired by Microchip Technology in 2015, but the part retains its original Micrel branding.)*
