Description and Introduction

Precision Low Power Differential 2:1 LVPECL MUX with Internal Termination The SY89852UMG is a high-speed, low-power differential receiver manufactured by MICREL (now part of Microchip Technology).  

### **Specifications:**  
- **Supply Voltage (VCC):** 3.3V ±10%  
- **Input Voltage Range (Differential):** 100mV to 1.5V  
- **Propagation Delay:** 300ps (typical)  
- **Maximum Data Rate:** 3.2Gbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin MLF (3mm x 3mm)  

### **Descriptions:**  
- The SY89852UMG is designed for high-speed data transmission applications.  
- It accepts differential input signals and provides a differential output.  
- Suitable for clock and data signal distribution in networking and telecommunications systems.  

### **Features:**  
- Low power consumption: 45mW (typical)  
- High-speed operation up to 3.2Gbps  
- Differential PECL input and output  
- Internal 50Ω input termination resistors  
- Fail-safe input for open or terminated inputs  
- Compatible with LVPECL, CML, and LVDS signal levels  

This information is based on the manufacturer's datasheet. For detailed technical specifications, refer to the official documentation.

Application Scenarios & Design Considerations

Precision Low Power Differential 2:1 LVPECL MUX with Internal Termination

Alternative Part Number

  • NB7L86MMNG --: Same function class (2.5V/3.3V differential LVPECL fanout buffer) in a similar QFN package, widely available and pin-compatible in many designs.
  • MAX9374EKA+T --: Differential LVPECL buffer/driver with comparable speed and supply range, suitable as a functional replacement with minor layout adjustments.
  • SN65LVDS100DGK --: High-speed differential signal buffer/repeater that can substitute in many clock distribution paths, though AC coupling and termination may need review.
  • NB6L11MMNG --: Differential clock/data driver in the same 2.5V/3.3V CML/LVDS class with similar fanout and package, a common drop-in for Micrel SY89xxx parts.
  • MC100EP16DG --: ECL/PECL differential receiver-driver with comparable speed and output structure, widely used as a functional substitute in high-speed clock distribution.
  • SN65LVDS1DBVR --: LVDS driver offering similar differential signaling performance and small SOT-23 package, suitable when a lower-cost LVDS interface replacement is acceptable.
