Description and Introduction

3.3V, 2.0GHz ANY DIFFERENTIAL IN-TO-LVDS PROGRAMMABLE CLOCK DIVIDER AND 1:2 FANOUT BUFFER W/ INTERNAL TERMINATION The SY89876LMG is a high-performance, low-power 3.3V differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator manufactured by **Microchip Technology (formerly Micrel)**.  

### **Key Specifications:**  
- **Supply Voltage (VCC):** 3.3V ±10%  
- **Input Types:** LVPECL, LVDS, CML  
- **Output Type:** LVTTL/LVCMOS  
- **Operating Frequency:** Up to 2.5GHz  
- **Propagation Delay:** 250ps (typical)  
- **Output Skew:** 50ps (typical)  
- **Input Common Mode Range:**  
  - LVPECL: VCC - 1.3V to VCC - 0.3V  
  - LVDS/CML: 0.05V to 2.4V  
- **Output Voltage Levels:**  
  - LVTTL: 0V (low), 3.3V (high)  
  - LVCMOS: 0V (low), 3.3V (high)  
- **Power Consumption:** 85mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (4mm x 4mm)  

### **Descriptions and Features:**  
- High-speed signal translation between differential (LVPECL/LVDS/CML) and single-ended (LVTTL/LVCMOS) logic levels.  
- Low additive jitter for high-frequency applications.  
- Internal 50Ω termination resistors for LVPECL inputs.  
- Single-ended LVTTL/LVCMOS output with programmable slew rate.  
- Supports fail-safe operation (output defaults to low when inputs are open or terminated).  
- Suitable for clock distribution, networking, and telecommunications applications.  

This device is designed for applications requiring high-speed data and clock signal translation with minimal power consumption.

Application Scenarios & Design Considerations

3.3V, 2.0GHz ANY DIFFERENTIAL IN-TO-LVDS PROGRAMMABLE CLOCK DIVIDER AND 1:2 FANOUT BUFFER W/ INTERNAL TERMINATION

Alternative Part Number

  • NB6L11MMNG --: Pin-compatible 2.5V/3.3V differential clock fanout buffer in the same QFN package class, with similar low-skew performance and widely available supply.
  • CDCLVC1102PW --: Low-jitter LVCMOS clock buffer offering comparable fanout and skew specifications, suitable as a functional substitute in clock distribution designs.
  • ICS854S006AGILF --: Differential clock fanout buffer with similar output count and low additive jitter, providing a viable cross-vendor replacement for clock tree applications.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer with similar signaling and performance, a common drop-in choice for clock distribution applications.
  • NB7L11MMNG --: Low-skew 1:2 differential clock/data fanout buffer offering comparable speed and output drive, suitable as a second-source alternative.
