Description and Introduction

3.3V, 2.0GHz ANY DIFF. IN-TO-LVDS PROGRAMMABLE CLOCK DIVIDER FANOUT BUFFER W/ INTERNAL TERMINATION The SY89873LMI is a high-speed, low-power 1:5 LVCMOS fanout buffer manufactured by Microchip Technology (formerly Micrel). Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage (VCC):** 2.375V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Type:** LVCMOS/LVTTL  
- **Output Type:** LVCMOS  
- **Maximum Clock Frequency:** 1.5GHz  
- **Propagation Delay:** 300ps (typical)  
- **Output Skew (Part-to-Part):** 50ps (typical)  
- **Additive Jitter (RMS):** <0.3ps (typical)  
- **Power Consumption:** 60mW (typical) at 3.3V  

### **Descriptions:**
- The SY89873LMI is a 1:5 fanout buffer optimized for high-speed clock and data signal distribution.  
- It provides low skew and low jitter performance, making it suitable for telecommunications, networking, and computing applications.  
- The device supports a wide input voltage range and is compatible with LVCMOS/LVTTL signal levels.  

### **Features:**
- **High-Speed Operation:** Supports frequencies up to 1.5GHz.  
- **Low Power Consumption:** Typically 60mW at 3.3V.  
- **Low Additive Jitter:** <0.3ps RMS for clean signal integrity.  
- **Low Output Skew:** 50ps typical for synchronized outputs.  
- **Wide Supply Range:** Operates from 2.375V to 3.6V.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **Packaging:** 16-pin 3x3mm QFN (MLF).  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

3.3V, 2.0GHz ANY DIFF. IN-TO-LVDS PROGRAMMABLE CLOCK DIVIDER FANOUT BUFFER W/ INTERNAL TERMINATION

Alternative Part Number

  • NB6L11DTG --: Pin-compatible 1:2 differential fanout buffer with similar LVPECL/CML signaling and low skew, suitable drop-in replacement in most clock distribution designs.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer from a different series, offering comparable output drive and propagation delay for clock fanout applications.
  • ADCLK944BCPZ --: High-performance 1:4 LVPECL clock fanout buffer that can replace the SY89873LMI when additional outputs are acceptable, with low additive jitter.
  • NB7L86MMNG --: Differential clock/data fanout buffer with similar low-voltage differential signaling function and comparable package, suitable as a functional replacement.
  • ICS8535AG-01LF --: Low-skew clock fanout buffer offering similar differential output drive and supply range, commonly used as a cross-reference for Micrel fanout parts.
  • CDCLVC1104PW --: Low-jitter clock buffer/fanout device with comparable differential signaling support and small package, usable as an alternative with design verification.
