Description and Introduction

2.5V/3.3V TWO INPUT, 1GHz LVTTL/CMOSTO-LVPECL 1:4 FANOUT BUFFER/TRANSLATOR WITH 2:1 INPUT MUX The SY89834UMI is a high-speed, low-power 1:4 LVCMOS fanout buffer manufactured by MICREL (now part of Microchip Technology).  

### **Specifications:**  
- **Supply Voltage (VCC):** 3.3V ±10%  
- **Input Type:** LVCMOS  
- **Output Type:** LVCMOS  
- **Number of Outputs:** 4  
- **Maximum Clock Frequency:** 1.5 GHz  
- **Propagation Delay:** 500 ps (typical)  
- **Output-to-Output Skew:** 50 ps (typical)  
- **Input-to-Output Skew:** 100 ps (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin MLF (3mm x 3mm)  

### **Descriptions:**  
- The SY89834UMI is designed for high-speed clock and signal distribution.  
- It provides low additive jitter and low skew for precision timing applications.  
- The device operates from a single 3.3V supply and is optimized for low power consumption.  

### **Features:**  
- **High-Speed Operation:** Supports frequencies up to 1.5 GHz.  
- **Low Power Consumption:** Typically 45 mA at 3.3V.  
- **Low Additive Jitter:** < 0.5 ps RMS (12 kHz – 20 MHz).  
- **Wide Input Voltage Range:** Compatible with various LVCMOS levels.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **Small Footprint:** 8-pin MLF package for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

2.5V/3.3V TWO INPUT, 1GHz LVTTL/CMOSTO-LVPECL 1:4 FANOUT BUFFER/TRANSLATOR WITH 2:1 INPUT MUX

Alternative Part Number

  • NB6L72MNG --: Pin-compatible differential clock/data translator with similar fanout buffer function and comparable supply voltage and speed, widely available as a drop-in functional replacement.
  • ICS8535AG-01LF --: Low-skew clock fanout buffer offering similar output drive and frequency capability, suitable for replacing the SY89834 in clock distribution designs.
  • CDCLVC1104PWR --: Low-jitter clock buffer with comparable fanout and supply range, providing a functional alternative when layout adjustments are acceptable.
  • NB6L11SMNG --: Differential fanout buffer in the same functional class as the SY89834, with similar low-voltage differential signaling support and a different naming series.
  • CDCLVC1104PW --: Low-jitter clock fanout buffer offering comparable multi-output clock distribution, from a different vendor and series.
  • PI6C4901AZHE --: Clock buffer/fanout device with similar differential clock distribution role, providing a distinct part family as an alternative source.
