NB3N551DG

Clock Buffers, Drivers Overview

The NB3N551DG is a 3.3 V / 5.0 V ultra-low skew 1:4 clock fanout buffer manufactured by onsemi. Designed for high-speed digital applications, this device accepts a single differential or single-ended input and provides four low-skew buffered outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports input frequencies up to 200 MHz. The component is housed in an 8-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports both differential (LVPECL/LVDS) and single-ended (LVCMOS/LVTTL) input signals
• Provides four buffered outputs with adjustable output swing for flexible interface compatibility
• Operates on a single 3.3 V or 5.0 V power supply

Clock Buffers, Drivers Applications

• High-performance computing systems requiring distributed clocking
• Telecommunications infrastructure equipment
• Network switches and routers
• Test and measurement instruments
