Overview
The NB3L204KMNTXG is a clock fanout buffer IC produced by onsemi, formerly known as AMI Semiconductor and PulseCore Semiconductor. This component is designed to distribute clock signals with high accuracy and low skew. It operates as a 1:4 fanout buffer, meaning it takes one input clock signal and generates four identical output clock signals. The device is optimized for ultra-low phase noise, propagation delay variation, and low output-to-output skew, making it suitable for various high-speed applications.
The NB3L204KMNTXG is packaged in a 24-pin QFN (4x4 mm) exposed pad package, which enhances thermal performance. It is lead-free and RoHS compliant, ensuring environmental sustainability and compliance with industry regulations.
