NB4L6254MNR4G

Clock Buffers, Drivers Overview

The NB4L6254MNR4G is a high-performance clock buffer and distribution IC manufactured by onsemi. It features a single differential input that fans out to six LVPECL outputs, providing a 1:6 split ratio. The device supports maximum output frequencies up to 3 GHz with low propagation delay characteristics. It operates within a supply voltage range of 2.375 V to 3.465 V and is housed in a compact 32-VFQFN package with exposed pad for efficient thermal management.
