Overview
The NB3L553DR2G, produced by onsemi, is a low skew 1-to-4 clock fanout buffer designed for optimal clock distribution. This device is engineered to minimize output-to-output skew and device-to-device skew, making it ideal for applications requiring precise clock signals. The NB3L553DR2G operates over a wide voltage range of 2.375 V to 5.25 V and supports input/output clock frequencies up to 200 MHz.
