NB7L14MMNR2

Clock Buffers, Drivers Overview

The NB7L14MMNR2 is a differential 1:4 clock and data fanout buffer manufactured by onsemi. It translates differential CML inputs to four low-voltage positive emitter-coupled logic (LVPECL) outputs with internal termination resistors. The device operates at supply voltages of 2.5V or 3.3V, supporting maximum frequencies up to 7GHz and data rates of 10Gbps. It is housed in a QFN-32 package measuring 5x5mm with a 0.50mm pitch, designed for high-speed signal distribution in telecommunications and networking infrastructure.
