The NB4N840MMNR4G is a dual 2 x 2 crosspoint switch designed for high-speed applications, featuring a fully differential architecture that minimizes jitter, crosstalk, and signal skew. It supports a maximum input clock frequency of 2.7 GHz and a maximum data frequency of 3.2 Gb/s, making it suitable for SDH/SONET, DWDM, and Gigabit Ethernet applications. The device includes internally terminated differential CML inputs that accept AC-coupled LVPECL or direct coupled CML signals, eliminating the need for external components and minimizing interface reflections. With a typical propagation delay of 225 ps, rise and fall times of 80 ps, and channel-to-channel skew of just 7 ps, the NB4N840MMNR4G is optimized for performance. It operates within a voltage range of 3.0 V to 3.6 V and consumes approximately 430 mW of power. The device is housed in a compact 5 x 5 mm 32-pin QFN package and is Pb-free. It also features a power-saving mode with disabled outputs, enhancing its efficiency in various applications.
