NB4N840MMNEVB: Dual 2x2 Crosspoint Switch Evaluation Board

The NB4N840M Evaluation Board is designed to provide a flexible and convenient platform for quickly evaluating, characterizing, and verifying the performance and operation of the NB4N840M Dual 2 x 2 Crosspoint Switch. The User Manual provides detailed information on the contents, layout, and use of the board. The manual should be used in conjunction with the NB4N840M datasheet, which contains complete technical details on the device specifications and operation. The NB4N840M is a high bandwidth fully differential dual 2 x 2 crosspoint switch with CML inputs/outputs for applications such as SDH/SONET DWDM and high-speed switching. Fully differential design techniques are used to minimize jitter accumulation, crosstalk, and signal skew, making the device ideal for loop and protection channel switching applications. Each 2 x 2 crosspoint switch can fan out and/or multiplex up to 3.2 Gb/s of data and 2.7 GHz clock signals.
