MAX3840ETJ+

The MAX3840ETJ+ is a +3.3V, 2.7Gbps dual 2 x 2 crosspoint switch in 32 pin TQFN package. This asynchronous crosspoint switch for SDH/SONET DWDM and other high speed data switching applications where serial data stream loop through and protection channel switching are required. It is ideal for OC-48 systems with forward error correction. A high bandwidth, fully differential signal path minimizes jitter accumulation, crosstalk and signal skew. Each 2 x 2 crosspoint switch can fan out and/or multiplex up to 2.7Gbps data and 2.7GHz clock signals. All inputs and outputs are current mode logic (CML) compatible and easily adaptable to interface with an AC-coupled LVPECL signal. It is compatible with the MAX3876 2.5Gbps clock and data recovery (CDR) circuit. It is used in SDH/SONET and DWDM transport systems, add drop multiplexers, ATM switch cores, WDM cross-connects and high speed backplanes.
