Description
The MAX3840 is a dual 2 x 2 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. When not used, each CML output stage can be powered down with an enable control to conserve power. The typical power consumption is 460mW with all outputs enabled.

The MAX3840 is compatible with the MAX3876 2.5Gbps clock and data recovery (CDR) circuit.

The MAX3840 is available in a 32-pin exposed-pad QFN package (5mm x 5mm footprint) and operates from a +3.3V supply over a temperature range of -40°C to +85°C.

An evaluation kit is available:  MAX3840EVKIT
