MAXIM MAX3840 +3.3V 2.7Gbps Dual 2 2 Crosspoint Switch handbook
Update: 01 October, 2023
The MAX3840 is a MAXIM high-performance dual 2×2 asynchronous crosspoint switch for SDH/SONET DWDM and other high-bandwidth data switching applications, suitable for OC-48 systems with forward error correction. It features high bandwidth, fully differential signal path, which minimizes jitter accumulation, crosstalk and signal skew. Each 2×2 crosspoint switch can fan out and/or multiplex up to 2.7Gbps data and 2.7GHz clock signals. All inputs and outputs are compatible with current mode logic (CML) and can be easily adapted 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. 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×5mm footprint) and operates from a +3.3V supply over a temperature range of -40°C to +85°C.
