Part Manufacturer: Maxim


Part Description: MAX3840 DS

Part Details:

19-1854; Rev 5; 9/07 +3.3V, 2.7Gbps Dual 2 2 Crosspoint Switch MAX3840 General Description Features The MAX3840 is a dual 2 2 asynchronous crosspoint Single +3.3V Supply switch for SDH/SONET DWDM and other high-speeddata switching applications where serial data stream 460mW Power Consumption loop-through and protection channel switching are 2psRMS Random Jitter required. It is ideal for OC-48 systems with forwarderror correction. A high-bandwidth, fully differential sig- 7psP-P Deterministic Jitter nal path minimizes jitter accumulation, crosstalk, and Power-Down Feature for Deselected Outputs signal skew. Each 2 2 crosspoint switch can fan outand/or multiplex up to 2.7Gbps data and 2.7GHz clock CML Inputs/Outputs signals. All inputs and outputs are current mode logic 6ps Channel-to-Channel Skew (CML) compatible and easily adaptable to interfacewith an AC-coupled LVPECL signal. When not used, 100ps Output Edge Speed each CML output stage can be powered down with an 5mm 5mm 32 QFN or Thin QFN Package enable control to conserve power. The typical powerconsumption is 460mW with all outputs enabled. The MAX3840 is compatible with the MAX38762.5Gbps clock and data recovery (CDR) circuit. The MAX3840 is available in a 32-pin exposed-pad Ordering Information QFN package (5mm 5mm footprint) and operates PIN - PK G from a +3.3V supply over a temperature range of -40°C PART TEMP RANGE PA C K A G E C O D E to +85°C.
