General Description The MAX4890/MAX4891/MAX4892 high-speed analog switches meet the needs of 10/100/1000 Base-T applications. These devices switch the signals from two interface transformers and connect the signals to a single 10/100/1000 Base-T Ethernet PHY, simplifying docking station design and reducing manufacturing costs. The MAX4890/MAX4891/MAX4892 can also route signals from a common interface transformer to two different boards in board-redundancy applications. Features ? Single +3.0V to +3.6V Power-Supply Voltage ? Low On-Resistance (RON): 4Ω (typ), 6.5Ω (max) ? Ultra-Low On-Capacitance (CON): 6.5pF (typ) ? Low < 200ps Bit-to-Bit Skew ? -3dB Bandwidth: 1GHz ? Optimized Pin-Out for Easy Transformer and PHY Interface ? Built-In LED Switches for Switching Indicators to Docking Station ? Low 450μA (max) Quiescent Current ? Bidirectional 8 to 16 Multiplexer/Demultiplexer ? Space-Saving Packages 32-Pin, 5mm x 5mm, TQFN Package 36-Pin, 6mm x 6mm, TQFN Package Applications Notebooks and Docking Stations Servers and Routers with Ethernet Interfaces Board-Level Redundancy Protection SONET/SDH Signal Routing T3/E3 Redundancy Protection Video Switching |
