Product Description

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
