Product Description

The MAX4890ETJ+ is a 10/100/1000 base-T Ethernet LAN switch in 32 pin TQFN package. This device switch the signals from two interface transformers and connect signals to a single 10/100/1000 base-T Ethernet PHY, simplifying docking station design and reducing manufacturing costs. It can also route signals from a common interface transformer to two different boards in board redundancy applications. Switch provides an extremely low capacitance and on-resistance to meet Ethernet insertion and return-loss specifications. It is used in notebooks and docking stations, servers and routers with Ethernet interfaces, board level redundancy protection, SONET/SDH signal routing, T3/E3 redundancy protection and video switching.
Supply voltage range is 3V to 3.6V
Operating temperature range from -40°C to 85°C
Low on-resistance (RON) of 4ohm (typ) & 5.5ohm (max) at TA = +25°C
Ultra-low on-capacitance (CON) of 6.5pF (typ)
Low < 200ps bit to bit skew
1GHz -3dB bandwidth
Optimized pin-out for easy transformer and PHY interface
Low 450µA (max) quiescent current
Bidirectional 8 to 16 multiplexer/demultiplexer
