Product Details
Maxim- MAX4890 Series
The MAX4890 series by Maxim Integrated contains high-speed analogue switches which meet the needs of 10/100/1000 Base-T applications. These uniquely designed devices are able to switch the signals from two interface transformers and are then able to connect the signals to a single of 10/100/1000 Base-T Ethernet PHY, this in itself simplifies docking station design and also reduces manufacturing costs.
The device is specially designed to also route signals from a common interface transformer to two different board in board-redundancy applications. Maxims MAX4890 switches can provide extremely low capacitance and on-resistance to meet Ethernet insertion and return-loss specifications.

Ethernet Switch ICs
Ethernet switch ICs are electrical components that provide control and switching capabilities to ethernet switches. They are usually attached to the circuit board of an ethernet switch and work together with the power supply and fans to ensure optimum switching.
