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. Maxim’s MAX4890 switches can provide extremely low capacitance and on-resistance to meet Ethernet insertion and return-loss specifications.

Ethernet Switch IC’s

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.

Features and Benefits

• Single +3.0V to +3.6V Power-Supply Voltage
• Low On-Capacitance: 6.5pF
• Low < 200ps Bit-to-Bit Skew
• Built-In LED Switches for Switching Indicators to Docking Station
• Low On-Resistance (RON): 4Ω (typ), 6.5Ω (max)

Applications

• Board-Level Redundancy Protection
• Notebooks and Docking Stations
• Servers and Routers with Ethernet Interfaces
• SONET/SDH Signal Routing
• T3/E3 Redundancy Protection

Note

Please note that any defect or non – conformance of this product must be discovered and reported to RS within 20 days of purchase.
