MAXIM INTEGRATED / ANALOG DEVICES MAX4890ETJT Ethernet Switch
The MAX4890ETJ+T from Maxim Integrated Products is a high-speed, bidirectional switch designed for Ethernet LAN applications. Packaged in a 32-pin TQFN, it facilitates 10/100/1000 Base-T Ethernet connections by switching signals from interface transformers to a single Ethernet PHY, simplifying device design and reducing manufacturing costs. The switch features very low on-resistance and capacitance, ensuring compliance with Ethernet insertion and return-loss specifications. It is suitable for notebooks, docking stations, servers, routers, and other telecommunication equipment requiring signal routing, redundancy, or video switching. Operating from a +3V to +3.6V power supply within a temperature range of -40°C to 85°C, it offers low crosstalk (-45dB at 1MHz), minimal insertion loss (0.6dB at 1MHz), and a bandwidth of 1GHz. It also provides board-level redundancy protection, with optimized pin configurations for easy transformer and PHY interfacing.
