MAX4890EETJ+T Description

Short technical summary and product information.

The MAX4890EETJ+T is a high-speed differential switching device from Analog Devices, designed for Gigabit Ethernet (10/100/1000) Base-T, LVDS, and LVPECL applications. It features enhanced ESD protection up to ±15kV, making it suitable for interfaces requiring external connections.

 

This switch boasts ultra-low on-capacitance (8pF typical) and low on-resistance (4Ω typical), ensuring low insertion loss and wide bandwidth. With a -3dB bandwidth of 650MHz and a return loss of -23dB at 100MHz, it is optimized for high-frequency performance.

 

The device operates from a single +3.0V to +3.6V power supply and has a low quiescent current of 450µA maximum. It is available in a space-saving 32-pin TQFN package (5mm x 5mm) and is designed for surface mounting.

 

Applications include notebooks, docking stations, servers, routers with Ethernet interfaces, board-level redundancy protection, SONET/SDH signal routing, T3/E3 redundancy protection, and LVDS/LVPECL switching.
