MAX4890EETJ+ Description

Short technical summary and product information.

The MAX4890EETJ+ is an octal Ethernet switch IC from Analog Devices, designed to meet the demands of high-speed differential switching. It supports Gigabit Ethernet (10/100/1000) Base-T switching, as well as LVDS and LVPECL interfaces. This device provides enhanced ESD protection up to ±15kV, making it suitable for interfaces requiring external connections.

 

Key electrical characteristics include a low on-resistance of 4 Ohms typical and 6.5 Ohms maximum, with ultra-low on-capacitance of 8pF typical. It features a -23dB return loss at 100MHz and a -3dB bandwidth of 650MHz. The switch operates from a single +3.0V to +3.6V power supply and has a low quiescent current of 450µA maximum.

 

The MAX4890EETJ+ is available in a space-saving 32-pin, 5mm x 5mm TQFN package. It is designed for surface mount applications and operates within a temperature range of -40°C to +85°C. This component is ideal for applications such as notebooks, docking stations, servers, routers with Ethernet interfaces, board-level redundancy protection, SONET/SDH signal routing, and T3/E3 redundancy protection.
