The MAX4890E/MAX4892E meet the needs of high-speed differential switching. The devices handle the needs of Gigabit Ethernet (10/100/1000) Base-T switching as well as LVDS and LVPECL switching. The MAX4890E/MAX4892E provide enhanced ESD protection up to ±15kV, and excellent high-frequency response, making the devices especially useful for interfaces that must go to an outside connection.
Both devices provide extremely low capacitance (CON), as well as low resistance (RON), for low-insertion loss and very wide bandwidth. In addition to the four pairs of DPDT switches, the MAX4892E provides LED switching for laptop computer/docking station use.
The MAX4890E/MAX4892E are pin-for-pin equivalents to the MAX4890/MAX4892 and can replace these devices for those applications requiring the enhanced ESD protection. Both devices are available in space-saving TQFN packages and operate over the standard -40°C to +85°C temperature range.
Applications
- Board-Level Redundancy Protection
- Notebooks and Docking Stations
- Servers and Routers with Ethernet Interfaces
- SONET/SDH Signal Routing
- T3/E3 Redundancy Protection
