General Description

The MAX4927 meets the needs of high-speed differential switching, including that of Gigabit Ethernet (10/100/1000) Base-T switching as well as LVDS and LVPECL switching. The MAX4927 provides enhanced ESD protection up to ±15kV and excellent high-frequency response, making the device especially useful for interfaces that must go to an outside connection.
