Abstract
A system for reducing electromagnetic interference emissions is described. The system can include a network interface card with an Ethernet controller circuit. The Ethernet controller circuit generates an Ethernet output signal that includes a pre-emphasis component and a data component. The Ethernet controller circuit monitors the Ethernet output signal and adjusts the levels of the pre-emphasis component and the data component to reduce the electromagnetic interference caused by the network interface card but still fit the requirements for valid Ethernet signals.
