Abstract
A physical layer transceiver and a network node including the transceiver. The transceiver includes a media independent interface, a converter circuit block comprising circuitry configured to convert digital signals to analog signals for transmission over a network communications medium and convert analog signals received over the medium to digital signals, and one or more processing blocks configured to process digital data communicated between the media independent interface and the converter circuit block according to a network protocol. Management and control circuitry including power management circuitry and reset circuitry are provided. The transceiver further includes at least one single event effect (SEE) monitor, such as an ambience monitor, a configuration register monitor, a state machine monitor, or a phase locked loop (PLL) lock monitor, configured to detect and respond to an SEE event in the transceiver.
