Abstract
A method of synchronizing a first transceiver with a second transceiver during a low power idle mode is disclosed for use in network communication devices. A LDPC counter, which initiates a count operation upon transition to PAM16 mode, serves as a master counter to determined when, based on predetermined count values, each channel reactivates from low power idle mode to active mode to generate and send a refresh signal. The transmitter and associated remote receiver both reactivate at the predetermined refresh period to process the refresh signal. Each transmitter/receiver pair has predetermined refresh periods during low power idle mode. The refresh signal is processed for maintain clock synchronization and for filter and equalizer adaptation.
