Abstract
A method for changing operating frequency in a serial data link includes transmitting first datagrams over the serial data link using a first physical layer interface configured for a first frequency of operation, configuring a second physical layer interface for a second frequency of operation different from the first frequency of operation while the first datagrams are transmitted over the serial data link, transmitting configuration information over the serial data link using the first physical layer interface after the second physical layer interface has been configured for the second frequency of operation, idling the serial data link by terminating transmissions by the first physical layer interface, decoupling the first physical layer interface from the serial data link, coupling the second physical layer interface to the serial data link, and transmitting second datagrams over the serial data link using the second physical layer interface and the second frequency of operation.
