Abstract:
1. An apparatus for sending incoming data to a receiver over a digital communication channel having a multiplicity of lanes, each lane including a transmitter circuit and receiver circuit, the apparatus comprising: a transmitter buffer for temporarily storing the incoming data prior to transmission over said digital communication channel and having a fill level indicative of a volume of data to send; transmitter power logic responsive to the fill level of said transmitter buffer to determine a number of lanes required to provide a desired bandwidth for data communication and to place each lane of the multiplicity of lanes into either an inactive low-power state for power saving operation or an active powered up state for normal operation in accordance with the number of lanes; and transmit formatting logic for distributing the incoming data in accordance with a striping algorithm over lanes that are in the active powered up state; wherein the transmit formatting logic is configured to distribute the incoming data in meta frames over the lanes that are in the active powered up state, each meta frame including a diagnostic word, a portion of the incoming data, skip word, a scrambler state word, and a synchronization word; and wherein said transmitter power logic is configured to:
