Abstract
In a communication system comprising first and second nodes, a multilevel amplitude modulated signaling technique is utilized. The first and second nodes may communicate over a Fibre Channel link or other medium. The first and second nodes comprise respective transmitter and receiver pairs, with the transmitter of the first node configured for communication with the receiver of the second node and the receiver of the first node configured for communication with the transmitter of the second node. The first node is configured to generate a signal for transmission over a serial data channel to the second node, the signal having a multilevel amplitude modulated format in which, within a given clock cycle of the signal, multiple bits are represented by a given signal level.
