Abstract: A computer-implemented method includes using a transmitter to send data from the transmitter through a plurality of lanes to a receiver using a synchronous operation mode that includes sending the data from the transmitter through the plurality of lanes to the receiver in a synchronous transmission manner that relies on an alignment between a transmitter clock frequency and a receiver clock frequency. A synchronous operation performance analysis (SOPA) is performed during the synchronous operation mode. A switch from the synchronous operation mode to an asynchronous operation mode is made based on a result of performing the SOPA. The asynchronous operation mode includes sending the data from the transmitter through the plurality of lanes to the receiver without requiring alignment between the transmitter clock frequency and the receiver clock frequency.

Abstract: Embodiments of the invention are directed to a computer-implemented method of operating a data transmission system. The data transmission system includes a transmitter and a receiver. The computer-implemented method includes using the transmitter to send serialized data from the transmitter through a plurality of lanes to the receiver. The transmitter sends the serialized data at a first serialization ratio. The receiver is configured to receive and load the serialized data at a second deserialization ratio, wherein the first serialization ration is greater than the second deserialization ratio.
