Low-latency, high-availability and high-speed serdes interface having multiple synchronization modes

A computer system for automatically determining an operation mode of a data transmission system, the data transmission system comprising a transmitter and a receiver, the computer system comprising a memory communicatively coupled to a processor, wherein the processor is configured to implement processor operations comprising:

• controlling the transmitter to send data from the transmitter through a plurality of lanes to the receiver using a synchronous operation mode;
• wherein the synchronous operation mode comprises 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;
• performing a synchronous operation performance analysis (SOPA) on the data transmission system while the data transmission system is operating in the synchronous operation mode;
• and
• switching the data transmission system from the synchronous operation mode to an asynchronous operation mode based on at least in part on a result of performing the SOPA;
• wherein the asynchronous operation mode comprises 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.
