A transmitter device may communicate with a receiver device via one or more data links. Data transmitted over the data links may be conveyed in accordance with a communications protocol that requires a deterministic latency for all data lanes in each of the data links. The receiver device may include a deterministic latency controller configured to store a worst-case latency value acquired upon initial startup and a predetermined link reinitialization latency compensation value. During normal operation, the deterministic latency controller may sum together the worst-case latency value and the predetermined link reinitialization latency compensation value to obtain a total compensated deterministic latency that is applied to all data links for simultaneous data release.

Methods and apparatus for providing deterministic latency for communications interfaces

The present application is directed to an electronic device that has a receiver configured to receive data from a second electronic device and identify potential sync header locations within a portion of the data by performing a mutually exclusive or (XOR) logic operation on a plurality of sequential pairs of bits of the data. Additionally, the receiver is configured to identify sync headers in the data by determining which of the potential sync header locations is shared in subsequent portions of the data.
