Abstract
A method and circuit for implementing serial link training sequences, and a design structure on which the subject circuit resides are provided. A transmitter device transmits a training sequence (TS) pattern; then the transmitter device transmits random data for a predefined time duration. The steps of transmitting the TS-pattern, then transmitting the random data for the fixed time duration are repeated. A receiver device detecting a plurality of the TS-patterns separated by the predefined time interval of random data, performs receiver initialization steps. The receiver device performs a plurality of receiver initialization steps including, for example, acquiring byte lock, and a link width determination.
