TX Only Sample Video PHY Controller Log - 2.2 English

The following log entries were taken from a GTXE2 Video PHY Controller using CPLL to clock the TX. The first log shows a typical flow for a video format change while the second one shows a log that attempted to retry the TX alignment.

TX Alignment retry is only applicable for GTXE2 devices and can occur more than once in a single format change. TX Alignment retry is attempted when the watchdog timer for TX alignment times out after the TX Reset Done state is attained.
