6.3.3 Resynchronization

If the Deserializer loses lock, it will automatically try to re-establish lock. For example, if the embedded clock edge is not detected one time in succession, the PLL loses lock and the LOCK pin is driven low. The Deserializer then enters the operating mode where it tries to lock to a random data stream. It looks for the embedded clock edge, identifies it, and then proceeds through the locking process.

The logic state of the LOCK signal indicates whether the data on ROUT is valid; when it is high, the data is valid. The system may monitor the LOCK pin to determine whether data on the ROUT is valid.
