Note 5:

The Minimum and Maximum Limits are based on statistical analysis of the device performance over process, voltage, and temperature ranges. This

parameter is functionality tested only on Automatic Test Equipment (ATE).

Note 6:

Care must be taken to ensure TSTC and THTC are met so input data are sampling correctly. This SSCG parameter only shows the performance of tracking

Spread Spectrum Clock applied to TxCLK IN pin, and reflects the result on TxCLKOUT+ and TxCLKOUT− pins.
