    Hi Tony,
    SATA termination calibration to 100 Ohms differential is performed as part of final test. There is no user control of this value.

    As PCB layout can have a significant impact on the channel impedance, please have the customer review SPRAAR7 looking for deviations from the layout recommendations contained therein.
