Electrical Characteristics
4.11.16 SATA PHY Parameters
This section describes SATA PHY electrical specifications.
4.11.16.1 Transmitter and Receiver Characteristics
The SATA PHY meets or exceeds the electrical compliance requirements defined in the SATA
specifications.
The following subsections provide values obtained from a combination of simulations and silicon
characterization.

4.11.16.2 SATA_REXT Reference Resistor Connection
The impedance calibration process requires connection of reference resistor 191 
on SATA_REXT pad to ground.
Resistor calibration consists of learning which state of the internal Resistor Calibration register causes an
internal, digitally trimmed calibration resistor to best match the impedance applied to the SATA_REXT
pin. The calibration register value is then supplied to all Tx and Rx termination resistors.
During the calibration process (for a few tens of microseconds), up to 0.3 mW can be dissipated in the
external SATA_REXT resistor. At other times, no power is dissipated by the SATA_REXT resistor.
