Electrical Characteristics

4.12.17.1.1 SATA PHY Transmitter Characteristics

Table 77 provides specifications for SATA PHY transmitter characteristics.

4.12.17.1.2 SATA PHY Receiver Characteristics

Table 78 provides specifications for SATA PHY receiver characteristics.

4.12.17.2 SATA_REXT Reference Resistor Connection

The impedance calibration process requires connection of reference resistor 191

Ω. 1% precision resistor

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.
