4.7.13.3 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.
4.7.13.4 SATA Connectivity When Not in Use
When both SATA and thermal sensor are not required, connect VP and VPH supplies to ground. The rest
of the ports, both inputs and outputs (SATA_REFCLKM, SATA_REFCLKP, SATA_REXT, SATA_RXM,
SATA_RXP, SATA_TXM) can be left floating. It is not recommended to turn off the VPH while the VP is
active.
When SATA is not in use but thermal sensor is still required, both VP and VPH supplies must be powered
on according to their nominal voltage levels. The reference clock input frequency must fall within the
specified range of 25 MHz to 156.25 MHz. SATA_REXT does not need to be connected, as the
termination impedance is not of consequence.

SATA PHY Receiver Characteristics
The Temperature Sensor is part of the SATA module. If SATA IP is disabled,
the Temperature Sensor will not work as well. Temperature Sensor
functionality is important in supporting high performance applications
without overheating the device (at high ambient temp).
