Use Mode
To use OOB, the following RX termination conditions need to be applied:
• AC-coupled case: Termination voltage should be 800 mV or greater
• DC-coupled case: Termination voltage should be 900 mV or greater
Table 4-7: RX OOB Signaling Attributes
Attribute Type Description
RXOOB_CFG 7-bit Binary OOB block configuration.
RXOOB_CLK_CFG String Selects which clock to use for OOB.
SATA_BURST_VAL 3-bit Binary Number of bursts to declare a COM match for
SAS/SATA.
SATA_EIDLE_VAL 3-bit Binary Number of idles to declare a COM match for
SAS/SATA.
SAS_MIN_COM Integer 1-63. Lower bound on activity burst for COM FSM for
SAS/SATA.
SATA_MIN_INIT Integer 1-63. Lower bound on idle count during COMSAS for
SAS.
SATA_MIN_WAKE Integer 1-63. Lower bound on idle count during
COMINIT/COMRESET for SAS/SATA.
SATA_MAX_BURST Integer 1-63. Upper bound on activity burst for COM FSM for
SAS/SATA.
SAS_MAX_COM Integer 1-127. Upper bound on idle count during COMSAS
for SAS.
SATA_MAX_INIT Integer 1-63. Upper bound on idle count during
COMINIT/COMRESET for SAS/SATA.
SATA_MAX_WAKE Integer 1-63. Upper bound on idle count during COMWAKE
for SAS/SATA.
PCS_RSVD_ATTR[8] 1-bit Binary OOB power up. The OOB circuit can be optionally
powered down when not being used.
1'b0 = Circuit powered down.
1'b1 = Circuit powered up (PCIe, SATA/SAS,
protocols/applications using OOB).
