8.1.2 Terminating Unused SATA Signals
If the SATA port(s) will not be implemented on the platform, SATAx_RX[P/N] and
SATAx_TX[P/N] signals may be left unconnected (where ‘x’ is the port number left as no
connect).
If the Serial ATA interface will not be implemented on the platform at all, designers must
take the following actions:
• Tie the following signals to ground:
o SATA[1:0]_RX[P/N], SATA_RBIAS, SATA_CLK[P/N]
• The following signals can be left as no connects:
o SATA[1:0]_TX[P/N]
• VCCA1P05_SATA should be connected directly to VCC1.05, but the filter capacitors are
not required.
8.1.3 SATA Test Note
Due to changes provided by the latest Serial ATA Interoperability Program Revision 1.4
Unified Test Document Version 1.00, the following testing specs are now obsolete:
• TSG-05 (Rise/Fall Imbalance)
• TSG-06 (Amplitude Imbalance)
• TSG-07 (Gen1 -1.5Gb/s TJ at Connector, Clock to Data fbaud/10)
• TSG-08 (Gen1-1.5Gb/s DJ at Connector, Clock to Data fbaud/10)
