SATA2 and SATA3 Controller Interfaces
The SoC has up to four SATA2 ports and two SATA3 ports depending on product SKU. 
Each port consists of a Transmitter differential pair and a Receiver differential pair 
which are in the 1.0-Volt Core power well of the SoC.
• SATA_TXP[3:0], SATA_TXN[3:0] (Low Voltage Differential)
• SATA_RXP[3:0], SATA_RXN[3:0] (Low Voltage Differential)
• SATA3_TXP[1:0], SATA3_TXN[1:0] (Low Voltage Differential)
• SATA3_RXP[1:0], SATA3_RXN[1:0] (Low Voltage Differential)
For Serial ATA (SATA) interface electrical specifications, refer to Tables 29–34 in Section 
7.2 of the Serial ATA Revision 3.0 Specification. The SoC as a SATA Host supports 
Gen1i, Gen1m, Gen2i, Gen 2m, and Gen3i as defined in the specification. The SoC 
supports Gen1m and Gen2m External SATA (eSATA) on the SATA2 Controller only.
Nominal channel speeds are 1.5 (Gen1) and 3.0 (Gen2) Gbps for the SATA2 and SATA3 
controllers. The SATA3 controller also supports 6.0 Gbps.
The SoC electrical requirements for the SATA2 and SATA3 differential reference clock 
Other SATA Controller signals not part of the Serial ATA Revision 3.0 Specification:
• SATA_GP0, SATA3_GP0 (Input)
• SATA_LEDN, SATA3_LEDN (OD Output)
