SATA
Serial ATA (or SATA) is a high speed point to point serial interface that connects a host system to a mass
storage device such as rotating hard drive, solid state drive or an optical drive. Data and clock are serialized
onto a single outbound differential pair and a single inbound pair. Data link rates of 1.5, 3.0 and 6.0 Gbps are
defined by the SATA specification. A SATA link is AC coupled, but the coupling capacitors are defined in the
SMARC specification to be on the Module, for both SATA transmit and receive pairs.
The next figure show how to connect SATA SMARC pins to mSATA connector (page 77 of SMARC Design
Guide).
