SATA Interface Connector
The SATA connector on the SSD is divided into a Signal Segment (S1 - S7) and a Power Segment
(P1 - P15). The connector supports the signal and power segments cabled up to 1 meter (39 inches)
and backplane connections. The connector is designed to blind mate, has staggered contacts to
facilitate “hot plugging”, and supports the 3.0 Gb/sec speed.
Signal Segment Pinout Configuration
A SATA signal cable uses a protocol transmitted over a 7-pin cable. Figure 3 identifies the 7-pin
signal segment of the cable. Table 8 lists the signal definitions of the 7-pin segment.
Figure 3.
SATA Signal Segment
The 7-pin signal segment of the SATA connector includes 3 grounds, 2 transmit, and 2 receive pins.
The transmit pins are TxN 5 and TxP 6 and the receive pins are RxP 2 and RxN 3. This pin
configuration is reversed on the host plug: Pins 2 and 3 are the transmit pins and 5 and 6 are the
receive pins.
