6.8 eSATA

A switch is used to direct the SATA signals to the onboard eSATA connector or to the expansion header, where they are routed to the mSATA connector on the LCD Module. If the signal on the expansion header, P19-4, is left open, the signals go to the eSATA onboard connector. If the pin is grounded via the SATA_SEL jumper (J1) on the LCD Module, the switch is activated and the signals are routed to the expansion headers.

The eSATA interface on the Processor Module is a combination of two separate interfaces, SATA and USB. The eSATA port can be used as an eSATA or a USB 2.0 port. The USB signals originate from the USB 3.0 HUB. The SATA interfaces originate from the AM57xx processor via the switch.

Power for the eSATA is from the USB power pins, 5V. Power is routed to the eSATA connector via the TPS2560 FET switch. It is capable of providing the 500mA required by the eSATA connector. Only 5V is supplied.

Note:

When J1 on the LCD Module is installed (for mSATA), the eSATA on the Processor Module will no longer function. However, the connector can still function as a USB 2.0 port.
