Abstract
A Serial ATA communications system has a host, a device, and a Serial ATA communications cable that connects the host to the device. The Serial ATA communications cable includes (i) a pair of transmit lines configured to carry a differential mode transmit signal, (ii) a pair of receive lines configured to carry a differential mode receive signal, and (iii) a set of ground lines. The host includes a transmit circuit configured to connect to the pair of transmit lines of the Serial ATA communications cable, a receive circuit configured to connect to the pair of receive lines of the Serial ATA communications cable, and a sensor. The sensor is configured to provide an output signal indicating whether a Serial ATA device is connected to the Serial ATA communications cable in response to a test signal applied to the set of ground lines.
