Cable, data, 7 wire (SATA)

This is the data transfer cable. It uses four wires for data transfer, the other three are ground cables. The data wires consist out of one receive (RX) and one transmit (TX) pair. The transmit and receive pair both use a differential transfer method similar to the one used in UTP network cabling. A high frequent signal is used to transfer the data over the cable. SATA-1 uses an 1.5GHZ clock signal, SATA-2 uses an 3.0GHz clock signal.
