SuperSpeed Signaling over USB-C

All USB SuperSpeed signals are transmitted and received over the same differential pairs (TX1, RX1, TX2 and RX2). SuperSpeed signaling over USB-C can use either the TX1/RX1 pair or the TX2/RX2 pair; this is also known as an x1 implementation. USB over USB-C adds the ability to enable the unused TX/RX pair from the x1 implementation to effectively double the data throughput without increasing the data rate, which is known as an x2 implementation.

Table 8 shows the different USB 3.0 and USB 4.0 specification versions and associated data rates.
