/- Cable Reference Clock: Provides a reference clock from the host systems to the remote systems
SB_RTN Side Band ReTurn: return path for single ended signals from remote systems
CPRSNT# Cable PreSent: Indicates the presence of a device beyond the cable
PWR PoWer: Provides local power for in-cable redriver circuits. Only needed on long cables. Power does not go across the cable
PWR_RTN PoWer ReTurn: Provides local power return path for PWR pins.
CWAKE# Cable Wake
CPERST# Cable PCI Express Reset
