PETp(x) PCI Express Transmit Positive signal of (x) pair.
PETn(x) PCI Express Transmit Negative signal of (x) pair.
PERp(x) PCI Express Receive Positive signal of (x) pair.
PERn(x) PCI Express Receive Negative signal of (x) pair.
/- Cable REFerence CLocK: Provides a reference clock from the host system to the remote system.
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
