/-  

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
