Signal Descriptions
One Stop Systems OSS-PCIe-HIB25-x4-H/T
Rev. A
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.
