Signal Name
Brings PCI device registers and logic to a consistent state.
Reference Clock: 100MHz differential pair.
Note: AC coupling required. See “PCI-E and SATA Reference
Clock AC Coupling Recommendations” on page 100.
Analog obvservation point for manufacturing test of internal
voltage regulator.
Note: For normal operation, do not terminate.
Connect a 1.37k Ω ± 1% external calibration resistor between
these two pins.
