• Manufacturer: Freescale Semiconductor, Inc

The compliance of receiver input signals RD[0:15] and RFRAME with their minimum data valid window
(DV) specification shall be determined by generating an eye pattern for each of the data signals and
comparing the eye pattern of each data signal with the RapidIO receive mask shown in
value of X2 used to construct the mask shall be (1 – DV
±600 mV maximum input voltage values are from the DC specification. A signal is compliant with the data
valid window specification if and only if the receive mask can be positioned on the signal’s eye pattern
such that the eye pattern falls entirely within the unshaded portion of the mask.
The eye pattern for a data signal is generated by making a large number of recordings of the signal and
then overlaying the recordings. The number of recordings used to generate the eye shall be large enough
that further increasing the number of recordings used does not cause the resulting eye pattern to change
from one that complies with the RapidIO receive mask to one that does not. Each data signal in the
interface shall be carrying random or pseudo-random data when the recordings are made. If
pseudo-random data is used, the length of the pseudo-random sequence (repeat length) shall be long
