Figure 15-2. Minimum Receiver Eye Timing and Voltage Compliance Specification
15.5.1
Compliance Test and Measurement Load
The AC timing and voltage parameters must be verified at the measurement point, as specified within
0.2 inches of the package pins, into a test/measurement load shown in Figure 15-3.
Note:
The allowance of the measurement point to be within 0.2 inches of the package pins is meant to acknowl-
edge that package/board routing may benefit from D+ and D– not being exactly matched in length at the
package pin boundary.

16. Serial RapidIO
This section describes the DC and AC electrical specifications for the RapidIO interface of the PC8641,
for the LP-Serial physical layer. The electrical specifications cover both single and multiple-lane links.
Two transmitters (short run and long run) and a single receiver are specified for each of three baud rates,
1.25, 2.50, and 3.125 GBaud.
Two transmitter specifications allow for solutions ranging from simple board-to-board interconnect to
driving two connectors across a backplane. A single receiver specification is given that will accept sig-
nals from both the short run and long run transmitter specifications.
The short run transmitter should be used mainly for chip-to-chip connections on either the same printed
circuit board or across a single connector. This covers the case where connections are made to a mez-
zanine (daughter) card. The minimum swings of the short run specification reduce the overall power
used by the transceivers.
