Figure 1–61. Transceiver Configuration in Serial RapidIO Mode
Lane Synchronization
In Serial RapidIO mode, the word aligner is compliant to the SRIO Specification 1.3
and is configured in automatic synchronization state machine mode with the
parameter settings as listed in
Table 1–20. Synchronization State Machine Parameters
Number of valid synchronization (/K28.5/) code groups received to achieve
synchronization
Number of erroneous code groups received to lose synchronization
Number of continuous good code groups received to reduce the error count by
one
Note to
(1) The word aligner supports 10-bit pattern lengths in SRIO mode.
