XAUI Link Synchronization Function
For each lane, the receive section of the XAUI link state machine incorporates a synchronization state machine
that monitors the status of the 10-bit alignment. A 10-bit alignment is done in the SERDES based on a comma
character such as K28.5. A comma (0011111 or its complement 1100000) is a unique pattern in the 10-bit space
that cannot appear across the boundary between any two valid 10-bit code-groups. This property makes the
comma useful for delimiting code-groups in a serial stream.This mechanism incorporates a hysteresis to prevent
false synchronization and loss of synchronization due to infrequent bit errors. For each lane, the sync_complete
signal is disabled until the lane achieves synchronization. The synchronization state diagram is shown in Figure 1.
Table 1 and Table 2 describe the state variables used in Figure 1.

Functions
Variable
sync_status
Description
FAIL: Lane is not synchronized (correct 10-bit alignment has not been estab-
lished).
OK: Lane is synchronized.
OK_NOC: Lane is synchronized but a comma character has not been detected
in the past TBD seconds.
TRUE: Align subsequent 10-bit words to the boundary indicated by the next
received comma.
FALSE: Maintain current 10-bit alignment.
Current number of consecutive cg_good indications.

Function
sync_complete
Description
Indication that alignment code-group alignment has been established at the
boundary indicated by the most recently received comma.
Indication that a valid code-group, with correct running disparity, containing a
comma has been received.
Indication that a valid code-group with the correct running disparity has been
received.
Indication that an invalid code-group has been received.
Indication that comma timer has expired. The timer is initialized upon receipt of a
comma.
