Receive Repetitive Pattern Synchronization
Repetitive pattern synchronization synchronizes the receive pattern generator to the incoming repetitive pattern.
The receive pattern generator is synchronized by searching each incoming data stream bit position for the
repetitive pattern, and then checking the next 32 data stream bits. Synchronization is achieved if all 32 bits match
the incoming pattern. If at least six incoming bits in the current 64-bit window do not match the receive PRBS
pattern generator, automatic pattern re-synchronization is initiated. Automatic pattern re-synchronization can be
disabled.
See Figure 5-14 for the repetitive pattern synchronization state diagram.

Receive Pattern Monitoring
Receive pattern monitoring monitors the incoming data stream for both an OOS condition and bit errors and counts
the incoming bits. An Out Of Synchronization (OOS) condition is declared when the synchronization state machine
is not in the “Sync” state. An OOS condition is terminated when the synchronization state machine is in the “Sync”
state.
Bit errors are determined by comparing the incoming data stream bit to the receive pattern generator output. If they
do not match, a bit error is declared, and the bit error and bit counts are incremented. If they match, only the bit
count is incremented. The bit count and bit error count are not incremented when an OOS condition exists.
