The following functions have been implemented to facilitate a high-speed and reliable  
synchronization (see figures 28).  
– Interference Rejection  
In the case where two or more edges appear in the data stream within a time period of 16  
reference clocks, these are detected as interference without performing additional  
adjustments.

– Phase Adjustment  
In the case where an edge with a phase angle of 20 to 112 degrees appears in the data stream  
within the time window, the phase will be adjusted by 1/16 of the data clock.
