Figure 2–17. Word Aligner in 10-Bit Mode
In the 10-bit mode, the word aligner automatically aligns the user’s
predefined 10-bit alignment pattern. The pattern detector can detect the
full 10-bit pattern or only the lower seven bits of the pattern. The word
aligner and pattern detector detect both the positive and the negative
disparity of the pattern. A user-controlled enable port is available for the
word aligner.
The 10-bit mode is available only for the Custom mode.
