Stratix IV Device Handbook Volume 2: Transceivers
In some Basic double-width configurations with 16-bit PMA-PCS interface, you can
configure the word aligner in bit-slip mode by selecting the Use manual bit slipping
mode option in the ALTGX MegaWizard Plug-In Manager.
The word aligner operation for Basic double-width with 16-bit PMA-PCS interface is
similar to the word aligner operation in Basic single-width mode with 8-bit PMA-PCS
interface. For word aligner operation in bit-slip mode, refer to
Single-Width Mode with 8-Bit PMA-PCS Interface Modes” on page
difference is that the bit-slip word aligner in 16-bit PMA-PCS interface modes allows
8-bit and 16-bit word alignment patterns, whereas the bit-slip word aligner in 8-bit
PMA-PCS interface modes allows only a 16-bit word alignment pattern.
A 20-bit PMA-PCS interface is supported only in Basic double-width mode.

Table 1–30. Word Aligner in 20-Bit PMA-PCS Interface Modes
The word aligner operation in Basic double-width mode with 20-bit PMA-PCS
interface is similar to the word aligner operation in Basic double-width mode with a
16-bit PMA-PCS interface. For word aligner operation in manual alignment mode,
refer to
Modes” on page
aligner in 20-bit PMA-PCS interface modes allows 7-, 10-, and 20-bit word alignment
patterns, whereas the manual alignment mode word aligner in 16-bit PMA-PCS
interface modes allows only 8-, 16-, and 32-bit word alignment patterns.
In some Basic single-width configurations with 20-bit PMA-PCS interface, you can
configure the word aligner in bit-slip mode by selecting the Use manual bit slipping
mode option in the ALTGX MegaWizard Plug-In Manager.
The word aligner operation for Basic double-width with 20-bit PMA-PCS interface is
similar to the word aligner operation in Basic single-width mode with an 8-bit
PMA-PCS interface. For word aligner operation in bit-slip mode, refer to
Aligner in Single-Width Mode with 8-Bit PMA-PCS Interface Modes” on page
The difference is that the bit-slip word aligner in 20-bit PMA-PCS interface modes
allows only 7-, 10-, and 20-bit word alignment patterns, whereas the bit-slip word
aligner in 8-bit PMA-PCS interface modes allows only a 16-bit word alignment
pattern.
