ALTGX Setting
Use this option in Automatic Synchronization State
Machine mode to indicate the number of continuous
valid code groups that it must receive between
erroneous code groups to reduce the error count by
one. The rx_syncstatus stays high as long as the
error count is less than the programmed error count.
Use this option in Automatic Synchronization State
Machine mode to indicate the number of erroneous
code groups (error count) that it must receive to lose
synchronization. The loss-of-synch is indicated by the
rx_syncstatus signal going low.
Use this option in Automatic Synchronization State
Machine mode to indicate the number of word
alignment patterns that it must receive without
intermediate erroneous code groups to achieve
synchronization. The rx_syncstatus signal is driven
high to indicate that synchronization has been
achieved.
This option sets the word alignment pattern length.
The available choices depend on the following
conditions:
■
■
■
Enter the word alignment pattern in MSB to LSB order
with MSB at the left most bit position. The length of
the alignment pattern is based on the What is the
word alignment pattern length? option. The word
aligner restores the word boundary by looking for the
pattern that you enter here. For example, if you want to
set the word alignment pattern to /K28.5/:

You must enter the word alignment pattern
length: 10.
You must enter the word alignment pattern:
0101111100 (17C).
