LOS_COUNT[4:0]
The Loss of Signal 1’s/0’s transition detector count field sets the value for the number of
consecutive all-zeros or all-ones pattern that will force the CRU out of the LOCK TO DATA
state. Each bit in the binary count represents sixteen ones or zeros in the pattern. (i.e.
LOS_COUNT has an accuracy of ±15). For example, to set the consecutive all-ones or all-
zeros pattern to 128 the LOS_COUNT should be set to “01000”b. The default value for this
field is 128.
