ABSTRACT:
Apparatus for generating trigger signals for a serial stream of bits which has continuously repeating patterns and which has been formed by serializing a plurality of parallel streams, for example, a maximal length PRBS. The apparatus operates by identifying with which parallel stream cycle a trigger signal should occur and with which bit of the parallel stream in that cycle the trigger signal should be associated. Embodiments constructed in accordance with the invention can operate mainly at the clock rate of the parallel streams, that is, the lower clock rate.
