      That makes sense - it is either that - or throw a lot of product away  and make every one pay for the culled top performers.  We did that often with our complex ICs way back when I was a worker bee.

      Summary info received from Engineering at SiLabs:

      Production tells me that speed grading was implemented on or about 27MAR08. (don't know the delay, if any, to the laser date code printed at the end of the process ....K5BCQ comment) 

      Speed grading is implemented by disabling the output for certain configurations.  Users may find configurations that operate above published frequency.  However, while a part may support higher than graded frequencies, it may not meet other specs such as temperature operating range, DCO range etc.
