Hi Magnus, Bob, Thanks much for your kind words.
The failure rate is thankfully so low that we are not greatly alarmed, and Microsemi has been a champ in resolving any failures with/for us when they did show up. We are awaiting the results of the full re-qualify that Microsemi is doing on the CSAC and were going to announce the issue at that time..
