For the sake of discussion let me just add that even if medesigns comments were true of Microsemi, the Microsemi responses on this form have been from long time Time-Nuts who have for years contributed their knowledge to the betterment of the community in the proudest traditions of acadimia. Never have I seen them use the form for financial gain. Sure corporate greed is a problem in todays society but knowing some of the individuals at Microsemi it is clearly not a black and white issue. Further where it may be acceptable in some cases to release a product early and perform some of the final development on the backs of the customers to better serve their needs such as in the case of the fantastic "TimeLab". In a mission critical product like the CSAC a problem like this will cost Microsemi far more then they would profit from a premature release. These manufacturing defects were clearly something they could not anticipate. I for one will be purchasing many more Microsemi products in the future and viewing their performance on TimeLab with full confidence. Please keep the group update on your progress resolving this issue. It will be interesting to see if a single point of failure is found, a smoking gun so to speak; or whether it will be resolved with a number of minor changes during product evolution. In any case I hope the problem is resolved quickly.
