My experience with Digikey was a bit doubtful with respect to the "freshness" of
their stock. The first delivery of a few XC3S1600 in late 2006 was OK, so I built
my first prototypes, they worked perfect. The chips in the second delivery in
early 2007 had huge problems with the DCM. Either it didn't work at all or a
phase shift step killed it.

It took a while until I discovered that they had sent me A0-revisions. In A0 the
DCM is (IMO) quite useless as the maximum input and output frequency is only
90MHz... No wonder my 132MHz DDR-stuff didn't work...
