Cyber-sleuthing can be both fun and profitable.
When Cirrus Logic
Production problems for a new chip design in March didn't make sense if the target device were an iPad 2 already on its way to your neighborhood Apple store. And it was a bit early to produce audio chips for an iPhone 5 not slated for release until mid to late summer.
But I forgot about another major Apple product line with a regular update schedule: the iMac.
When iFixit ripped a new iMac apart last Wednesday, it found a powerful quad-core Intel
That's all very good, investable information given that Apple still ships about 1.2 million desktops, including the iMac line, per quarter. But that's not what I came to iFixit for this time.
Then there was the audio chip -- a Cirrus Logic 4206BCNZ. Stop the presses! This is very likely to be the chip that caused Cirrus to stumble.
The 4206 line of audio chips is an Apple-specific version of the 4207 chip that Cirrus sells to anybody. Cirrus doesn't generally promote or sell the 4206, but an earlier version showed up in the recently refreshed line of Apple MacBooks and the Mac mini from the summer of 2010. That one was called 4206ACNZ. The lineage is clear, and about eight weeks of lead time from March matches up nicely with the iMac.
If nothing else, this episode highlights just how tightly Cirrus Logic has tied its fortunes to Apple -- and how far backward it will bend over to keep Cupertino happy.
So there you have it: Don't hold your breath waiting for an amazingly high-volume gadget from Motorola Mobility
