I'm sure it's not as dramatic as all that. The article that was posted on today's EE Times talked about a production test that was inadequate in catching all failures on some spec parameter. After the test was made more rigorous, yields fell. Why should end customers care what the ppm reject rate is on finished units at the factory? As long as the price of the iPad stays the same, the manufacturing yields and gross margins are problems for Apple and Cirrus, not for the end customer.

It's clear that they don't want to specifically point at the issue because every iPad2 owner and their mother will want a replacement... As it is, they're flying it under the radar...

Doubtful. If you try to look up the CL part number for the part listed in the iPad2 teardown analysis, you can't find a data sheet or any info about it anywhere. This leads me to believe it was a custom part made specifically for Apple. For Wolfson or anyone else to start a new design to Apple's specs and get it into production would be quite a long process. Besdies, Apple designed out Wolfson several generations ago. Hard to imagine them going back in that direction now.

Is that going to affect Apple supply chain? What is the inventory for Apple?

Getting new products mature enough to have a consistant good yield takes time. If it is in a new process, it could take many months.

I think there is nothing much to be worried from apple's counterpart as it does not mention any technical deficiency of the codec.

Cirrus makes some excellent audio CODECs. It's a shame to hear they are getting bitten by yield issues on the new part...presumably the one in the iPad2.

Will apple phones and iPad be on a shortage? Perhaps this will actually benefit Apple as the scarcity principle might become a good hook to drive public appreciation of the "gizmos". Looks like this device is a new chip. Isn't using a new chip a little risky? Is apple becoming an early adopter? Well, I guess this is the only way to hit the market with the final frontier of technology. Some are innovators and some like to play it safe. Sometimes you have to make a trade-off don't you think?
