Infineon cellular chipset in iPhone 3G

Thursday, July 10, 2008

iFixit has dissected the iPhone 3G here. It is a well done and well documented dissection that comes a full day early for iPhone geeks in the US. I do not wish to steal the thunder from the ifixit folks. So, while I will let you look up the rest from the iFixit site, I will touch upon one component that is very close to my heart.

I am hopefully not jumping the gun but here is what I read from the photos that iFixit has posted-

While the folks who did the dissection have so far identified the Infineon Smart3i chip, I think the photo of the chipset also indicates the Infineon 608 baseband. The chip with the part number 337s3394 is very likely the PMB8878, or XGOLD 608. This is further corroborated by the 608xx labeling on that chip and also a similar part from the last iPhone that was identified as the S-GOLD2 baseband processor.

This perhaps confirms something that I have been predicting for around a year now. Infineon's chipset is in the 3G iPhone and by extension, InterDigital's 3G protocol stack is also in!

What about Marvell and Broadcom? Do they have their chips in there?

The video codec in the Infineon chip is from ON2 Technologies, the same company chosen by China for the Olympics .
