iPhone to jump to Broadcom chips?

updated 07:55 am EST, Wed January 7, 2009

iPhone May Use Broadcom

Apple may be turning to Broadcom for the cellular hardware in future iPhone models, say Taiwan-area manufacturers allegedly aware of the changes. Although the company currently uses Infineon chips for the phone's core functions, the insiders claim to have seen circuit boards for either revised or future iPhones with unnamed Broadcom parts for the cellular baseband and RF functions. The swap could suggest a partial or complete replacement of Infineon for the next wave of Apple's devices.

What reasons or features Broadcom would bring to the handset are currently unknown. At present, the only modern and publicly disclosed 3G baseband chip from the company is the BCM2153, which is limited to 7.2Mbps HSDPA and lacks HSUPA or other more advanced technologies that are due to arrive with Infineon's X-GOLD 618 this year. Broadcom hasn't announced any updates to its own chipsets since.

Any switch would represent an upheaval in the cellular industry, where Infineon has become increasingly dependent on its iPhone contracts for a significant part of its cellphone revenue. A flip to Broadcom may hurt Infineon's business to the point where it may exit cellphone chips but is potentially an assist to the new contractor, which itself has had little recent success in getting large contracts.

    Keeping options open..

    I wouldn't be surprised if Apple is keeping it's options open in terms of suppliers. Apple could simply be putting Broadcom chipsets through their paces in case Infineon's technology stalls. Jobs has stated publicly before that he likes having flexibility.

    this goes along with

    the rumors that Apple may be making iPhone Chips internally after it bought into 2 Semi Conductor developers.

    weak sauce

    Unless Broadcom steps up with at least Class 8 HSDPA, they are worthless.

    Broadcom as a

    bargaining chip to keep Infineon costs down. Apple likely keeping it's options open so Infineon doesn't get cocky. If I recall correctly, there were rumors of the the Infineon chip having some problems, so maybe Apple just doesn't want to take any chances if future Infineon chips have any issues.
