iFixit studied Thunderbolt
Our colleagues from the Ars Technica resource among others became interested in new RAID systems from the Promise company. And here that them surprised, so it is need докупать a firm cable of Thunderbolt from Apple. «Why it is impossible to use Mini DisplayPort cable?» — they asked technical support of Promise. «Because the "clever" cable is necessary — the specialist — a cable which will have the insertion» answered. The puzzled founders of Ars Technica very much would like to glance in a cable for $49, but all of them did not decide. But their friends — our old acquaintances from iFixit — in a trice ran in near Apple Store behind "victim". Inside the most interesting was found much.
We precisely knew, where it is necessary to find. The strong plastic which has been put on a cable from both parties, looked very suspiciously. The warm knife of Exacto perfectly coped with this plastic. After an accurate cut and a raspayka we managed to remove the case from a konnektor.
When the case was removed, we made powerful volume of work, cutting and raspaivy metal round the socket with a view of to remove it. Having removed metal, we found under it the hardware.
We found two Gennum GN2033 chips, on one from each party. Nearby — other chips, even less, which, surely, increase cable cost: two chips c S6A 1JG labels on one party, and two more — with markings 1102F SS8370 and 131 3S — on another. Round them, certainly, there are a lot of small resistors (they provide necessary resistance).
We presented that other end of a cable will be same, and appeared are right. The 50-dollar cable of Apple contains 12 marked chips in the general difficulty and unlimited quantity less huge electronic a component.
Here to you and the answer to a question why the cable costs $49. Directly pair of chips of Gennum provides so impressing speed. Oh, wound Apple and Intel with this Thunderbolt, and in appearance after all and you will not tell. [ifixit]
