Lightning connector and USB3.0

Several have voiced disappointment that Apple didn't have foresight for USB3.0. I didn't have time to respond and can't find thread, Im not saying this is what they did, just that its plausible.

dual sided 8pin lightning (technically 16) example pinout 1

Code:

1---2---3---4---5---6---7---8---
Gnd tx1 rx1 5v. 5v. rx2 tx2 gnd

Gnd tx3 rx3 5v. 5v. Rx4 tx4 gnd
16--15--14--13--12--11--10--9---

Reversible, 8 digital signal lines, 4 sets of differential pairs like USB3.0. Obviously it would still require new cables with usb3.0 compliant A connectors.

 

Thats not exact because I don't know, just one plausible example of many.

There are several variants of that pinout which would get the job done. Also the controller inside the iPhone would have to support USB3.0, which is probably not the case.

My point is they could upgrade for it in future iPhone 5S/6 etc without changing lightning connector.

 

Correct, not denying that, that and cost is why they didn't do it now... Im saying down the road, its plausible they could upgrade. It would take roughly 3 things: updated iPhone flash memory, updated iPhone Lightning connector transceivers, and an updated cord with a USB3 compliant USB A connector.

But the new Lightning connector and dock themselves would not have to change.
And these iPhone5 Lightning to USB2 cables would still work at non-superspeed.

Get ready to buy some superspeed Lightning to USB3.0 cables in the next 1-3 years ;-)

 

It has to support more than 8pins, it has to be a 16pin connector.

Proof is in the keynote. "All digital, 8-signal design"

If all 8pins are digital signals, and the shell is reference frame ground, that would work for data, but you couldn't charge the phone. Where is the 5V line? Not feasible.

See my original post for one example of how an 8 digital signal, 4 pair of differential signal design might work.

 

That's good info. Wasn't available when discussed before. Pin4/8 ID lines are a good discovery.

Granted, this all ONLY deals with the authentication chip as it operates now.

My theory for future enhancement for USB3, lies on GUESSWORK. That they would change the female phone connector, to a 16pin design.

The cable would be different. The Lightning side would be physically the same, though the authentication chip would be updated to handle all 16 pins independently. And the USB host side, would be updated for a blue USB3 connector.

This wouldn't have to effect backwards compatibility.

Then the 'new' authentication chip would assign 8 signal pins, 4 sets of differential pairs.

Maybe this will happen next year with iPhone 6? *shrug*.

In this perfect world (which we don't know is even possible, just theoretically). Old lightning cables would still work, just at USB2 speed. And the new cables would work on old phones, just at USB2 speed.
