CES USB 3.0, the upcoming version ofthe universal add-on standard re-engineered for the HD era, made asmall appearance at the Consumer Electronics Show (CES). It wasn'tdemonstrated in operation, but we did get to see what the newconnectors look like.
Not, alas, the optical one, we have to report, but the electricalconnectors. On show in public for – we believe – the first time, we gotto see the new full-size connector, the socket it slips into and thenew mini-socket. You can see the optical port here.
The USB 3 connector...
...and in close-up...
...and in diagrammatic detail
Here's the socket:
The standard USB 3 socket...
...which you can see more clearly in this diagram
And, finally, the mini-socket:
Dubbed SuperSpeed USB, the third major incarnation of the serial busstandard is set to deliver data transfer speeds of around 4.7Gb/s - tentimes today's 480Mb/s limit.
The new spec will be compatible with older USB 1.1 and 2.0 products,cables and connectors, and you can see from the diagram of the standardconnector how that's achieved: the extra pins are placed behind the USB1.1/2.0 ones. USB 3.0 connectors and receptacles will be deeper thanthe current ones.
An initial USB 3.0 spec is due to be reviewed later this month. Thefull USB 3.0 specification is expected to be completed by the end ofJune 2008.
