USB 3.1 Gen 1 vs. Gen 2

August 9, 2018 at 8:00 AM

 

Not sure of the difference between USB 3.1 Gen 1 (aka SuperSpeed USB) and USB 3.1. Gen 2 (aka SuperSpeed USB 10 Gbps or SuperSpeed+)? Don’t worry, you’re not alone. USB has rebranded and restructured how it differentiates between the two, leaving many scratching their heads as to which is which. Have no fear though, we’ve got it all figured out and are here to clear it up for you.

 

If you were impressed by the super speeds brought to you courtesy of USB 3.1, then you’re going to be over the moon for USB 3.1 Gen 2. This iteration of USB technology bolsters speeds and delivers additional benefits sure to please all users. As its name suggests, SuperSpeed+ USB increases the data transfer rate from 5 Gbps to 10 Gbps, making it twice as fast as USB 3.1 Gen 1 and on par with first generation Thunderbolt technology. USB 3.1 Gen 2 also uses more efficient data encoding, which not only increases throughput, but also improves I/O power efficiency.

 

Though the maximum cable length is shortened from 5 meters to 1 meter, USB 3.1 Gen 2 maintains the capability of data plus power over one cable and it can support multiple cameras and the USB3 Vision standard. Plus, USB 3.1 Gen 2 increases the power delivery level from 4.5 Watts to an astounding 100 Watts. This standard will also support USB Type-C, USB DisplayPort over Type-C and USB Power Delivery.

 

USB 3.1 Gen 2 is fully backward compatible with existing USB 3.0 software and devices, 5 Gbps hubs and devices as well as USB 2.0 products. In case there’s still some lingering confusion, here’s a handy chart to help compare these two side-by-side.

Engineers’ Choice

October 13, 2016 at 8:00 AM

 

We depend on our engineers for their innovative ideas. We asked them what topic, technology or trend they thought we should feature in this weeks post. Our engineers’ choice: USB Type-C connectors. Here is an inside look at the connectors that got our enigneers’ stamp of approval.

 

We all love using USB. The plug-and-play interface makes it easy to connect and charge our devices. But it can be aggravating to figure out which USB cord goes with which device, and then which end plugs in where. Forutnately, our prayers have been answered and the technology gods have given us Type-C connectors.

 

USB Type-C is a tiny connector that boasts fast speeds, more power handling capabilities and a simpler, sleeker design.

 

The smaller, slimmer USB Type-C is a single connnector that can be used on all devices. Designed to replace both full-sized USB connectors as well as micro-USB connectors, it is tailored to fit mobile devices, yet powerful enough to be used with laptops and tablets. Whether you’re connecting an external peripheral to your laptop or charging your smartphone, Type-C connectors provide one cable small enough and powerful enough to do it all.

 

The Type-C connector has a simple, reversible design that makes using USB easier than ever. Completely reversible plug orientation and cable direction eliminate the guess work and frustration of not knowing which end is up when plugging in your USB devices.

 

Made for SUPERSPEED+ USB 3.1, Type-C connectors boast lightning speeds of up to 10 Gbps. They also support a vareity of different protocols that, with an adapter, allow output of HDMI, VGA, DisplayPort and other types of technologies from a single USB port. Type-C connectors are designed to provide scalable power and performance to adapt to whatever your future needs may be.

 

Type-C connectors are also made to support  USB Power Delivery (PD). Currently, a USB 2.0 connection provides up to 2.5 Watts of power, that’s enough to charge your phone, but not your laptop. With USB PD, the power delivery is increased to up to 100 Watts, and the power is bi-directional so it can be sent or received. That means that as long as the device and cable support USB PD, you can use a Type-C connector to charge devices from one another and possibly eliminate the need for a separate laptop charging cord.

 

Though USB technology is backward compatible, Type-C connectors are not, so we will continue to see devices and cords with both Type-A and Type-C connectors. Type-C connectors have been integrated into an increasing number of devices over the past year, they are now found on Google’s Chromebook Pixel and Apple’s MacBook and in the furture they may even replace Lightning connectors on iPads and iPhones.

USB 3.1 Gen 1 - Fasten your Seat Belts!

July 16, 2015 at 10:00 AM

 

It's a bird! It's a plane! No, it's SuperSpeed USB!

 

Your data transfer rates will soar to heroic speeds with the launch of USB 3.1 Gen 1, also known as SuperSpeed USB, which boasts three main advantages: speed, power delivery and the new Type-C connector.

 

As its name suggests, SuperSpeed USB delivers data transfer rate up to 5 Gbps, That makes it 10x faster than Hi-Speed USB and it provides power of up to 45 Watts. Plus, it minimizes user wait time because it is a Sync-N-Go technology.

 

SuperSpeed USB delivers optimized power efficiency with no device polling and lower active and idle power requirements. It is able to negotiate power, which allows two devices to decipher which one powers the other and the power direction can be changed without switching the physical cable direction. USB 3.1 Gen 1 is also backward compatible with previous versions of USB as far back as USB 2.0.

 

With USB 3.1 Gen 1 supporting USB Type-C, charging becomes easier than ever with the Type-C connector and its simple, reversible design that takes the guess work and frustration out of plugging in your USB devices. The smaller and slimmer Type-C connector will replace both full-sized USB connectors as well as micro-USB connectors, though there will be USB 3.1 Gen 1 cables that are backward compatible with existing USB 3.0 ports.

 

Set to launch in late 2015 or early 2016, USB 3.1 Gen 1 is coming to market as a single-cable solution supporting video, audio, data and power.  With this super-charged USB delivering more speed, more power and a sleeker, fool-proof design, USB is likely to remain the de-facto interface connecting your devices.
