USB 3.0 Training by TONEX, USB 3.2 Updates
The third generation of USB increases transfer rates to 5.0Gbits/s (SuperSpeed) and is backward compatible with all earlier USB 1.1/2.0 Low-Speed, Full-Speed, and High-Speed peripherals and hubs.
USB 3.2 doubles the maximum speed of a USB connection to 20Gb/s. A USB 3.0 connection runs at 5Gb/s, and slower connections were USB 2 or even USB 1.1.
USB 3.2 5Gb/s devices are now called “USB 3.2 Gen 1.” 10Gb/s USB devices will become “USB 3.2 Gen 2.” And all 20Gb/s devices will be “USB 3.2 Gen 2×2.”
USB 3.2 means 5, 10, or 20Gbps.
USB 32 doubles the maximum speed of a USB connection to 20Gb/s. A USB 3.0 connection tuns at 5Gb/s, and slower connections were USB 2 or even USB 1.1. The new 3.2 version 5Gb/s data rate was branded “SuperSpeed USB,” following USB 2’s 480Mb/s “High Speed” and USB 1.1’s 12Mb/s “Full Speed.”
5Gb/s devices are now called “USB 3.2 Gen 1.” 10Gb/s devices become “USB 3.2 Gen 2.” And 20Gb/s devices will be “USB 3.2 Gen 2×2.”
SuperSpeed USB brings significant performance enhancements to the USB standard. It will deliver 10x the data transfer rate of Hi-Speed USB, as well as improved power efficiency.
- SuperSpeed USB 3.0 has a 5 Gbps signaling rate offering 10x performance increase over Hi-Speed USB.
- SuperSpeed USB 3.0 is a Sync-N-Go technology that minimizes user wait-time.
- SuperSpeed USB will provide Optimized Power Efficiency.No device polling and lower active and idle power requirements.
- SuperSpeed USB 3.0 is backwards compatible with USB 2.0. Devices interoperate with USB 2.0 platforms. Hosts support USB 2.0 legacy devices.
- SuperSpeed USB 3.0 significant enhancements in the areas of device and system power conservation, error handling, and data flow control.
- SuperSpeed USB 3.0 bus instances replace the USB broadcast bus model with directed (unicast) packets
- Dual-simplex signaling enables asynchronous device notifications and simplifies link partner communication used in link flow control, packet acknowledgement and retry, and power management transitions.
- USB 3.2 Gen 1: originally known as USB 3.0, and previously renamed to USB 3.1 Gen 1. It’s the original USB 3.0 specification, and it can transfer data at up to 5Gbps.
- USB 3.2 Gen 2: Previously known as USB 3.1, and then later as USB 3.1 Gen 2. It offers speeds at up to 10Gbps.
- USB 3.2 Gen 2×2: formally known as USB 3.2, it’s the newest and fastest spec, promising speeds at up to 20Gbps (by using two lanes of 10Gbps at once).
