USB 3.0 Technology Overview
Introduction: USB 3.0, that is, “Universal Serial Bus 3.0”, as the latest version of the USB interface Q technology, not only provides a significant increase in data transfer speeds, but also enhances the power management capabilities and bi-directional data transfer mechanism. It was released to accommodate the growing demand for high-speed data exchange and device power supply.
1.USB 3.0 Technology Overview
USB 3.0, also known as SuperSpeed USB, is a computer bus standard developed by the USB Implementers Forum (USB-IF) to provide higher data transfer speeds than earlier USB versions. This technology was introduced in 2008 with the goal of optimizing performance when connecting USB devices to computers, supporting high-speed data transferQ and enhanced power management.The introduction of USB 3.0 has not only improved the productivity of individual users, but also revolutionized the way professional designers and IT industry practitioners make it easy to move large amounts of data quickly.
USB 3.0 introduces a new physical layer protocol that allows it to operate from the same 5V power supply as USB 2.0, but with speeds boosted to as much as 5 Gbits, which is more than a 10-fold increase in bandwidth over USB 2.0's 480Mbis. To achieve this speed increase, USB 3.0 uses a new transmission mechanism that minimizes packet loss while supporting both asynchronous and synchronous data transfers.
