The USB interface is upgraded from 2.0 to 3.0. Because the USB3.0 interface is very different from the USB2.0 interface specification, what changes does USB3.0 bring? What are the different features of Xuanzhan HD USB3.0 interface board? Let’s first look at the difference between the two.
The USB3.0 interface adds two pairs of differential signal lines for data transmission, which can realize bidirectional data transmission —- full-duplex bidirectional high-speed serial data transmission and support asynchronous transmission mode. And the specification provides faster transfer speeds and higher energy efficiency than USB 2.0, which is widely used in PC peripherals and consumer electronics.
1.1. Color USB2.0 is usually white or black, while USB3.0 is adjusted to blue interface.
1.2. In terms of USB socket pins, USB2.0 adopts 4-pin design, while USB3.0 adopts 9-pin design, which is more powerful than USB3.0.
1.3. Appearance of USB ports USB3.0 interfaces will be marked with the “SS” style, while USB2.0 only marks the common USB logo.
USB3.0 is characterized by very fast transmission rates, theoretically up to 5.0Gbps, 10 times faster than the current High Speed USB of 480Mbps (USB 2.0 for short).
Almost all new USB3.0 products are downward compatible with USB2.0 ports. Therefore, upgrading to a new USB3.0 camera or capture device does not require a USB3.0 capable computer. That said, you can’t take the speed advantage of USB3.0 without a USB2.0 port.
4. Add functions
USB2.0 is only half-duplex, which means it can only send communication in one direction at a time. USB3.0 is full-duplex, which means it can send signals in both directions.
5. Low power consumption
USB3.0 has low power performance, about 25% lower power consumption than USB2.0 at 20MB/s data transfer volume. In addition, USB3.0 is more energy efficient than USB2.0 and can use power saving mode for devices that are temporarily in the waiting state.
Xuanzhantechnology USB3.0 interface board is specially developed and designed for SONY FCB HD camera module. It is connected to the coding board through LVDS interface and supports the output of 1080P60 HD video signal.
USB3.0 interface board supports various functions such as direct control of camera zoom through USB serial port, and is widely used by SONY camera development engineers. And support a set of external serial ports, convenient for various control boards to control the camera. Widely used in medical equipment and image detection equipment and other fields.
Connect the movement through LVDS interface, automatically identify the HD video format of the movement. Support 720P, 1080I, 1080P frame rate, so that the SONY FCB integrated camera movement shot images immediately displayed on the computer screen.
