Introduction

TUSB213IRGYR is a dual high-speed USB 2.0 aware three-port physical layer transceiver which provides both low- and full-speed ports, and is designed for PC peripherals requiring both USB 2.0 and USB 1.1 connectivity. It is specifically designed to be built into mobile, battery-powered devices. TUSB213IRGYR is localized on a 12mm x 7mm, 118-pin TQFN (Thin Quad Flat No-Lead) package and is housed in the most optimal package by TI, designed to be the size of a person’s fingertip.

Application field

TUSB213IRGYR has a number of applications, some of which are listed below.

• Mobile phones
• Tablet PCs
• Peripheral cords and cables
• Cameras
• Printers
• Docking In-Vehicle infotainment

Design Principle

The primary purpose of the TUSB213IRGYR is to provide physical, data link and application level communication of all types of data between a host and a USB device, including Audio/Video (AV), Graphics, Imaging, Networking and Storage. It provides products that eliminate the need for customers to invest in multiple USB PHY products and provides a single USB capable connection, allowing customers to develop products that are built for both USB 1.1 and USB 2.0 connectivity.

The TUSB213IRGYR is designed to be pin-compatible with the current generation of USB 2.0 PHYs (including Texas Instruments\' TUSB213IBB and TUSB213 interface ICs), so that customers are able to design new products from the same base IC, with no requirement to spend extra time designing a new board. Furthermore, the TUSB213IRGYR is versatile and can operate in both peripheral and host modes, which is ideal for customers looking to build mobile products.

TUSB213IRGYR also provides a range of digital features that are integrated into the device. These features provide enhanced flexibility and performance, helping customers design and validate their devices quickly and easily. They include features such as hot-plug detection, droop detection, USB 2.0 suspend detection, USB 2.0 device reset, power management and connection speed detect.

Operation Details

The operation of the TUSB213IRGYR is fairly simple. It communicates between the host and the device using a serial/USB interface, which includes serial/USB1.1 commands and status information. The device is configured using special registers, which can be programmed by the host’s firmware. The registers provide basic configuration information, including the speed (low or full), mode (host or device) and port enable/disable. This allows the device to be customized for different system needs.

When a USB connection is made, the transceiver signals the link speed information to the host, and then begins data transfer operations. The transceiver begins by checking the link speed, and then performs bit rate negotiation. Once the link speed is established, the transceiver then initiates data transfer operations between the host and the device, including arbitration and flow control. Finally, the transfer is completed, and the transceiver then sends the status information back to the host.

Conclusion

The TUSB213IRGYR is a versatile, powerful and highly integrated physical layer transceiver, designed to provide fast and reliable USB 2.0 connectivity to a wide range of mobile products. It features an intuitive serial/USB interface and a range of features and benefits, allowing customers to quickly design, validate and deploy USB products quickly and easily.
