The TUSB213QRGYRQ1 is a high-performance, low-latency, multiple-path, and dynamically programmable USB 2.0 transceiver. It supports Dynamic Reconfiguration Port (DRP) techniques to provide up to 30 simultaneous high-speed ports and eight enhanced high-speed ports with forward, backward, and bidirectional compatibility. The TUSB213QRGYRQ1 integrates a USB 2.0 PHY and dual logic cores, while allowing designers to configure one or multiple functions in the same device. It can be used as an interface between a high-speed USB memory, USB cameras, and host microcontrollers.

The TUSB213QRGYRQ1 has several practical applications in the industrial, consumer, and embedded equipment fields. It can be used as an interface in industrial and consumer equipment, such as USB cameras, USB flash drives, and USB audio equipment. It also enables high-bandwidth transfer and storage of audio-visual data from cameras and other digital devices. The device is also used as a bridge between host interfaces, such as USB 2.0 and USB 3.0, reducing board space and complexity, as well as cost.

The working principle of the TUSB213QRGYRQ1 is based on a dual logic core architecture. The core consists of two identical logic blocks devoted to USB 2.0 traffic on the same USB port. Both logic blocks transfer data in a specific order, instead of simultaneously like traditional USB controllers. This significantly reduces USB bandwidth overhead when one core is busy transferring data, while the other is idle. The device manages real-time protection of the incoming and outgoing data, as well as maintaining low latency.

The dual logic core also enables advanced Fast Mode Support, allowing multiple ports to be active at the same time. This provides up to 30 high-speed ports, with 8 ports supporting unbounded bidirectional transfers. For example, an audio streaming application can use one logic core to receive multiple audio streams and the other to output multiple audio streams.

The TUSB213QRGYRQ1 employs enhanced "functional" testing techniques that guarantee compliance with the USB specification, including real-time power control. This protects the device against power surges and helps to conserve energy. In addition, the device also offers immunity from interference from other nearby devices.

In summary, the TUSB213QRGYRQ1 is an ideal solution for USB 2.0 and USB 3.0 interface solutions. It is highly reliable and provides multiple functions while allowing designers to configure devices more quickly and efficiently. It is especially useful for industrial and consumer applications that require high bandwidth transfer of audio-visual data.
