The TUSB1002IRMQT is a small, low power, low voltage (1.8-3.3V), USB 2.0 compliant transceiver that enables data transfer over an infra-red (IR) interface. It was designed to solve the challenge of communicating from USB-enabled devices to devices that lack a USB connection. It is the first of its kind to drive the 420mA signal current for full USB bandwidth capabilities.

Application field of TUSB1002IRMQT

TUSB1002IRMQT is ideally suited for applications in consumer and industrial automation, medical, automotive and other industries. Specifically, it can be used in remote control applications and to bridge the IR interface with USB to enable data transfer and audio streaming. Examples of applications include streaming video from set-top boxes to displays, transferring data to and from medical equipment, driving remote control of industrial systems, and providing USB control over an IR network.

Working Principle of TUSB1002IRMQT

TUSB1002IRMQT is a circuit of transceiver and receiver. The transceiver is the interface between the host device and the receiver, and the receiver is the interface with the device on the other side of the connection. TUSB1002IRMQT combines the two with a single IC, which helps reduce complexity and reduces board space.

The IC consists of two main components: a Transmit driver and a Receive buffer. The transmit driver sends data over the IR interface, while the receive buffer receives data from the IR interface. The IC is designed to be compliant with USB 2.0 and supports speeds up to 480 Mbps. The data rate is dependent on the operating temperature and supply voltage.

The receive buffer of the IC works together with the receiver to interpret signals sent over the IR interface. The data is then sent to the host device as USB data packets. The transmit driver works similarly, transforming information sent from the host device into data packets for transmission over the IR interface.

The TUSB1002IRMQT also features Automatic Data Retrieval, which ensures correct data transmission even in the presence of noise. The IC can detect and correct errors in the data stream using forward error correction (FEC) techniques. In addition, the IC includes circuitry to detect various IR modulation techniques, allowing operation with various IR devices.

The TUSB1002IRMQT is the first of its kind, and its development has enabled users to enjoy the convenience of a USB connection even when an IR connection is desired. Its low power consumption and small size make it ideal for applications in various industries including medical, automotive, industrial automation, and consumer devices.
