USB3347-CP-TR

USB3347-CP-TR Application Field and Working Principle

The USB3347-CP-TR is a fully integrated USB 3.0 type-A USB device controller, transmitter and receiver solution. It can convert the USB 2.0 data to USB 3.0. This integrated solution is designed to reduce the power, design time, and cost of USB 3.0 products. It also supports low-speed, full-speed and high-speed USB 3.1 Gen1/Gen2 data rates, allowing the device to easily reach compliance at up to 2.5 Gbps.

The USB3347 is a controller, transmitter, and receiver which route, via a high-speed serial bus, the data sent by the USB 3.0 controller to the peripheral device and vice versa. This enables the USB 3.1 Gen1/Gen2 data rates to be up to 2.5Gbps. This device works with a high-speed serial bus to provide a forward-channel type communication interface between the host application, the USB 3.0 device, and the peripheral device.

Functional Overview

The USB3347-CP-TR provides a high-speed bus to support up to 2.5 Gbps data rate. The USB3347-CP-TR also implements several important USB 3.1 protocol functions such as USB power management, management of interrupt and bulk transfers, and simultaneous integration and implementation of the USB 3.0 and 3.1 specifications. The USB3347-CP-TR features two transmitters and receivers which are mutually compatible and assignable to different peripheral devices. The integrated solution simplifies the device design and reduces the total number of external components required.

Application Fields

The USB3347-CP-TR is suitable for applications such as external storage devices, USB accessories, docking stations, and other USB peripheral devices. It provides market-leading performance and integration for a wide range of applications in desktop, mobile, and embedded computing systems. The USB3347-CP-TR is also suitable for USB-C view and DisplayPort applications.

Working Principle

The USB3347-CP-TR solution is composed of two components, a USB Host Controller Interface (HCI) and an USB 3.0 Link interface. The USB Host Controller bridges the USB 2.0 and USB 3.0 interface and is responsible for providing data integrity and flow control. The USB 3.0 Link interface is responsible for transmitting the data from an attached USB peripheral device to the USB Host controller. The USB3347-CP-TR uses the USB 3.0 Link/ PHY interface to enable high speeds over short distances, so it is important to maintain good physical link integrity when using the device.

The USB3347-CP-TR has two primary components: a USB3.0-compliant Host Controller Interface (HCI) and a USB 3.0 Link Protocol (LPP) interface. The USB 3.0 LPP provides a direct link between the host and device using a high-speed serial bus. The USB3347-CP-TR supports both USB 2.0 and USB3.0 devices, and can be used in applications with the USB 3.1 and USB 3.2 specifications. The USB 3.1 Gen1 and Gen2 capabilities of the USB3347-CP-TR minimizes the need for USB 2.0 subsystems, as it supports both Gen1 and Gen2 at 2.5 Gbps speeds.

Conclusion

The USB3347-CP-TR is a fully integrated USB 3.0 type-A USB device controller, transmitter and receiver solution. It supports both USB 2.0 and USB 3.0 standards, allowing it to be used in a variety of applications, ranging from external storage devices to portable devices, docks and displays. It also supports low-speed, full-speed and high-speed USB 3.1 Gen1/Gen2 data rates, allowing the device to easily reach maximum performance at up to 2.5 Gbps.
