Texas Instruments introduced the industry's first standalone USB 2.0 redriver. The high-speed two-way TUSB211 redriver is AEC-Q100 qualified to improve USB signal integrity in automotive infotainment systems.
Compared with existing hub solutions, the power consumption of the device is reduced by more than 40%; the compact pin layout can reduce the overall solution size; and the built-in calibration function can speed up system evaluation and optimization. These features enable designers to significantly reduce the size, cost, and power consumption of automotive infotainment systems that provide navigation, mobile docking, and other multimedia capabilities.
Key Features: 1-Simplified Evaluation: Unlike existing hub solutions, there is no continuity interruption on the printed circuit board (PCB) of the TUSB211. This allows existing signals to flow and eliminates the need to interrupt routing when adding a redriver to the PCB. 2-Ultra-low power consumption: In active mode, the power consumption of the TUSB211 is less than 55mW-Compared with existing hub solutions, the power consumption is reduced by 40% without affecting speed. It supports USB data rates up to 480 Mbps. 3-Small footprint: The redriver is in a 1.6mm x 1.6mm, 12-pin ultra-thin quad flat no-lead (X2QFN) package. Compared with industry standard packages, its package size is reduced by 60%, thereby eliminating demand Large hub. 4-Fully compliant with USB standards: TUSB211 with USB1.0 / 1.1, USB 2.0, USB On-the-Go (OTG) and Battery Charging (BC) 1.2 protocols. The device's bidirectional capability can dynamically improve signal quality in both directions, regardless of the host or peripheral device.
To simplify the design of USB 2.0 systems, engineers can order an evaluation module (EVM) TUSB211RPTREVM, which includes TI's LP5907 single-channel LDO. In addition, engineers can use the USB 2.0, USB 3.0 redrive dongle TI Designs reference designs to quickly get started with their designs.
