TUSB212QRWBTQ1

TUSB212-Q1是一款USB高速(HS)信号调节器，专为补偿传输通道中的ISI信号损失而设计。 TUSB212-Q1采用了对USB低速(LS)和全速(FS)信号无感知的设计，该设计正在申请专利。LS和FS信号特征不受TUSB212-Q1的影响，但该器件会对HS信号进行补偿。 借助可编程信号交流升压和直流升压，可精调器件性能，从而优化连接器上的高速信号。这有助于通过USB高速电气合规性测试。 此外，TUSB212-Q1符合USB On-The-Go (OTG) 和电池充电(BC)协议。

The TUSB212-Q1 is a USB High-Speed (HS) signal conditioner, designed to compensate for ISI signal loss in a transmission channel. TUSB212-Q1 has a patent-pending design which is agnostic to USB Low Speed (LS) and Full Speed (FS) signals and does not alter their signal characteristics, while HS signals are compensated. In addition, the design is compatible with USB On-The-Go (OTG) and Battery Charging (BC) specifications. Programmable signal gain through an external resistor permits fine tuning device performance to optimize signals helping to pass USB HS electrical compliance tests at the connector. Additional DC boost configurable by three level input DC_BOOST helps overcoming the cable losses. The footprint of TUSB212-Q1 allows a board layout using this device such that it does not break the continuity of the DP/DM signal traces. This permits risk free system design of a complete USB channel with flexible use of one or multiple TUSB212-Q1 devices as needed for optimal signal integrity. This allows system designers to plan for this device and use it only if signal integrity analysis and/or lab measurements sow a need. If such a need is not warranted, the device can be left unpopulated without any board rework.
