When 5 Gbps SuperSpeed – 126 mW Active Power USB signals travel across a PCB or cable, signal – 20 mW in U2/U3 integrity degrades due to loss and inter-symbol interference. The TUSB501 recovers incoming data – 3 mW with No Connection by applying equalization that compensates channel • Automatic LFPS DE Control loss, and drives out signals with a high differential • Excellent Jitter and Loss Compensation voltage. This extends the possible channel length, and enables systems to pass USB 3.0 compliance. – 32 inches of FR4 4 mil Stripline The TUSB501 advanced state machine makes it – 3 m of 30 AWG cable transparent to hosts and devices. • Integrated Termination After power up, the TUSB501 periodically performs • Small 2 x 2 mm QFN Package receiver detection on the TX pair. If it detects a • Selectable Receiver Equalization, Transmitter SuperSpeed USB receiver, RX termination becomes De-Emphasis and Output Swing enabled, and the TUSB501 is ready to redrive. • Hot-Plug Capable The receiver equalizer has three gain settings that • ESD Protection ±5 kV HBM are controlled by pin EQ: 3 dB, 6 dB, and 9 dB. This should be set based on amount of loss before the TUSB501. Likewise, the output driver supports APPLICATIONS configuration of De-Emphasis and Output Swing (pins • Cell Phones, Computers, Docking Stations, DE and OS). These settings allow the TUSB501 to be TVs, Active Cables, Backplanes flexibly placed in the SuperSpeed USB path, with optimal performance. Over previous generations, the TUSB501 features reduced power in all link states, a stronger OS option, improved receiver equalization settings, and an intelligent LFPS Controller. This controller senses the low frequency signals and automatically disables driver de-emphasis, for full USB 3.0 compliance. The TUSB501 is packaged in a small 2 x 2 mm QFN, and operates through an industrial temperature range of –40°C to 85°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
