Description
General part information
TUSB501 Series
The TUSB501 is a 3rdgeneration 3.3-V USB 3.0 single-channel redriver. When 5 Gbps SuperSpeed USB signals travel across a PCB or cable, signal integrity degrades due to loss and inter-symbol interference. The TUSB501 recovers incoming data by applying equalization that compensates channel loss, and drives out signals with a high differential voltage. This extends the possible channel length, and enables systems to pass USB 3.0 compliance. The TUSB501 advanced state machine makes it transparent to hosts and devices.
After power up, the TUSB501 periodically performs receiver detection on the TX pair. If it detects a SuperSpeed USB receiver, RX termination becomes enabled, and the TUSB501 is ready to redrive.
The receiver equalizer has three gain settings that 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 configuration of De-Emphasis and Output Swing (pins DE and OS). These settings allow the TUSB501 to be flexibly placed in the SuperSpeed USB path, with optimal performance.
