Description
General part information
TUSB501-Q1 Series
The TUSB501-Q1 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-Q1 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-Q1 advanced state machine makes it transparent to hosts and devices.
After power up, the TUSB501-Q1 periodically performs receiver detection on the TX pair. If it detects a SuperSpeed USB receiver, RX termination becomes enabled, and the TUSB501-Q1 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-Q1. Likewise, the output driver supports configuration of De-Emphasis and Output Swing (pins DE and OS). These settings allow the TUSB501-Q1 to be flexibly placed in the SuperSpeed USB path, with optimal performance.
