3 Description

The TUSB501-Q1 is a 3rd generation 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.

Over previous generations, the TUSB501-Q1 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-Q1 is packaged in a small 2 x 2 mm QFN, and operates through an industrial temperature range of –40°C to 105°C.
