DESCRIPTION
The TUSB501 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 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.
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
