FEATURES
DESCRIPTION
The TUSB501 is a 3rd generation 3.3-V USB 3.0
2
Aggressive Low-Power Architecture (Typ):
single-channel redriver. 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

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

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

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,

configuration of De-Emphasis and Output Swing (pins
Cell Phones, Computers, Docking Stations,
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.
