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.
