Key Features
- Dual-port USB 3.1 Gen 1 SuperSpeed signal re-equalization up to 5 Gbps
- Adjustable receive equalization up to 4 dB for long PCB trace compensation
- Single 3.3 V supply with low propagation delay under 1 ns
- Transparent pass-through operation requiring no firmware or I2C configuration
- 16-pin WQFN package for compact USB hub and dock designs
- Supports both host-side and device-side USB 3.0 retiming applications
Applications
The TUSB1042RNQR is used in USB 3.0 docking stations, laptop port replicators, and industrial panel PCs where long PCB traces or connectors attenuate SuperSpeed USB signals beyond the USB 3.1 Gen 1 loss budget. Its transparent 5 Gbps re-drive capability restores signal integrity without requiring any software stack or register configuration. It also fits embedded computing modules and single-board computers that route USB 3.0 across long flex cables or through multiple connectors.

Frequently Asked Questions
At what data rate does TUSB1042RNQR operate and which USB standard does it target?
TUSB1042RNQR operates at USB 3.1 Gen 1 SuperSpeed data rates of 5 Gbps per channel, re-equalizing and re-amplifying two independent differential pairs with up to 4 dB of receive-side equalization gain to restore signal integrity over lossy PCB traces or cable assemblies.
Does TUSB1042RNQR require any firmware or host driver to function in a USB 3.0 hub design?
No, TUSB1042RNQR operates transparently without any firmware, I2C configuration, or host driver because it is a linear redriver that automatically re-equalizes 5 Gbps SuperSpeed USB signals from a single 3.3 V supply, making it a drop-in addition to existing USB 3.0 hub or dock PCB layouts with no software changes.
How does TUSB1042RNQR extend USB 3.0 reach over PCB traces in a docking station design?
TUSB1042RNQR compensates up to 4 dB of insertion loss from long PCB traces—typically 10 to 15 inches at 5 Gbps—by applying adaptive receive equalization before re-driving the signal, which allows designers to route USB 3.1 Gen 1 signals across connector transitions and extended board lengths in docking stations or industrial panel PCs without violating the USB 3.0 eye-diagram mask.
