Overview
The TUSB1004IRNQT is a quad-channel linear redriver supporting USB 3.2 Gen1 (5 Gbps) and Gen2 (10 Gbps) standards. It operates from a single 3.3 V supply with a voltage range of 3.0 V to 3.6 V. The device features adaptive receiver equalization (AEQ) with up to 16 settings providing up to 12 dB gain at 5 GHz. It supports two independent USB Type-A ports, configurable via I2C or pin-strap modes. Active power consumption is typically 550 mW for dual ports, while disabled power is 0.130 mW. Operating temperatures range from -40°C to +85°C for the 'I' suffix variant.
Feature Summary
- Adaptive receiver equalization automatically determines optimal ISI compensation settings between the device and connected USB peripherals.
- Configurable transmitter output stages allow selection between linear or limited redriver modes for system-facing ports.
- Supports advanced USB low-power states including Disconnect, U1, U2, and U3 with distinct power profiles.
- Dual configuration methods enable operation through I2C interface or hardware pin-strapping.
Applications
- Notebooks and desktop computers
- Docking stations
- Data storage devices
- Connected peripherals and printers
Procurement Notes
Verify the specific temperature grade required for the application environment. The 'I' suffix indicates an extended operating range of -40°C to +85°C, whereas the standard version covers 0°C to 70°C. Confirm package availability in the 40-pin WQFN format and ensure I2C address configurations match the system design constraints before ordering.
Selection Notes
Select this component when signal integrity degradation requires active compensation for USB 3.2 channels. Ensure the host controller supports the required data rates and that the PCB layout accommodates the necessary AC coupling capacitors. Verify that the I2C bus capacitance limits are respected if using digital configuration rather than pin-strapping.
Part Context
This part belongs to the TUSB1004 family of USB 3.2 linear redrivers designed for Type-A receptacles. It serves as a signal conditioning bridge between host controllers and USB connectors, compensating for channel loss in high-speed differential pairs. The device integrates thermal management capabilities within its compact WQFN footprint.
Replacement Considerations
Public confirmed substitute part numbers: None identified in verified documentation.
FAQ
How does the AEQ feature function?
The Adaptive Equalizer (AEQ) automatically determines the best Inter-Symbol Interference (ISI) compensation settings between the TUSB1004 and the USB device plugged into the connector, improving interoperability without manual tuning.
What is the maximum I2C clock frequency?
The device supports an I2C clock frequency of up to 1 MHz.
Can the transmitter stage be configured as a limited redriver?
Yes, for ports facing the system (SSRX1/2 transmitters), the user can choose between linear redriver mode or limited redriver mode.
