Overview
The TUSB1142IRNQT is a USB Type-C 10Gbps USB 3.2 linear redriver featuring a 2:1 Mux or 1:2 DeMux function, designed for placement between a host/device and a USB-C receptacle. It supports USB 3.2 Gen2 (10Gbps) and Gen1 (5Gbps) data rates along with low power states including Disconnect, U1, U2, and U3. The device incorporates adaptive receiver equalization (AEQ) to automatically determine optimal ISI compensation settings, improving interoperability. It operates from a single 3.3V supply within a 40-pin WQFN package measuring 6mm x 4mm.
Feature Summary
- Adaptive receiver equalization (AEQ) feature that automatically determines the best ISI compensation settings between the device and the connected USB device.
- Configurable choice between adaptive or fixed receiver equalization for ports facing the USB connector.
- Selectable linear or limited redriver configuration for the port facing the system transmitter.
- Advanced USB power management supporting active, disconnect, and disabled states with specific power consumption levels.
Applications
- Notebooks and desktops
- Docking stations
- Data storage devices
- Connected peripherals and printers
Procurement Notes
Verify the component against the official Texas Instruments datasheet SLLSFL2A to confirm pinout compatibility and electrical specifications. Ensure the I2C address configuration via SSEQ pins matches the system design requirements. Check thermal performance metrics if operating in high-density environments. Confirm the package orientation and soldering profile align with assembly guidelines.
Selection Notes
Select this component when a USB Type-C application requires signal integrity restoration for 10Gbps data transmission. The integrated AEQ simplifies design by reducing manual equalization tuning. Consider the 40-pin WQFN package size for space-constrained layouts. Verify that the system supports the required 3.3V supply voltage and I2C communication protocol for configuration.
Part Context
This part belongs to the TUSB1142 series of USB Type-C linear redrivers. It is specifically engineered for USB 3.2 applications requiring multiplexing capabilities. The 'I' suffix indicates an industrial temperature range rating, while 'RNQT' denotes the 40-pin WQFN package and tape-and-reel packaging format.
Replacement Considerations
Direct substitutes include other Texas Instruments USB Type-C redrivers with similar mux/deMUX functionality, such as the TUSB1044A series, provided they support the required 10Gbps data rate and package dimensions. Verify pin-to-pin compatibility and electrical characteristics before substitution.
