TUSB1142RNQT

Overview

The TUSB1142RNQT is a USB Type-C 2:1 MUX/DeMux adaptive linear redriver designed for USB 3.2 applications. It supports data rates of 5Gbps and 10Gbps, accommodating USB 3.2 Gen1 and Gen2 standards along with low power states (Disconnect, U1, U2, U3). The device operates from a single 3.3V supply within a 40-pin WQFN package (6mm x 4mm) and features an operating temperature range of 0°C to 70°C. Key electrical parameters include active power consumption of 550mW (typical), disconnect power of 1.5mW, and disabled power of 0.130mW. It provides 16 EQ settings offering up to 12dB gain at 5GHz.

Feature Summary

Incorporates Adaptive Receiver Equalization (AEQ) to automatically determine optimal ISI compensation settings between the device and connected USB equipment.
Supports advanced USB power management with distinct low-power modes for Disconnect, U1, U2, and U3 states.
Offers configurable receiver equalization for ports facing the USB connector and selectable linear or limited redriver options for system-facing ports.

Applications

Notebooks and desktop computers
Docking stations
Data storage devices
Connected peripherals and printers

Procurement Notes

Verify the specific ordering suffix RNQT against the manufacturer's current orderable addendum to confirm the commercial temperature range (0°C to 70°C) and package dimensions. Ensure compatibility with I2C or pin-strap configuration requirements during procurement planning.

Selection Notes

Select this component for designs requiring a 2:1 multiplexer function in USB Type-C host or device interfaces. Consider the 40-pin WQFN footprint and thermal characteristics when designing the PCB layout. Verify that the system environment remains within the specified 0°C to 70°C operating temperature range.

Part Context

This part belongs to the TUSB1142 series of USB Type-C redrivers. The RNQT suffix denotes the commercial temperature grade variant housed in a 40-pin WQFN package. Other variants in the series may offer industrial temperature ranges or different packaging options.
