TUSB1002IRMQR

Drivers, Receivers, Transceivers Overview

The TUSB1002IRMQR is a dual-channel USB 3.1 SuperSpeedPlus linear redriver and signal conditioner manufactured by Texas Instruments. It supports data rates of 5 Gbps (SuperSpeed) and 10 Gbps (SuperSpeedPlus), as well as PCI Express Gen3, SATA Express, and SATA Gen3. The device operates on a single 3.3 V supply with an ultra-low-power architecture, consuming less than 340 mW in active mode and under 8 mW in U2/U3 states. It features adjustable voltage output swing up to 1200 mVpp and provides up to 16 dB of linear equalization at 10 Gbps across 16 settings. Packaged in a 4 mm x 4 mm VQFN, it includes hot-plug capability and ±6 kV HBM ESD protection.

Drivers, Receivers, Transceivers Feature Summary

• Dual-channel linear equalizer compensates for channel loss and inter-symbol interference to extend cable length and ensure compliance.
• Configurable via hardware pins to adjust DC equalization gain and voltage output swing linear range without host/device side requirements.
• Supports USB 3.1 low power modes including U0, U1, U2, and U3 for optimized energy efficiency during idle and disconnected states.

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number against the manufacturer's official orderable addendum to confirm package type and temperature grade. Ensure the specific suffix matches the required commercial grade and VQFN packaging specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring signal integrity restoration for USB 3.1 or PCIe Gen3 links over PCB traces or cables. Verify that the application environment remains within the 0°C to 70°C operating temperature range and utilizes a stable 3.3 V supply rail.

Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' family of USB 3.1 signal conditioners. It serves as a pin-to-pin compatible replacement for legacy LVPE502A and LVPE512 USB 3.0 redrivers, allowing for direct upgrades in existing designs while adding support for higher 10 Gbps data rates.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed pin-to-pin compatible substitutes include the LVPE502A and LVPE512. Verify that the replacement device meets the specific thermal and electrical requirements of the target design.

Drivers, Receivers, Transceivers FAQ

How is the equalization level configured?

The equalization level for each channel is controlled by two configuration pins (e.g., CH1_EQ1 and CH1_EQ2). These pins are sampled after the rising edge of the EN pin to select one of 16 available settings.

What is the function of the SLP_S0# pin?

Asserting SLP_S0# low disables receiver detect functionality. In U2/U3 modes, it keeps Rx termination enabled but disables LOS and LFPS detection. In disconnect states, it disables both detection and termination.

Does the device support AC coupling?

Yes, external AC coupling capacitors are recommended on the differential pairs. The datasheet specifies a range of 75 nF to 265 nF, with 330 nF being optional but highly recommended for RX2P/N if not DC-coupled.
