SN65LVPE512RMQR

Overview

The SN65LVPE512RMQR is a dual-channel USB 3.0 redriver manufactured by Texas Instruments, designed to extend interconnect distances for high-speed serial links. It supports data rates up to 5Gbps and operates within a supply voltage range of 3V to 3.6V. The device features programmable equalization and de-emphasis capabilities to compensate for signal loss in PCB traces and cables. It utilizes a 24-WQFN (3x3) surface-mount package with an exposed thermal pad. The component draws approximately 100mA to 120mA of supply current and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture supporting independent signal conditioning for two separate lanes
• Programmable equalization and de-emphasis to optimize signal integrity over lossy channels
• Supports USB 3.0 electrical idle conditions and low-frequency periodic signals for power management
• Includes dedicated shutdown and enable pins for flexible system power control

Applications

• Extending cable or trace lengths between USB 3.0 hosts and devices
• Signal regeneration in high-density motherboard layouts requiring USB 3.0 connectivity
• USB compliance testing environments utilizing specific transmitter validation modes

Procurement Notes

Verify the obsolete status indicated as NRND before initiating new designs, as this part is not recommended for future use. Confirm package compatibility with the 24-WQFN footprint and ensure thermal relief requirements are met during assembly. Check for active replacement alternatives from the manufacturer if long-term supply stability is required for production cycles.

Selection Notes

Select this component when dual-lane USB 3.0 signal extension is necessary without full retiming functionality. Ensure the design accommodates the CML input/output interface requirements and provides adequate decoupling for the specified supply voltage range. Consider the physical dimensions of the 3x3mm package when determining board space allocation.

Part Context

This device belongs to the SN65LVPE512 series of linear redrivers from Texas Instruments. It is functionally related to other USB 3.0 interface solutions like the SN65LVPE502CP but offers distinct packaging and pinout configurations. The RMQR suffix specifically denotes the reel-based packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

The SN65LVPE512RGER is listed as a similar alternative within the same product family. Verify pin-to-pin compatibility and functional equivalence before substitution, particularly regarding the package type differences between RQR and RGER suffixes.
