SN65LVPE502BRGER

Overview

The SN65LVPE502BRGER is a dual-channel USB 3.0 redriver and signal conditioner manufactured by Texas Instruments, designed to extend interconnect distances in high-speed serial links. It supports SuperSpeed data rates up to 5 Gbps and complies with the USB 3.0 specification revision 1.0. The device features programmable equalization, de-emphasis, and amplitude swing controls to optimize signal integrity across PCB traces or cables. It operates within a supply voltage range of 3.0 V to 3.6 V and draws a typical operating current of 120 mA per channel. The component is housed in a 24-pin VQFN package (RGE) suitable for surface-mount assembly.

Feature Summary

• Dual-channel architecture supporting independent signal conditioning for two separate USB 3.0 lanes
• Programmable equalization and de-emphasis capabilities to compensate for channel loss and improve eye diagram quality
• Supports USB 3.0 electrical idle conditions and low-frequency periodic signals (LFPS) for power management modes
• Includes dedicated low-power modes such as sleep mode and low-power state when unplugged to reduce energy consumption

Applications

• Extending cable lengths between USB 3.0 hosts and peripheral devices
• Signal regeneration on high-density motherboard traces connecting USB ports to controllers
• USB 3.0 compliance testing environments using evaluation modules

Procurement Notes

Verify the exact suffix 'BRGER' against the official Texas Instruments datasheet to confirm pinout and packaging specifications. Ensure compatibility with the 24-VQFN footprint during layout. Check for end-of-life status or recommended new designations, as older revisions may be marked NRND. Confirm moisture sensitivity level handling requirements prior to soldering.

Selection Notes

Select this component when dual-lane USB 3.0 signal integrity extension is required without active protocol conversion. Compare against single-channel alternatives if only one lane needs boosting. Consider the 120 mA current draw for thermal management in dense enclosures. Verify that the programmable settings align with the specific trace loss characteristics of the target PCB design.

Part Context

This part belongs to the SN65LVPE502 series of USB 3.0 redrivers from Texas Instruments. It is functionally similar to the SN65LVPE502CPRGER but may differ in manufacturing lot or specific package variant details. The series is designed to address signal degradation issues inherent in high-speed USB 3.0 connections over standard interconnects.

Replacement Considerations

The SN65LVPE502CPRGER is a documented alternative within the same family. Other potential substitutes include the SN65LVPE512 series for similar dual-channel applications. Verify pin-to-pin compatibility and software configuration registers before substitution.
