SN65LVPE502CP1RGER

Overview

The SN65LVPE502CP is a dual-channel, single-lane USB 3.0 redriver and signal conditioner supporting data rates of 5.0 Gbps. It complies with USB 3.0 specification revision 1.0, supporting electrical idle conditions and low frequency periodic signals (LFPS) for power management modes. The device features programmable equalization, de-emphasis, and amplitude swing control to extend interconnect distances. It operates from a single 3.3V supply with typical active power consumption of 315 mW. Key parameters include a maximum data rate of 5 Gbps, an operating temperature range of 0°C to +85°C, and a supply voltage range of 3V to 3.6V.

Feature Summary

• Provides high protection against ESD transients with HBM ratings up to 5,000 V.
• Supports selectable equalization, de-emphasis, and output swing control via hardware pins.
• Integrates termination resistors and supports hot-plug capabilities.
• Enables low active power operation in U0 state and supports USB 3.0 low power modes.

Applications

• Notebooks
• Desktops
• Docking Stations
• Active Cables
• Backplanes

Procurement Notes

Verify the specific ordering suffix (e.g., RGER vs RGET) as it determines the tape and reel packaging quantity. Confirm current production status, as this component may be classified as NRND (Not Recommended for New Designs). Ensure compliance with moisture sensitivity levels and storage handling requirements specified in the datasheet before procurement.

Selection Notes

Select based on required channel count and interface speed. This device is optimized for USB 3.0 SuperSpeed applications at 5 Gbps. Consider the available pin configurations for equalization and de-emphasis settings if custom signal conditioning is needed. Verify that the thermal performance of the 24-pin QFN package meets the system's heat dissipation requirements under maximum load conditions.

Part Context

The SN65LVPE502CP belongs to Texas Instruments' LVPE502 series of USB 3.0 redrivers. It is designed to compensate for signal loss and jitter in high-speed serial links. The device serves as a bridge between host controllers and peripheral devices, ensuring signal integrity over extended PCB traces or cables.

Replacement Considerations

Check for direct replacements within the same family, such as the SN65LVPE502CPRGET, which shares identical functionality but differs in reel size. Evaluate alternative USB 3.0 redriver ICs from other manufacturers if the NRND status impacts long-term availability.

FAQ

How does the device handle USB 3.0 low power states?

The device supports USB 3.0 low power modes by detecting electrical idle conditions and LFPS signals. It can enter sleep mode or U2/U3 modes to reduce power consumption significantly when no data activity is detected.

What is the input impedance of the receiver?

The DC differential input impedance is typically 80 Ω, ranging from 72 Ω to 120 Ω. The DC common mode impedance is typically 23 Ω, ranging from 18 Ω to 30 Ω.

Can the equalization settings be adjusted dynamically?

No, the equalization, de-emphasis, and output swing settings are configured statically using the EQx, DEx, and OSx control pins during initialization. They cannot be changed dynamically during operation.
