SN65LVPE501RGET

Overview

The SN65LVPE501RGET is a dual-channel, single-lane PCI Express redriver manufactured by Texas Instruments. It supports data rates up to 5 Gbps and operates within a supply voltage range of 3 V to 3.6 V. The device draws a maximum operating supply current of 101 mA and exhibits a propagation delay of 280 ps. It utilizes CML input and output signaling standards. The component is housed in a 24-VQFN package with dimensions of 4x4 mm and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides signal conditioning through input equalization and output de-emphasis capabilities.
• Supports electrical idle conditions and low-frequency periodic signals (LFPS) for power management modes.
• Includes programmable equalization, de-emphasis, and amplitude swing settings to extend interconnect distances.

Applications

• PCI Express Gen 1 and Gen 2 link extension
• Signal integrity restoration on high-speed digital boards
• USB 3.0 compliance testing environments

Procurement Notes

Verify the specific ordering suffix RGET to confirm the 24-VQFN package type and reel packaging configuration. Ensure that the design accounts for moisture sensitivity level 2 requirements during storage and assembly processes. Confirm that the 3.3 V nominal supply voltage aligns with the system power architecture before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring dual-channel signal regeneration for PCIe or USB 3.0 interfaces at speeds up to 5 Gbps. Consider the 24-VQFN footprint constraints and the 101 mA current consumption profile against available board space and thermal dissipation capabilities. Verify compatibility with CML signaling standards used in the target application.

Part Context

This part belongs to the SN65LVPE501 family of linear redrivers designed for high-speed serial applications. It serves as a signal conditioner to mitigate channel loss in PCB traces and cables. The device is distinct from retimers as it performs analog signal regeneration rather than clock recovery.

Replacement Considerations

The PI3EQX7841ZDEX from Diodes Incorporated is documented as a similar replacement option. Evaluate pinout compatibility and parameter alignment before substituting.
