SN75LVPE5412RUAR

Overview

The SN75LVPE5412 is a four-channel linear redriver with an integrated 1:2 demultiplexer designed for PCIe 5.0 and interfaces up to 32Gbps. It operates on a single 3.3V supply, consuming 720mW active power without requiring a heatsink. The device features continuous-time linear equalizers (CTLE) providing up to 24dB boost at 16GHz. Key electrical parameters include a low latency of 90ps, additive random jitter of 55fs RMS, and excellent differential return loss of -10dB from 8-16GHz. It supports x4, x8, and x16 bus widths and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Protocol agnostic linear redriver compatible with PCIe, UPI, CCIX, NVLink, DisplayPort, SAS, SATA, and XFI.
• Integrated 1:2 demultiplexer allows support for x4, x8, and x16 bus widths using one or multiple devices.
• Internal voltage regulator provides immunity to supply noise for high-speed data paths.
• Automatic receiver detection ensures seamless support for PCIe link training.

Applications

• Desktop PC and motherboard
• Rack server, microserver, and tower server
• High performance computing and hardware accelerator
• Data storage and network attached storage
• Storage area network (SAN) and host bus adapter (HBA) card

Procurement Notes

Verify the specific ordering suffix RUAR corresponds to the 42-pin WQFN package configuration. Confirm that the component meets the required operating temperature range of -40°C to 85°C for your application environment. Ensure proper handling procedures are followed due to the sensitivity of the high-speed interface components during assembly.

Selection Notes

Select this component when extending PCIe 5.0 links up to 32Gbps with minimal signal degradation. The integrated demux functionality simplifies board layout for x8 and x16 configurations compared to standard redrivers. Consider the low power consumption and lack of thermal requirements for space-constrained designs where heat dissipation is challenging.

Part Context

This device belongs to Texas Instruments' family of high-speed linear redrivers and repeaters. It complements the SN75LVPE5421 multiplexer variant to provide complete mux/demux solutions for complex PCIe topologies. The series addresses the increasing channel loss challenges associated with next-generation high-speed serial interfaces.

Replacement Considerations

The SN75LVPE5421 serves as a companion part offering multiplexing capabilities rather than direct replacement. Verify pin compatibility if substituting with other TI redrivers, noting differences in integration levels such as the absence of a demux in standard models.

FAQ
