DS160PR410RNQR

Overview

The DS160PR410RNQR is a four-channel linear redriver designed for PCI Express Gen 4 applications. It supports data rates up to 25 Gb/s per channel, enabling signal integrity over extended copper traces. The device operates on a single 3.3 V supply with a maximum current consumption of 150 mA. It features a WQFN-40 package (6x4 mm) suitable for surface mount installation. The operational temperature range spans from -40°C to +85°C. Internal I2C control allows configuration of equalization settings to optimize signal performance across various channel lengths and loss conditions.

Feature Summary

• Four independent channels providing linear signal regeneration for high-speed serial links
• Supports PCIe Gen 4 signaling rates up to 25 Gb/s per lane
• Configurable equalization via internal I2C interface for adaptive signal conditioning
• Low power consumption design optimized for dense server and storage architectures

Applications

• PCIe Gen 4 switch and retimer boards in servers
• Storage area network (SAN) backplane interconnects
• High-performance computing accelerator cards
• Active copper cable assemblies for data center connectivity

Procurement Notes

Verify the suffix RNQR corresponds to the WQFN-40 package and tape-and-reel shipping format. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the ordering part number matches the specific pinout and thermal pad requirements for your PCB layout. Cross-reference the datasheet revision date to confirm feature availability.

Selection Notes

Select this component when designing for PCIe Gen 4 speeds requiring linear amplification rather than clock recovery. Compare channel count against system bandwidth needs; this part offers four lanes. Evaluate board trace loss characteristics to determine if the adjustable equalization ranges are sufficient. Consider the WQFN-40 footprint constraints during mechanical design.

Part Context

This device belongs to the DS160PR410 family of linear redrivers from Texas Instruments. It complements other interface solutions like the DS160PR412 switch or DS250DF410 retimer by focusing on passive signal restoration without complex clock data recovery logic. The family targets cost-sensitive yet high-performance PCIe infrastructure markets.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include variants with different suffixes indicating packaging changes. Verify functional equivalence for PCIe Gen 4 support. Alternative families like the DS160PR421 offer switching capabilities but differ in architecture.
