PT4161LRS

Overview

The PT4161LRS is a PCIe Gen 4.0 Smart Retimer from the Aries series by Astera Labs, designed for signal integrity in high-speed interconnects. It features 16 lanes with x16 interface capability and utilizes an FC-CSP-354 package for SMD/SMT mounting. The device supports humidity-sensitive handling and operates within standard industrial temperature ranges. As part of the Aries family, it provides pin-compatible upgrades for PCIe 4.0 architectures, ensuring reliable data transmission across extended traces in server and storage systems.

Feature Summary

Supports PCIe Gen 4.0 architecture with 16-lane connectivity
Pin-compatible design enabling seamless upgrades to PCIe 5.0 solutions
Optimized for cloud-scale deployments and data center environments

Applications

Cloud-scale server interconnects
High-performance storage arrays
AI and machine learning infrastructure

Procurement Notes

Verify component authenticity through authorized Astera Labs distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper ESD protection during handling due to the FC-CSP-354 package type. Cross-reference datasheet revisions to match specific design requirements.

Selection Notes

Select this retimer for designs requiring PCIe 4.0 signal regeneration over long traces. Consider the pin-compatible PT5161L for future-proofing against PCIe 5.0 migration. Evaluate board space constraints against the FC-CSP-354 footprint. Verify thermal management capabilities align with system cooling strategies.

Part Context

The PT4161LRS belongs to the Aries Smart Retimer family, specifically engineered for PCIe 4.0 applications. It addresses signal degradation challenges in modern data centers. The series includes pin-compatible variants like the PT5161L for PCIe 5.0, allowing manufacturers to maintain design continuity while upgrading speeds.

Replacement Considerations

The PT5161L is a pin-compatible alternative offering PCIe 5.0 support. Direct substitution requires verification of electrical characteristics and system compatibility. Consult official documentation for detailed comparison of performance metrics between Gen 4.0 and Gen 5.0 variants.
