DS160PR412RUAT

Overview

The DS160PR412RUAT is a four-channel linear redriver with an integrated 1:2 demultiplexer designed for PCIe 4.0 and other high-speed interfaces up to 16 Gbps. It operates on a single 3.3 V supply rail, consuming approximately 120 mW per channel in active mode. The device provides continuous-time linear equalization (CTLE) with up to 17 dB boost at 8 GHz to compensate for interconnect loss. Key electrical parameters include a maximum data rate of 16 Gbps, input/output differential return loss of -13 dB and -15 dB respectively, and low additive random jitter of 70 fs. Latency is specified at 80 ps typical. It supports configuration via pin control or SMBus/I2C and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 1:2 demultiplexer alongside four-channel linear redriver functionality for signal integrity extension.
• Features continuous-time linear equalizers (CTLE) to mitigate inter-symbol interference from PCB traces and cables.
• Supports protocol-agnostic operation compatible with UPI, DisplayPort, SAS, SATA, and XFI standards.
• Includes automatic receiver detection and seamless support for PCIe link training state machines.

Applications

• Desktop PC and motherboard expansion slots
• Rack servers and microservers
• High performance computing hardware accelerators
• Network attached storage and host bus adapter cards

Procurement Notes

Verify the specific ordering suffix RUAT corresponds to the WQFN-42 package variant when sourcing. Confirm that the component meets RoHS compliance requirements for the target assembly process. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the manufacturer datasheet revision history to confirm documentation accuracy prior to final design approval.

Selection Notes

Select this component when extending PCIe 4.0 links requires both signal regeneration and lane demultiplexing capabilities. Evaluate the required equalization depth against the passive channel insertion loss to ensure the CTLE range is sufficient. Consider the power consumption constraints relative to the available thermal dissipation in the enclosure. Verify interface compatibility if deploying in non-PCIe applications such as SAS or DisplayPort systems.

Part Context

This part belongs to the DS160PR412 series, which includes variants like the DS160PR412RUAR differing primarily in packaging quantities. The series is designed to complement mux counterparts like the DS160PR421 for complete lane management solutions. It serves as a bridge between high-speed source devices and long-distance passive channels in complex server architectures.

Replacement Considerations

The DS160PR412RUAR is a parameter-equivalent alternative offering identical functional specifications. Verify package dimensions and pinout compatibility before substitution. Ensure that any changes in reel packaging do not impact existing automated pick-and-place equipment settings.
