DS50PCI401SQ/NOPB

Overview

The DS50PCI401SQ/NOPB is a dual-channel linear redriver designed for PCI Express 3.0 applications, manufactured by Texas Instruments. It operates within a supply voltage range of 2.375 V to 3.6 V and supports data rates up to 8.0 Gbps per channel. The device features an adjustable equalization control with four selectable tap settings to compensate for signal loss in printed circuit board traces. It utilizes CML input and output interfaces and is housed in a WQFN-48 package suitable for surface-mount assembly. The component functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides dual-channel signal regeneration for high-speed serial links
• Features adjustable equalization with multiple tap configurations
• Supports low-power operation modes for energy efficiency

Applications

• PCI Express 3.0 backplane interconnects
• Server and storage system front-panel connections
• High-performance computing motherboard trace extension

Procurement Notes

Verify the specific suffix 'SQ' against the manufacturer's official datasheet to confirm the qualified operating temperature range and packaging details. Ensure that the NOPB designation aligns with current RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing systems requiring signal integrity restoration for PCI Express 3.0 standards. Evaluate the required trace length and insertion loss to determine if the available equalization taps are sufficient. Consider the power consumption characteristics relative to the system's thermal constraints and verify compatibility with the host controller's electrical interface specifications.

Part Context
