Overview
The DS50PCI401SQE/NOPB is a four-channel linear repeater designed for PCI Express applications. It supports data rates up to 5 Gbps per lane, accommodating PCIe Gen 2 specifications. The device operates with a supply voltage range of 2.375 V to 3.6 V and functions within an ambient temperature range of -40°C to +85°C. It utilizes a 48-pin WQFN package with exposed pad for surface mount installation. Key electrical parameters include a propagation delay of 230 ps and an input capacitance of 10 pF. The component integrates I2C/SMBus interface capabilities for configuration control.
Feature Summary
- Provides signal integrity restoration for high-speed serial links through linear equalization and re-driving.
- Supports flexible configuration via integrated I2C or SMBus digital interface for adaptive settings.
- Designed for low power consumption suitable for thermally constrained system environments.
Applications
- PCI Express Gen 2 backplane interconnects
- Peripheral I/O expansion cards
- Front port signal extension
Procurement Notes
Verify the complete part number including the suffix NOPB to confirm lead-free status and RoHS compliance. Confirm the specific package variant matches the design footprint requirements. Check the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.
Selection Notes
Select this component when designing systems requiring four independent lanes of signal regeneration for PCIe Gen 2 standards. Ensure the board layout accommodates the thermal requirements of the WQFN-48 package. Verify that the system power budget aligns with the specified operating current limits under maximum load conditions.
Part Context
This device belongs to the DS50PCI401 series of linear repeaters manufactured by Texas Instruments. It is part of a broader family of interface ICs focused on maintaining signal quality in high-speed digital communication paths. The series is engineered to extend reach and improve eye diagram margins in complex motherboard architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives from the same manufacturer only after verifying functional equivalence and electrical parameter alignment.
