Overview
The DS50PCI402SQE/NOPB is a dual-channel, low-power linear repeater manufactured by Texas Instruments. It supports data rates up to 6.25 Gbps and operates on a single 3.3 V supply voltage. The device features CML input and LVDS output interfaces, designed for signal integrity in high-speed digital applications. It is housed in a WQFN-48 package suitable for surface-mount technology. The component functions as a retimer or linear repeater to extend transmission distances for PCI Express and other serial links.
Feature Summary
- Dual-channel architecture supporting independent signal processing
- Low power consumption optimized for thermal efficiency
- CML to LVDS interface conversion capability
- Supports high-speed serial data transmission up to 6.25 Gbps
Applications
- PCI Express (PCIe) link extension
- Backplane interconnect systems
- Peripheral I/O signal conditioning
Procurement Notes
Verify the specific suffix 'SQE' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with 3.3 V logic levels and check for moisture sensitivity classification before assembly. Confirm RoHS compliance status through the latest environmental documentation provided by Texas Instruments.
Selection Notes
Select this component when a dual-channel solution is required for extending PCIe or similar serial links without complex equalization. Compare power dissipation limits against your system's thermal budget. Verify that the CML input and LVDS output standards align with your source and destination devices. Consider the WQFN-48 footprint constraints during PCB layout planning.
Part Context
This part belongs to the DS50PCI40x series of linear repeaters from Texas Instruments. It is designed to complement other interface solutions like the DS50PCI401. The series focuses on providing reliable signal regeneration for high-speed serial protocols in enterprise and industrial environments.
Replacement Considerations
The DS50PCI401SQE/NOPB is a documented single-channel alternative within the same family. Verify channel count requirements before substitution. No other direct public substitutes are confirmed in the provided reference material.
