DS64BR401SQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS64BR401SQ/NOPB is a quad bidirectional redriver manufactured by Texas Instruments, designed for high-speed signal integrity in demanding environments. It supports data rates up to 6.4 Gbps and operates on a single 2.5 V power supply with a typical operating current of 380 mA. The device is housed in a WQFN-54 package suitable for surface mount technology. It functions within an extended industrial temperature range from -10°C to +85°C. This component integrates input equalization and output de-emphasis capabilities to mitigate channel loss.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides four bidirectional channels for simultaneous signal transmission and reception
• Integrates adaptive input equalization to compensate for high-frequency channel attenuation
• Includes programmable output de-emphasis to optimize signal eye diagrams
• Supports multiple signaling standards including PCIe, SAS, and SATA

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'SQ' indicates qualified automotive or extended industrial grade specifications compared to standard variants. Confirm the 'NOPB' designation ensures lead-free packaging compliance with RoHS directives. Cross-reference the manufacturer part number against official datasheets to ensure functional equivalence before integration into design files.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring bidirectional signal regeneration at speeds up to 6.4 Gbps. Ensure the PCB layout accommodates the WQFN-54 package dimensions and thermal requirements. Verify that the system power budget aligns with the 2.5 V supply voltage and 380 mA current consumption specifications provided in the electrical characteristics table.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to the DS64BR401 series of high-speed interface repeaters. It complements other Texas Instruments signal conditioning components by offering bidirectional functionality, distinguishing it from unidirectional buffers. The series targets data center and enterprise storage applications where signal integrity over long traces is critical.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative quad-channel redrivers only if they match the 6.4 Gbps rate, 2.5 V supply, and WQFN-54 footprint constraints.
