DS25BR440TSQX/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS25BR440TSQX/NOPB is a quad LVDS buffer manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 3125 Mbps and accepts CML, LVDS, or LVPECL input signals while providing LVDS outputs. The device integrates transmit pre-emphasis and receive equalization to maintain signal integrity over long traces. It operates on a single 3.0 V to 3.6 V power supply and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a 40-pin WQFN package with a 6x6 mm footprint.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates four independent LVDS buffers with transmit pre-emphasis and receive equalization capabilities.
• Supports multiple input protocols including CML, LVDS, and LVPECL for flexible system integration.
• Provides low skew performance suitable for high-speed parallel data bus applications.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the full part number with official distributor catalogs to confirm availability and exact packaging details before procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a quad-channel LVDS buffer with active signal conditioning is required. It is appropriate for designs needing support for CML, LVDS, or LVPECL inputs. Consider the 40-pin WQFN package constraints and the 3.3V nominal supply voltage during PCB layout. Verify that the channel count matches the system's data path requirements.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to the DS25BR series of high-speed line transceivers and buffers from Texas Instruments. It shares functional similarities with other members like the DS25BR400 but differs in protocol support and speed ratings. The series is commonly used in display interfaces and high-performance computing systems requiring reliable LVDS signal distribution.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS25BR440TSQ/NOPB is a non-lead-free variant of the same device. Direct substitution requires verifying pin compatibility and ensuring the lead-free status aligns with manufacturing regulations. Other family members may offer different channel counts or speed capabilities.
