DS25BR440TSQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS25BR440TSQ/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a quad LVDS buffer with transmit pre-emphasis and receive equalization capabilities, supporting data rates up to 3125 Mb/s. The device accepts CML, LVDS, or LVPECL input signals and converts them to LVDS outputs. It operates on a single 3.3 V supply voltage, with a minimum operating voltage of 3 V and a maximum of 3.6 V. The component features four drivers and four receivers, housed in a 40-pin WQFN package measuring 6 x 6 mm. It supports an operating temperature range from -40°C to +85°C and exhibits a propagation delay of 60 ps.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates transmit pre-emphasis and receive equalization to maintain signal integrity over high-speed links.
• Provides flexible input compatibility by accepting CML, LVDS, and LVPECL logic levels.
• Converts multiple input protocols into standardized LVDS outputs for robust transmission.

Signal Buffers, Repeaters, Splitters Applications

• High-speed serial communication interfaces requiring signal buffering and re-driving.
• Data center server and storage area network backplane connections.
• Peripheral I/O expansion systems utilizing LVDS standards.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the procurement request matches the exact part number DS25BR440TSQ/NOPB to avoid confusion with similar variants in the DS25BR4xx family. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems that require conversion between CML/LVPECL sources and LVDS destinations at speeds up to 3.125 Gbps. Consider the 40-pin WQFN footprint for board space constraints. Evaluate the need for built-in equalization if trace lengths exceed standard recommendations for passive interconnects.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to the DS25BR440 series of high-speed LVDS buffers. It shares functional similarities with other members of the family but is distinct in its quad-channel configuration and specific pinout arrangement. The NOPB suffix indicates lead-free construction compliant with environmental directives.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct replacements within the same family include DS25BR440TSQ. Verify pin-to-pin compatibility and electrical characteristics against the latest datasheets before substituting any alternative components from different manufacturers.
