DS15BR400TSQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS15BR400TSQ/NOPB is a quadruple LVDS buffer and repeater manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 2 Gb/s with an operating supply voltage range of 3 V to 3.6 V, typically powered at 3.3 V. The device features four drivers and four receivers, accepting CML, LVDS, or LVPECL input signals and converting them to LVDS outputs. It operates within a temperature range of -40°C to +85°C and is housed in a TQFP-48 surface-mount package. The typical propagation delay is 2 ns, and the quiescent current is approximately 215 mA.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides signal buffering and repeating capabilities for low-voltage differential signaling (LVDS) applications.
• Accepts multiple input standards including CML, LVDS, and LVPECL for flexible system integration.
• Converts various input logic levels to standardized LVDS outputs to maintain signal integrity over long traces.

Signal Buffers, Repeaters, Splitters Applications

• High-speed digital video interfaces requiring signal regeneration.
• Data communication systems utilizing LVDS protocols.
• Industrial control networks needing robust differential signaling.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix TSQ against official Texas Instruments documentation to confirm automotive qualification status, as standard commercial variants may differ. Ensure the NOPB designation confirms lead-free and RoHS compliance prior to ordering. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components. Confirm package type matches the design footprint requirements.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a quad-channel LVDS driver/receiver is required for 2 Gb/s applications. It is suitable for designs needing compatibility with CML, LVDS, or LVPECL inputs. Consider the TQFP-48 package constraints and thermal dissipation characteristics during PCB layout. Verify that the 3.3 V power supply aligns with the system's voltage domain specifications.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS15BR400 series of LVDS interface integrated circuits from Texas Instruments. It is functionally related to other devices in the family such as the DS15BR400TVSX/NOPB, which shares similar electrical characteristics but may differ in packaging or qualification. The series is designed to support high-speed data transmission needs in complex electronic systems.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS15BR400TVSX/NOPB is a comparable variant within the same product family. Verify if the TVSX suffix indicates a different package or qualification level compared to the TSQ suffix before substitution. Consult official datasheets to ensure pinout and electrical parameter compatibility.
