DS15BR401TVS/NOPB

Overview

The DS15BR401TVS/NOPB is a four-channel LVDS buffer and repeater manufactured by Texas Instruments. It supports data rates up to 2 Gb/s with low jitter characteristics from DC to the maximum speed. The device accepts CML, LVDS, or LVPECL input signals and converts them to LVDS outputs. It operates on a single 3.3 V power supply with a minimum voltage of 3 V and a maximum of 3.6 V. The component features an integrated 100 Ω output termination resistor and requires external 100 Ω input termination. It is housed in a 48-pin TQFP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Four-channel LVDS buffering and signal repeating capability for high-speed data transmission
• Supports multiple input standards including CML, LVDS, and LVPECL
• Integrated 100 Ω output termination resistor to simplify PCB layout
• Low jitter performance across the full operating frequency range

Applications

• High-speed serial data distribution networks
• Clock distribution systems requiring low skew
• Video and display interface applications
• Telecommunications equipment signal conditioning

Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired by TI. Confirm the specific suffix NOPB indicates lead-free and RoHS compliance. Ensure the TQFP-48 package matches the design requirements. Check for moisture sensitivity levels if the component has been exposed to ambient conditions prior to assembly.

Selection Notes

Select this component when interfacing between different logic families such as CML sources and LVDS loads. The integrated output termination reduces component count compared to discrete solutions. Ensure the system power supply remains within the 3.0 V to 3.6 V range to maintain specified electrical parameters and timing accuracy.

Part Context

This part belongs to the DS15BR401 series of high-speed interface ICs. It serves as a bridge for signal integrity in dense electronic systems. The TVS/NOPB variant specifies the thermal vias solderable version with no lead-based materials. It is distinct from automotive-grade variants which carry the TSQ suffix.

Replacement Considerations

The DS15BR400 is a related device within the same family offering similar functionality. Verify pin compatibility and electrical specifications before substitution. Automotive versions like the DS15BR401TSQ/NOPB offer extended reliability but may have different qualification standards.
