Overview
The DS15BR401TSQ is a four-channel LVDS buffer and repeater manufactured by Texas Instruments, designed for high-speed data transmission applications. It supports data rates up to 2 Gbps 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 within a supply voltage range of 3 V to 3.6 V and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a surface-mount package suitable for automated assembly.
Feature Summary
- Provides four independent channels for buffering and repeating LVDS signals
- Supports multiple input standards including CML, LVDS, and LVPECL
- Features integrated internal termination resistors for simplified design
Applications
- High-speed serial data link buffering
- LVDS signal distribution networks
- Data communication equipment requiring signal integrity maintenance
Procurement Notes
Verify the manufacturer designation as Texas Instruments rather than National Semiconductor, as TI acquired the interface product line. Confirm the specific suffix TSQ indicates automotive qualification (AEC-Q100) if required for the application. Ensure the NOPB variant is considered if lead-free compliance is mandatory. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when four-channel LVDS buffering is required at speeds up to 2 Gbps. It is suitable for designs needing conversion from CML or LVPECL inputs to LVDS outputs. Consider the automotive-grade TSQ suffix if operating in harsh environments. Verify that the power supply constraints fit within the 3 V to 3.6 V range and that the thermal requirements align with the -40°C to +85°C operational window.
Part Context
This part belongs to the DS15BR4xx series of LVDS buffers and repeaters. It shares functional similarities with the DS15BR400 but offers enhanced performance capabilities. The TSQ suffix denotes automotive reliability standards, distinguishing it from commercial grade variants. It serves as a critical interface component for maintaining signal integrity in high-speed digital systems.
Replacement Considerations
The DS15BR400 is a related device within the same family. Verify pin-to-pin compatibility and electrical parameter differences before substitution. Consult the official datasheet for detailed comparison of AC/DC characteristics.
