SN75DP149RSBT

Overview

The SN75DP149RSBT is a video retimer IC designed to convert DisplayPort++ 1.1 signals to HDMI 1.4b outputs. It operates at data rates up to 3.4 Gbps per lane. The device supports I2C configuration and includes built-in equalization for signal integrity. It functions within an ambient temperature range of 0°C to +70°C. The component is housed in a 40-pin WQFN package measuring 5x5 mm with an exposed pad for thermal management.

Feature Summary

• Converts DisplayPort++ 1.1 input signals to HDMI 1.4b compliant output formats
• Provides signal retiming and equalization to maintain integrity at high data rates
• Supports I2C interface for dynamic configuration and control
• Operates reliably across standard commercial temperature ranges

Applications

• DisplayPort to HDMI adapters and dongles
• Video distribution systems requiring signal regeneration
• Consumer electronics with mixed display interface requirements
• Industrial monitoring equipment needing reliable video transmission

Procurement Notes

Verify the specific suffix 'RSBT' confirms the 40-WQFN package and commercial temperature grade. Confirm I2C address settings match system design requirements. Ensure PCB layout accommodates the 5x5 mm footprint and thermal pad connections. Validate supply chain authenticity through authorized Texas Instruments channels or certified distributors.

Selection Notes

Select this component when converting DP++ sources to HDMI sinks is required. Choose based on the 3.4 Gbps bandwidth limit for single-link HD content. Consider the WQFN package for space-constrained designs. Verify compatibility with downstream HDMI receiver specifications. Evaluate thermal performance under continuous operation conditions.

Part Context

This part belongs to the SNx5DP149 family of video retimers from Texas Instruments. It complements other interface solutions like the SN75DP159 for higher bandwidth applications. The series addresses the growing need for seamless conversion between digital display standards in modern multimedia devices.

Replacement Considerations

Public confirmed substitute: SN75DP149RSBR (Reel packaging variant). Verify pinout and electrical characteristics remain identical before substitution.
