DS90C189TWRTDRQ1

Overview

The DS90C189TWRTDRQ1 is a low-power serializer designed for automotive applications, certified to AEC-Q100 standards. It operates on a single 1.8V supply with a maximum data rate of 5.18 Gb/s. The device accepts 24 LVCMOS inputs and converts them into two LVDS output channels featuring a 4D+C interface format. It supports QXGA resolution at 60Hz in single-pixel mode or WUXGA+ resolution in dual-pixel output mode. Operating temperatures range from -40°C to +115°C within a VQFN-64 package.

Feature Summary

• Converts high-color-depth parallel data into a reduced-pin-count LVDS serial stream
• Supports flexible pixel output modes for varying display resolutions
• Engineered for low power consumption in automotive environments

Applications

• Connecting host processors to flat panel displays in vehicles
• Automotive infotainment system video bridges
• Digital cockpit display interfaces

Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package, temperature grade, and tape-and-reel specifications. Confirm AEC-Q100 qualification status matches project requirements. Check humidity sensitivity levels and recommended storage conditions prior to assembly.

Selection Notes

Select this component when interfacing LVCMOS sources with LVDS-compatible FPD-Link displays requiring up to QXGA resolution. Ensure the design accommodates the specific 1.8V power domain and thermal dissipation limits. Verify that the target display controller supports the required 4D+C signaling protocol for proper synchronization.

Part Context

This device belongs to the DS90C189 series of FPD-Link serializers. It serves as a bridge between parallel digital video sources and serial LVDS display interfaces. The Q1 suffix indicates automotive-grade reliability and extended temperature performance suitable for harsh vehicle environments.

Replacement Considerations

Consult official substitution guides for compatible serializers within the DS90C189 family. Verify pinout compatibility and electrical parameter alignment before replacing existing components in established designs.
