DS90UH949ATRGCTQ1

Overview

The DS90UH949ATRGCTQ1 is a 2K HDMI-to-FPD-Link III bridge serializer manufactured by Texas Instruments. It supports video resolutions up to 2560x1600 at 60Hz with 24-bit color depth. The device integrates an HDMI receiver compliant with HDMI 1.4a and HDCP 1.4 specifications, enabling secure content transmission. It features four LVDS output lanes operating at data rates up to 3.675 Gbps per lane for FPD-Link III compatibility. Power supply requirements include 1.045V to 1.89V for the core and 3.0V to 3.6V for I/O. The component operates within a temperature range of -40°C to +105°C and is housed in a 64-pin VQFN package.

Feature Summary

• Integrates HDMI receiver with HDCP 1.4 decryption capabilities for secure video processing
• Supports high-resolution video input up to 2K (2560x1600) at 60Hz with 24-bit color depth
• Converts serialized HDMI data into four parallel LVDS lanes compatible with FPD-Link III deserializers

Applications

• Automotive rear-view camera systems requiring high-definition video transmission
• In-vehicle infotainment displays supporting 2K resolution inputs
• Digital cockpit interfaces utilizing FPD-Link III connectivity

Procurement Notes

Verify the complete part number including the A suffix and Q1 automotive grade designation when sourcing. Confirm the TRGCR packaging variant matches the required reel quantity of 2000 units. Ensure the supplier provides documentation confirming AEC-Q100 qualification status for the specific batch. Cross-reference the manufacturer date code against current production lifecycle notices to avoid obsolete stock.

Selection Notes

Select this component when HDMI input with HDCP support is required for 2K video applications. It serves as the transmitter side of a FPD-Link III link, necessitating a compatible deserializer such as the DS90UH940-Q1 on the display side. Consider power consumption limits and thermal management requirements given the 1.1V and 1.8V dual-supply architecture. Verify that the system design accommodates the 64-VQFN package footprint and exposed pad thermal requirements.

Part Context

This device belongs to the DS90UH949A-Q1 family of bridge serializers designed for automotive display applications. It complements the DS90UB949-Q1, which lacks HDCP support, making this model suitable for protected content scenarios. The series is part of Texas Instruments' broader portfolio of SerDes solutions for vehicle networking. It replaces older generation serializers that did not support 2K resolutions or integrated HDMI reception.

Replacement Considerations

The DS90UH949-Q1 is a non-HDCP version of this device. For pin-compatible alternatives without HDCP, consider the DS90UB949-Q1. Direct replacements with identical functionality are limited within the same family; verify interface compatibility if substituting with other TI serializers.
