DS90UB949ATRGCRQ1

Overview

The DS90UB949ATRGCRQ1 is a serializer from the DS90UB949A series, designed as a bridge between HDMI sources and FPD-Link III deserializers. It accepts HDMI v1.4b inputs and serializes video data for transmission over coaxial or STP cables. The device supports up to WUXGA (1920x1200) and 1080p60 resolutions with 24-bit color depth. Key electrical parameters include a maximum power supply voltage of 3.465 V and a minimum of 1.045 V, with operating voltages at 1.1 V, 1.8 V, and 3.3 V. It features six inputs and four outputs, operates within a temperature range of -40°C to +105°C, and consumes approximately 300 mA. The component is housed in a 64-VQFN package and holds AEC-Q100 qualification.

Feature Summary

• Supports HDMI v1.4b input modes including DisplayPort (DP++) passthrough
• Integrates video, audio, and bidirectional control data onto differential pairs
• Includes high-speed reverse channel for GPIO communication up to 2 Mbps
• Features automatic temperature and aging compensation for cable links up to 15 meters

Applications

• Automotive infotainment systems requiring HDMI-to-FPD-Link conversion
• Digital cockpit displays utilizing FPD-Link III architecture
• Vehicle camera and sensor interfaces needing long-reach serial transmission

Procurement Notes

Verify the specific suffix TRGCRQ1 against the official Texas Instruments datasheet to confirm package type and automotive grade compliance. Ensure the ordering information matches the required moisture sensitivity level and reel specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before finalizing procurement.

Selection Notes

Select this serializer when an HDMI source must interface with FPD-Link III deserializers such as the DS90UB940-Q1 or DS90UB948-Q1. It is suitable for designs requiring single-ended coaxial or differential shielded twisted pair cabling. Consider its backward compatibility with earlier DS90UB926Q-Q1 and DS90UB928Q-Q1 devices if legacy integration is necessary.

Part Context

This component belongs to the DS90UB949A family of bridge serializers manufactured by Texas Instruments. It is specifically engineered for automotive applications, adhering to AEC-Q100 standards. The device complements the DS90UH949A series deserializers, forming a complete solution for high-speed video distribution in vehicle networks.

Replacement Considerations

The DS90UB949TRGCTQ1 serves as a verified alternative within the same product family. Both parts share identical functional specifications and automotive qualifications. Verify that the packaging format differences do not impact the existing PCB layout or assembly process.
