Overview
The DS90UB949TRGCTQ1 is an HDMI to FPD-Link III bridge serializer manufactured by Texas Instruments. It serializes HDMI v1.4b inputs, supporting video resolutions up to WUXGA (1920x1200) and 1080p60 at 24-bit color depth with a TMDS clock of up to 170MHz. The device features four HDMI inputs and one output channel capable of single or dual FPD-Link III transmission. It operates within a supply voltage range of 1.71V to 1.89V for the core and 3V to 3.6V for I/O, with a data rate of 3.36Gbps. Packaged in a 64-VQFN (9x9mm) with exposed pad, it is qualified under AEC-Q100 for automotive applications and functions across a temperature range of -40°C to +105°C.
Feature Summary
- Supports HDMI v1.4b input modes including DisplayPort++ for high-definition video serialization up to 1080p60.
- Integrates single or dual FPD-Link III outputs to combine video, audio, and bidirectional control data over minimal cabling.
- Includes high-speed reverse channels for GPIO communication and I2C/SPI interfaces for system configuration.
- Features automatic temperature and aging compensation to maintain signal integrity over cable lengths up to 15 meters.
Applications
- Automotive infotainment systems requiring HDMI source connectivity.
- Digital instrument clusters and rear-seat entertainment displays.
- Vehicle camera and sensor interface bridges using FPD-Link III deserializers.
Procurement Notes
Verify the specific ordering suffix to confirm package type and reel specifications. Ensure compatibility with the target FPD-Link III deserializer, such as the DS90UB940-Q1 or DS90UB948-Q1, for proper link establishment. Confirm that the design supports the required power domains and thermal management for the 64-VQFN package.
Selection Notes
Select this component when HDMI input serialization is required for automotive display applications. It is suitable for designs needing support for 1080p60 resolution and integrated audio extraction. Consider backward compatibility with older FPD-Link III deserializers if upgrading existing architectures from DS90UB926Q-Q1 or DS90UB928Q-Q1 based systems.
Part Context
This part belongs to the DS90UB949-Q1 family of HDMI-to-FPD-Link III serializers. It is designed to work in conjunction with compatible deserializers to transmit high-speed video and control signals over shielded twisted pair or coaxial cables. The Q1 suffix indicates automotive qualification, ensuring reliability in harsh vehicle environments.
Replacement Considerations
The DS90UB947TRGCTQ1 is a similar serializer within the same family. Verify pinout and feature parity before substitution, as differences in specific input configurations or auxiliary interfaces may require schematic adjustments.
