DS90UB635TRHBTQ1

Overview

The DS90UB635TRHBTQ1 is a Texas Instruments FPD-Link III serializer designed for automotive applications. It supports a forward channel data rate of 4.16 Gbps and accepts MIPI CSI-2 input with up to four data lanes operating between 600 Mbps and 832 Mbps per lane. The device operates on a single 1.8 V supply (1.71 V to 1.89 V) with a typical power consumption of 0.28 W. It features an ultra-low latency bidirectional control channel at 50 Mbps, supporting I2C and GPIO communication. The component is housed in a 32-pin VQFN package measuring 5 mm x 5 mm and is qualified to AEC-Q100 Grade 2 standards for operation within a temperature range of -40°C to +105°C.

Feature Summary

• Supports high-speed raw data sensors including 2.3MP imagers at 60 fps and 4MP cameras at 30 fps via D-PHY v1.2 and CSI-2 v1.3 interfaces.
• Provides advanced data protection and diagnostic capabilities such as CRC data protection, sensor data integrity checks, and line fault detection.
• Enables precise multi-camera clocking and synchronization when paired with compatible deserializers or hubs.
• Features a unique DIE-ID for counterfeit protection and supports Power-over-Coax (PoC) transmission over coaxial or STP cables.

Applications

• Advanced driver assistance systems (ADAS)
• Surround View Systems (SVS)
• Camera Monitor Systems (CMS)
• Driver Monitoring Systems (DMS)
• Automotive Satellite RADAR Modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the component meets AEC-Q100 Grade 2 requirements for your target environment. Check for moisture sensitivity levels and recommended storage conditions prior to assembly. Ensure compatibility with the intended deserializer models for system integration.

Selection Notes

Select this serializer for applications requiring high-bandwidth transmission from image sensors or radar modules. Ensure the design supports the required 1.8 V power supply and accommodates the 32-pin VQFN footprint. Verify that the cable infrastructure supports either coaxial or shielded twisted pair configurations. Confirm that the downstream processor interface aligns with the supported CSI-2 output formats.
