DS90UB934TRGZRQ1

Overview

The DS90UB934TRGZRQ1 is an automotive-grade FPD-Link III deserializer designed for high-resolution camera applications. It supports 12-bit parallel CMOS outputs at frequencies up to 100 MHz, enabling video resolutions of 1MP at 60fps and 2MP at 30fps. The device operates within a temperature range of -40°C to +105°C and complies with AEC-Q100 Grade 2 standards. Packaged in a 48-pin VQFN (7x7 mm) format, it integrates adaptive equalization to compensate for cable degradation without external programming.

Feature Summary

• Adaptive equalization technology automatically compensates for cable aging and signal degradation across various cable types and lengths.
• Ultra-low latency bidirectional control data channel ensures precise synchronization between the serializer and deserializer.
• Integrated cable link detection diagnostics provide real-time monitoring of physical layer integrity.
• Supports Power over Cable (PoC) operation mode to simplify wiring harness design.

Applications

• Automotive rear-view camera systems
• Surround view monitoring (SVM) systems
• Advanced Driver Assistance Systems (ADAS)
• Satellite radar imaging interfaces

Procurement Notes

Verify the component against official Texas Instruments datasheets to confirm AEC-Q100 qualification status and package markings. Ensure compatibility with upstream serializers such as the DS90UB913A or DS90UB933. Validate that the supply chain provides genuine parts with correct date codes and lot numbers to meet automotive quality requirements.

Selection Notes

Select this model when designing systems requiring 1MP/60fps or 2MP/30fps resolution via FPD-Link III. It serves as a direct upgrade path from legacy devices like the DS90UB914A-Q1 due to higher bandwidth capabilities. Ensure the host image sensor supports 12-bit parallel CMOS output at 100 MHz to fully utilize the deserializer's performance specifications.

Part Context

This component belongs to the DS90UB934-Q1 series of FPD-Link III deserializers. It is specifically engineered for automotive environments, offering enhanced reliability compared to non-automotive counterparts. The part number suffix 'RZ' indicates the specific tape-and-reel packaging configuration used for surface-mount assembly.

Replacement Considerations

The DS90UB914A-Q1 is a documented predecessor in the same family. Migration guides are available for transitioning designs from older parallel-output deserializers to this model while maintaining backward compatibility modes where applicable.
