DS90UB914ATRHSJQ1

Overview

The DS90UB914ATRHSJQ1 is an automotive-grade FPD-Link III deserializer manufactured by Texas Instruments. It operates within a supply voltage range of 1.71 V to 3.6 V and supports data rates up to 1.4 Gbps. The device features one LVDS input and twelve LVCMOS outputs, packaged in a 48-WQFN (7x7 mm) format. It is qualified under AEC-Q100 standards for Grade 2, ensuring reliability in harsh environments with an operating temperature range from -40°C to +105°C. The component includes a low-latency bidirectional control channel for I2C communication.

Feature Summary

• Supports 10-bit or 12-bit pixel depth video data transmission over a single coaxial cable or differential pair
• Integrates a multiplexer allowing selection between two input imagers with only one active at a time
• Provides independent low-latency bidirectional control channel for I2C port information transfer

Applications

• Connection between image sensors and video processors in Electronic Control Units (ECUs)
• Automotive camera systems requiring high-speed video and control signals
• Video data interfaces driving up to 12-bit pixel depth with synchronous signals

Procurement Notes

Verify the complete part number including suffixes such as ATRHSJQ1 to ensure correct package, temperature grade, and automotive qualification. Confirm that the source document explicitly identifies the manufacturer as Texas Instruments. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when interfacing FPD-Link III serializers with parallel output deserializers in automotive ECU applications. Ensure the system requires a single input to multiple parallel outputs configuration. Verify compatibility with 10/12-bit data widths and check if the specific WQFN-48 package fits the PCB layout constraints.

Part Context

This device belongs to the DS90UB914A series of FPD-Link III deserializers. It is designed specifically for automotive imaging applications where reliable, high-speed data transmission is critical. The Q1 suffix indicates its qualification for automotive use according to AEC-Q100 standards, distinguishing it from non-automotive variants.

Replacement Considerations

The DS90UB914QSQ/NOPB is a listed alternative for the DS90UB914 series. Verify pinout compatibility and electrical specifications before substitution. Note that packaging and suffix variations may affect mechanical fit and thermal performance.
