Product details
Overview
DS90UB953TRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive FPD-Link III serializer that converts MIPI CSI-2 input (up to 4 lanes × 832 Mbps) into a 4.16 Gbps forward channel over coax or STP, supporting 2.3MP/60fps image sensors and RADAR/LiDAR in ADAS camera modules. It integrates ultra-low-latency bidirectional I²C control (50 Mbps), Power-over-Coax (PoC), and precision multi-sensor synchronization.
For engineers reviewing the DS90UB953TRHBRQ1 datasheet, DS90UB953TRHBRQ1 pinout, DS90UB953TRHBRQ1 application, or DS90UB953TRHBRQ1 equivalent, key selection criteria include CSI-2 lane count support, PoC compatibility, AEC-Q100 Grade 2 thermal range (–40°C to +105°C), VQFN-32 package constraints, and functional safety documentation for ISO 26262 ASIL-B system integration.
Technical Context
The DS90UB953TRHBRQ1 implements a D-PHY v1.2 receiver with configurable 1/2/4-lane CSI-2 input and a CDR-based FPD-Link III transmitter delivering 4.16 Gbps forward data plus embedded 50 Mbps bidirectional control. Its clock architecture supports synchronous mode (with external CLKIN) or non-synchronous internal clocking (24.2–25.5 MHz reference).
It features integrated voltage/temperature sensing on GPIO[1:0], programmable alarm thresholds, CRC data protection, line fault detection, and I²C write protection - all designed for fail-operational ADAS sensor links requiring deterministic latency and diagnostic coverage.
Key Specifications

The DS90UB953TRHBRQ1 supports up to 832 Mbps per CSI-2 lane in high-speed mode, compliant with D-PHY v1.2. This enables full utilization of its 4.16 Gbps forward channel when operating in 4-lane configuration, sufficient for 2.3MP image sensors running at 60 fps. The device also supports 1- and 2-lane modes for lower-resolution or cost-optimized implementations.
Does DS90UB953TRHBRQ1 support Power-over-Coax (PoC) operation?
Yes, DS90UB953TRHBRQ1 is explicitly designed for Power-over-Coax compatibility. It operates with AC-coupled DOUT+/− outputs and supports bias-T injection of DC power onto the same coaxial cable used for high-speed data and bidirectional control, eliminating separate power lines in compact camera modules.
What is the operating temperature range for DS90UB953TRHBRQ1?
DS90UB953TRHBRQ1 is AEC-Q100 Grade 2 qualified with an ambient operating temperature range of –40°C to +105°C. This specification is validated across all electrical parameters and ensures reliable operation in exterior automotive locations including front grilles, side mirrors, and rear bumpers.
