Product details
Overview
DS90UB926QSQE/NOPB from Texas Instruments is an AEC-Q100 Grade 2 automotive FPD-Link III deserializer that recovers 24-bit RGB888 video, HS/VS/DE control signals, and synchronized stereo I2S audio from a single AC-coupled STP pair. It operates at 5–85 MHz PCLK, supports 720p resolution, and delivers parallel LVCMOS outputs with adaptive equalization for up to 10-meter cable reach in automotive display systems.
For engineers reviewing the DS90UB926QSQE/NOPB datasheet, DS90UB926QSQE/NOPB pinout, DS90UB926QSQE/NOPB application, or DS90UB926QSQE/NOPB equivalent, key selection criteria include its 60-pin WQFN package, bidirectional I²C-compatible control channel, LOCK status pin for link integrity monitoring, and support for backward compatibility with FPD-Link II interfaces.
Technical Context
The DS90UB926QSQE/NOPB implements an FPD-Link III receiver with embedded clock recovery, adaptive cable equalization, and DC-balanced scrambled data decoding. Its PLL locks to incoming serial streams without training sequences, enabling deterministic lock detection via the dedicated LOCK pin.
It integrates a 31-bit parallel LVCMOS output interface (24-bit RGB + 3 control + 4 I2S audio), configurable GPIOs, and dual power domains (VDD33 and VDDIO) supporting 1.8 V or 3.3 V I/O levels. The device includes BIST mode, spread-spectrum clocking (SSCG), and EMI-reduction features like enhanced progressive turn-on (EPTO).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCLK Range | 5–85 MHz - defines supported video timing resolution from WVGA to 720p with pixel-level synchronization |
| Color Depth | 24-bit RGB888 - enables full-color display fidelity without dithering artifacts in native mode |
| Cable Reach | Up to 10 meters over AC-coupled STP - eliminates need for active repeaters in mid-range automotive displays |
| Supply Voltage | VDD33: 3.0–3.6 V; VDDIO: 1.71–1.89 V or 3.0–3.6 V - enables flexible I/O voltage selection for host processor interfacing |
| ESD Rating | HBM ±8 kV, CDM ±1.25 kV - meets AEC-Q100 Grade 2 requirements for under-hood and cabin environments |
| Operating Temp | −40°C to +105°C ambient - qualified for automotive display modules in instrument clusters and center consoles |
| Power Down Current | VDD33: 2–10 mA, VDDIO: 0.05–10 mA - enables ultra-low-power sleep states during display blanking or system standby |
Pinout & Package
DS90UB926QSQE/NOPB uses a 60-pin WQFN (NKB) package with 9.0 mm × 9.0 mm body size and exposed thermal pad (DAP) requiring ≥9 vias to GND for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN+, RIN− | FPD-Link III differential input | AC-coupled LVDS inputs accepting serialized video/audio/control; require 0.1 µF series capacitors |
| ROUT[23:0] | Parallel RGB output bus | 24-bit LVCMOS outputs (R[7:0]/G[7:0]/B[7:0]) with pulldown bias; tri-state when PDB = L |
| HS, VS, DE, PCLK | Video timing control outputs | LVCMOS outputs synchronized to recovered pixel clock; pulse-width constraints apply per control filter setting |
| I2S_CLK, I2S_WC, I2S_DA | Stereo audio interface outputs | LVCMOS outputs for I2S bit clock, word clock, and data; optionally configurable as GPO_REG[8:6] |
| SCL, SDA | I²C control interface | Open-drain bidirectional bus for configuration and status readback; requires external 4.7 kΩ pullups to VDD33 |
| LOCK, PASS | Link status indicators | LOCK = high indicates stable PLL lock; PASS = high confirms error-free payload reception |
| PDB, OEN | Power and output control | PDB = low forces full power-down (PLL off, outputs tri-state); OEN enables/disables all LVCMOS outputs |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional I²C control channel | Enables real-time register access and status monitoring over same physical link used for video transport |
| Adaptive cable equalization | Compensates for frequency-dependent loss in long STP cables without manual tuning or external components |
| Embedded clock recovery | Eliminates need for separate clock trace or reference oscillator; lock detection via dedicated LOCK pin |
| Image enhancement engine | Provides white balance adjustment and dithering to improve visual quality on lower-bit-depth panels |
| EMI reduction (SSCG + EPTO) | Reduces peak radiated emissions by spreading spectrum and controlling edge rates of LVCMOS outputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link III deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB926Q-Q1 | Identical silicon; Q1 suffix denotes full AEC-Q100 Grade 2 qualification including extended temperature and ESD testing | Required for safety-critical automotive production; DS90UB926QSQE/NOPB is commercial-grade variant | Select DS90UB926Q-Q1 for production automotive programs; DS90UB926QSQE/NOPB suits prototyping and non-automotive industrial use |
| DS90UB954QSQE/NOPB | Higher bandwidth (up to 108 MHz), supports 1080p60 and additional audio channels; larger 80-pin WQFN package | Targeted at premium ADAS displays and digital cockpits requiring higher resolution and multi-channel audio | Choose DS90UB954QSQE/NOPB only if 720p is insufficient; migration requires PCB layout change due to pin count and package size |
Compared with DS90UB926Q-Q1, the DS90UB926QSQE/NOPB offers identical functionality but lacks full automotive qualification-making it suitable for development and non-safety applications. Versus DS90UB954QSQE/NOPB, it provides optimal cost and footprint for 720p systems without over-engineering.

FAQ
What is the primary function of the DS90UB926QSQE/NOPB in an automotive video system?
The DS90UB926QSQE/NOPB functions as an FPD-Link III deserializer that converts a high-speed serialized video/audio/control stream from a single differential pair into parallel 24-bit RGB888 video, HS/VS/DE timing signals, and stereo I2S audio. It enables compact, EMI-robust cabling between ECUs and displays while maintaining precise timing alignment required for automotive applications.
Does the DS90UB926QSQE/NOPB support backward compatibility with FPD-Link II interfaces?
Yes, the DS90UB926QSQE/NOPB supports backward compatibility with FPD-Link II serializers. This allows integration with legacy camera or display modules without redesigning the physical layer, though some advanced features like bidirectional control and adaptive equalization remain disabled in compatibility mode.
How does the LOCK pin on the DS90UB926QSQE/NOPB indicate link status?
The LOCK pin on the DS90UB926QSQE/NOPB outputs a logic high when the internal PLL achieves stable lock to the incoming serial data stream, and logic low when unlocked. Unlike protocols requiring training sequences, this detection is deterministic and occurs without special SYNC patterns, enabling immediate link health verification in safety-critical systems.
Can the DS90UB926QSQE/NOPB operate with both 1.8 V and 3.3 V LVCMOS I/O levels?
Yes, the DS90UB926QSQE/NOPB supports dual I/O voltage operation: VDDIO may be set to either 1.8 V ±5% or 3.0–3.6 V, allowing direct interfacing with host processors or display controllers using either voltage standard without level-shifting circuitry.
What is the role of the PASS output pin on the DS90UB926QSQE/NOPB?
The PASS output pin on the DS90UB926QSQE/NOPB signals error-free payload reception: it asserts high when no bit errors are detected in the decoded video/audio/control data, and low when one or more errors occur. This provides real-time link integrity feedback for diagnostic and fail-safe display management in automotive systems.
