Product details
Overview
DS90UB926QSQX/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 link. 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 DS90UB926QSQX/NOPB datasheet, DS90UB926QSQX/NOPB pinout, DS90UB926QSQX/NOPB application, or DS90UB926QSQX/NOPB equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade operating conditions (−40°C to +105°C), real-world timing constraints, and direct alternative options for display interface design.
Technical Context
The DS90UB926QSQX/NOPB implements a full-duplex FPD-Link III receiver with embedded clock recovery, adaptive cable equalization, and DC-balanced scrambled serial data decoding. It reconstructs 31-bit parallel output (24-bit RGB + 3 control + 4 I2S audio) without training sequences, using a dedicated LOCK pin for real-time link status indication.
It integrates bidirectional I²C-compatible control channel, image enhancement (white balance, dithering), SSCG and EPTO for EMI reduction, and low-power modes including sleep and power-down states controlled by PDB and OSS_SEL pins. The device supports backward compatibility with FPD-Link II and repeater functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCLK Range | 5–85 MHz - defines supported video pixel clock rates for 720p and lower resolutions |
| Color Depth | 24-bit RGB888 - enables full-color HD display output with separate R[7:0], G[7:0], B[7:0] LVCMOS buses |
| Video Interface | FPD-Link III (AC-coupled STP) - single-pair differential serial input supporting up to 10 m cable length |
| Operating Temp | −40°C to +105°C - AEC-Q100 Grade 2 qualification for under-hood and dashboard automotive environments |
| I/O Voltage | 1.8 V or 3.3 V LVCMOS - configurable VDDIO allows interoperability with diverse host processor I/O domains |
| Audio Support | Stereo I2S with MCLK, I2S_CLK, I2S_WC, I2S_DA, I2S_DB - synchronous audio transport alongside video |
| Power Modes | Active / Sleep / Power-down - IDDZ ≤10 mA (VDD33) and IDDIOZ ≤10 mA (VDDIO) in PDB = L state |
Pinout & Package
DS90UB926QSQX/NOPB uses a 60-pin WQFN package (9.0 mm × 9.0 mm) with exposed thermal pad (DAP = GND). Pin functions are validated per TI SNLS422D datasheet Rev D (August 2017).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN+, RIN− | FPD-Link III differential input | AC-coupled LVDS receiver inputs accepting serialized stream from DS90UB925Q; require 0.1 µF coupling caps |
| ROUT[23:0] | Parallel LVCMOS video/audio output | 31-bit bus: R[7:0]/G[7:0]/B[7:0] + HS/VS/DE + I2S_CLK/WC/DA/DB - all with pulldown-enabled LVCMOS drivers |
| PCLK, HS, VS, DE | Timing control outputs | Pixel clock and video sync signals synchronized to recovered data; pulse width constraints apply per control filter mode |
| SCL, SDA | I²C control interface | Open-drain bidirectional bus (3.3 V only) for configuration register access and device addressing via IDx pin |
| LOCK, PASS | Status monitoring outputs | LOCK = high indicates stable PLL lock; PASS = high confirms error-free payload reception - both LVCMOS with pulldown |
| PDB, OEN, OSS_SEL | Power/control inputs | PDB controls enable/disable; OEN gates LVCMOS outputs; OSS_SEL selects sleep-state behavior of outputs during low-power mode |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Cable Equalization | Compensates for frequency-dependent loss in long STP cables up to 10 meters, maintaining signal integrity without manual tuning |
| Bidirectional I²C Control Channel | Enables host-side configuration and status readback over same physical link used for video/audio - no extra wires required |
| Embedded Clock Recovery | Eliminates need for separate clock trace; recovers timing directly from serial stream, removing skew and jitter accumulation |
| EMI Reduction (SSCG + EPTO) | Spread-spectrum clocking (±0.5–2.5% deviation) and enhanced progressive turn-on minimize radiated emissions in sensitive automotive RF environments |
| Image Enhancement Engine | On-chip white balance adjustment and dithering improve color fidelity and reduce banding on 6- or 8-bit display panels |

FAQ
What is the primary function of the DS90UB926QSQX/NOPB in an automotive display system?
The DS90UB926QSQX/NOPB serves as an FPD-Link III deserializer that converts a high-speed serialized video/audio stream from a single differential pair into parallel 24-bit RGB888, HS/VS/DE control signals, and stereo I2S audio. In automotive systems, it enables compact, EMI-robust cabling between graphics processors or camera modules and display controllers while maintaining precise timing and AEC-Q100 reliability for DS90UB926QSQX/NOPB deployments.
Does the DS90UB926QSQX/NOPB support both 1.8 V and 3.3 V LVCMOS I/O interfaces?
Yes, the DS90UB926QSQX/NOPB supports dual-voltage LVCMOS I/O operation via its VDDIO supply pin, which accepts either 1.8 V ±5% or 3.3 V (3.0–3.6 V). All parallel outputs - including ROUT[23:0], PCLK, HS, VS, DE, and I2S signals - are compatible with either voltage domain, allowing seamless integration with mixed-voltage host processors and display drivers in DS90UB926QSQX/NOPB-based designs.
How does the LOCK pin on the DS90UB926QSQX/NOPB indicate link status?
The LOCK pin on the DS90UB926QSQX/NOPB provides real-time indication of PLL lock status: it asserts high when the internal PLL has successfully recovered a stable clock from the incoming FPD-Link III serial stream, and goes low when unlocked. This occurs without requiring training sequences or SYNC patterns, making DS90UB926QSQX/NOPB suitable for fast-boot automotive displays where immediate link validation is critical.
Can the DS90UB926QSQX/NOPB be used in non-automotive applications?
While the DS90UB926QSQX/NOPB meets AEC-Q100 Grade 2 specifications (−40°C to +105°C), its core FPD-Link III deserialization functionality is not restricted to automotive use. It can be deployed in industrial HMIs, medical displays, or avionics systems requiring robust serial video transport - provided thermal, ESD, and reliability requirements align. However, DS90UB926QSQX/NOPB's qualification and characterization are optimized for automotive environments.
What is the maximum supported cable length for the DS90UB926QSQX/NOPB with STP interconnect?
The DS90UB926QSQX/NOPB supports AC-coupled shielded twisted-pair (STP) interconnect up to 10 meters, enabled by its adaptive equalizer that compensates for frequency-dependent attenuation in long cables. Performance depends on cable quality and PCLK frequency - full 10-meter reach is validated at 720p (85 MHz PCLK) with standard 100-Ω STP per TI SNLS422D datasheet, confirming DS90UB926QSQX/NOPB's suitability for distributed automotive display architectures.
