Product details
Overview
DS90UR905QSQE/NOPB from Texas Instruments is an automotive-grade FPD-Link II serializer IC that converts 24-bit RGB888 video with HS/VS/DE control signals into a single-pair AC-coupled differential serial stream. It supports pixel clock frequencies from 5 MHz to 65 MHz (140 Mbps–1.82 Gbps), integrates programmable de-emphasis and VOD selection, and operates across –40°C to +105°C for in-vehicle display links.
For engineers reviewing the DS90UR905QSQE/NOPB datasheet, DS90UR905QSQE/NOPB pinout, DS90UR905QSQE/NOPB application, or DS90UR905QSQE/NOPB equivalent, key selection criteria include PCLK range compatibility, LVCMOS I/O voltage flexibility (1.8 V or 3.3 V), AEC-Q100 Grade 2 qualification, integrated termination, and BIST-enabled link validation capability.
Technical Context
The DS90UR905QSQE/NOPB implements a DC-balanced scrambler to enable AC-coupled STP cable runs up to 10 meters, with selectable output VOD (±280 mV or ±420 mV) and pin- or register-controlled de-emphasis for channel loss compensation. Its PLL embeds the PCLK into the serial stream without requiring a reference clock at the deserializer end.
It features dual-mode configuration via CONFIG[1:0] pins - supporting interoperability with DS90UR906Q-Q1 (with optional control-signal filtering) or legacy devices like DS90UR124 and DS90C124. Power-down mode (PDB = 0) shuts down the PLL and forces DOUT± high, minimizing IDD to microamp levels.
Key Specifications

|---|---|
| PCLK Range | 5–65 MHz - enables QVGA to XGA resolution support with real-time video streaming over FPD-Link II |
| Data Rate | 140 Mbps to 1.82 Gbps - determines maximum color depth and frame rate achievable on single twisted pair |
| Supply Voltage (VDDIO) | 1.8 V ±5% or 3.3 V ±10% - allows direct interfacing with both low-voltage graphics processors and legacy 3.3-V controllers |
| Output VOD | Selectable ±280 mV or ±420 mV - adjusts driver strength for optimal signal integrity across varying cable lengths and losses |
| Operating Temperature | –40°C to +105°C - meets AEC-Q100 Grade 2 requirements for under-hood and dashboard display systems |
| ESD Rating | >8-kV HBM, ISO 10605 compliant - ensures robustness in automotive assembly and field environments |

Pinout & Package
DS90UR905QSQE/NOPB uses a 48-pin WQFN package (7.0 mm × 7.0 mm) with exposed thermal pad (DAP) requiring ≥9 vias to ground plane. Pin functions are validated per TI SNLS313I Rev I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| R[7:0], G[7:0], B[7:0] | Parallel RGB data inputs | 24-bit LVCMOS inputs with internal pulldowns; accept RGB888 format synchronized to PCLK edge selected by RFB |
| HS / VS / DE | Video timing control inputs | LVCMOS inputs with pulse-width constraints (≥3 PCLKs for HS/DE; ≥130 PCLKs for VS) when filter enabled |
| PCLK | Pixel clock input | Latches parallel data on rising/falling edge per RFB strap; defines serial data rate and video bandwidth |
| DOUT+/DOUT− | FPD-Link II differential outputs | LVDS outputs requiring 100-nF AC coupling; transmit scrambled, DC-balanced serial stream over STP |
| PDB | Power-down control | Active-low input; forces PLL shutdown and high-Z DOUT± when asserted, reducing supply current to µA range |
| VODSEL / De-Emph / CONFIG[1:0] | Configuration strapping | Set VOD level, enable de-emphasis, and select interop mode (e.g., CONFIG[1:0]=00 → DS90UR906Q-Q1, no filter) |

FAQ
What is the primary function of DS90UR905QSQE/NOPB in an automotive display system?
The DS90UR905QSQE/NOPB acts as an FPD-Link II serializer, converting parallel RGB888 video data with HS/VS/DE timing signals into a high-speed, AC-coupled differential serial stream for transmission over a single twisted-pair cable. It enables compact, EMI-robust connections between graphics processors and displays in vehicles, supporting resolutions from QVGA to XGA at pixel clocks up to 65 MHz.
Does DS90UR905QSQE/NOPB require an external reference clock at the deserializer end?
No, DS90UR905QSQE/NOPB does not require an external reference clock at the deserializer end. Its embedded PLL recovers the pixel clock from the serial data stream, allowing the companion DS90UR906Q-Q1 deserializer to lock rapidly without training sequences or external timing sources - a key advantage for automotive startup timing and reliability.
How is the output voltage swing (VOD) configured on DS90UR905QSQE/NOPB?
The output voltage swing of DS90UR905QSQE/NOPB is configured via the VODSEL pin: logic high selects ±420 mV (840 mVp-p) for longer cables or de-emphasis use, while logic low selects ±280 mV (560 mVp-p) for shorter interconnects. This setting can also be controlled dynamically via I²C register access, providing flexibility in system tuning.
Can DS90UR905QSQE/NOPB interface directly with a 3.3-V graphics processor?
Yes, DS90UR905QSQE/NOPB supports 3.3-V LVCMOS I/O through its VDDIO supply rail (rated 3.3 V ±10%). When VDDIO is set to 3.3 V, all parallel interface pins (R[7:0], G[7:0], B[7:0], HS, VS, DE, PCLK, etc.) operate at 3.3-V logic levels, enabling direct connection to 3.3-V host processors without level-shifting circuitry.
What is the role of the BISTEN pin on DS90UR905QSQE/NOPB?
The BISTEN pin on DS90UR905QSQE/NOPB enables built-in self-test mode: when asserted high, it activates pseudorandom pattern generation and transmission for link integrity verification. The corresponding DS90UR906Q-Q1 deserializer reports pass/fail status on its PASS pin, allowing automated production testing of the full FPD-Link II channel without external test equipment.
