Product details
Overview
DS90UB913QSQX/NOPB from Texas Instruments is an automotive-grade FPD-Link III serializer for camera interface applications, converting 10- or 12-bit parallel video data (with HSYNC/VSYNC) into a single high-speed differential stream at up to 100 MHz pixel clock, supporting up to 25 m shielded twisted-pair cable, and featuring bidirectional I²C-compatible control channel with 400 kHz support.
For engineers reviewing the DS90UB913QSQX/NOPB datasheet, DS90UB913QSQX/NOPB pinout, DS90UB913QSQX/NOPB application, or DS90UB913QSQX/NOPB equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive AEC-Q100 Grade 2 qualification, exact WQFN-32 package mapping, and two rigorously cross-checked alternative parts for front/rear-view camera ECU designs.
Technical Context
The DS90UB913QSQX/NOPB implements embedded-clock DC-balanced encoding for AC-coupled interconnects, enabling full-duplex bidirectional control channel operation independent of video blanking. Its CML-based DOUT+/DOUT− outputs drive a single differential pair while maintaining low latency and jitter performance across temperature (−40°C to +105°C).
It integrates adaptive equalization-ready receiver inputs on the companion deserializer side (DS90UB914Q-Q1), supports dual-imager selection via SEL input, and provides four programmable GPOs-two configurable as CLKOUT/CLKIN for external oscillator mode-enabling flexible timing architecture in surround-view and collision mitigation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCLK Range | 10–100 MHz: supports 10-bit payloads up to 100 MHz or 12-bit payloads up to 75 MHz for megapixel imager interfacing. |
| Interface Standard | FPD-Link III compliant: enables single differential pair transmission with embedded clock and DC-balanced coding for AC coupling. |
| Control Channel | Bidirectional I²C-compatible bus at 400 kHz: allows real-time register access and configuration without interrupting video stream. |
| Power Supply | 1.8 V core (±5%), 1.8/2.8/3.3 V I/O: supports mixed-voltage system integration with LVCMOS-compatible DIN/GPO pins. |
| Automotive Qualification | AEC-Q100 Grade 2: qualified for −40°C to +105°C ambient operation, meeting ISO 10605 and IEC 61000-4-2 ESD requirements. |
| Package | 32-pin WQFN (5.0 mm × 5.0 mm): compact footprint optimized for space-constrained ECU PCB layouts near camera modules. |
| ESD Robustness | ≥±25 kV air discharge on CML I/O: ensures reliability in harsh automotive environments with high-voltage transients. |
Pinout & Package
DS90UB913QSQX/NOPB uses a 32-pin WQFN package (5.0 mm × 5.0 mm) with exposed thermal pad (DAP) requiring ≥9 vias to ground plane. Pin functions are validated per TI SNLS420D Rev D datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DIN[0:11] | LvCMOS parallel data input | Accepts 10- or 12-bit pixel data plus sync signals; pulldown-enabled for robust idle-state termination. |
| PCLK, HSYNC, VSYNC | LvCMOS timing inputs | Sampled on rising edge (configurable via TRFB); defines video frame structure and pixel rate alignment. |
| GPO[0:3] | Programmable general-purpose output | GPO[2] doubles as CLKOUT; GPO[3] as CLKIN-enables external oscillator synchronization and GPIO feedback. |
| SCL/SDA | I²C bidirectional control bus | Open-drain with external pullups to VDDIO; supports 400 kHz control traffic concurrent with video transport. |
| DOUT+/DOUT− | CML differential serial output | AC-coupled (100 nF) high-speed forward channel driving FPD-Link III interconnect; 340 mV typical differential swing. |
| MODE, PDB, ID[x] | Configuration & control | MODE selects PCLK source (imager vs. external oscillator); PDB enables power-down; ID[x] sets I²C slave address. |
Key Features
| Feature | Design Value |
|---|---|
| DC-balanced encoding | Enables AC-coupled STP interconnects without baseline wander, eliminating DC-blocking capacitor sizing uncertainty. |
| Embedded clock architecture | Removes skew between parallel data and clock paths, simplifying PCB routing and reducing layer count in ECU designs. |
| Adaptive equalization support | Compensates for up to 25 m STP loss on deserializer side (DS90UB914Q-Q1), extending reach without active repeaters. |
| AT-speed BIST & LOCK reporting | LOCK pin indicates PLL lock status; BISTEN/PASS pins enable in-system link integrity validation during production test. |
| EMI/EMC mitigation | Programmable spread-spectrum clock generation (SSCG) and staggered outputs reduce peak radiated emissions in vehicle cabins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link III serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB913AQSQX/NOPB | Supports coax or STP media; higher minimum PCLK (25 MHz) and no 10–20 MHz range. | Targeted for longer-reach or higher-noise environments where coax shielding is preferred over STP. | Select when cable length exceeds 25 m or EMI environment demands coaxial shielding. |
| DS90UB953TRGCRQ1 | Higher bandwidth (1.5 Gbps), integrated HDCP, 4-lane MIPI CSI-2 output instead of parallel LVCMOS. | Designed for next-gen ADAS SoCs with native MIPI CSI-2 input; requires different host-side interface logic. | Choose for new designs targeting MIPI-native processors; not drop-in compatible with DS90UB913QSQX/NOPB parallel interface. |
Compared with DS90UB913AQSQX/NOPB, DS90UB913QSQX/NOPB offers broader low-frequency support (10–100 MHz) ideal for legacy imager integration; versus DS90UB953TRGCRQ1, it retains simple LVCMOS parallel interfacing but lacks MIPI output and HDCP, making it optimal for cost-sensitive, non-encrypted camera links.

Yes, DS90UB913QSQX/NOPB supports 1.8 V, 2.8 V, and 3.3 V LVCMOS I/O levels on its DIN, GPO, and control pins. VDDIO must be set accordingly, and DC specifications (VIH/VIL/VOH/VOL) are guaranteed per voltage rail per SNLS420D Section 8.5.
How does the bidirectional control channel function in DS90UB913QSQX/NOPB?
The DS90UB913QSQX/NOPB implements a full-duplex I²C-compatible bidirectional control channel over the same differential pair used for video.
