DS90UB633ARTVTQ1

Overview

The DS90UB633ARTVTQ1 is an automotive-grade FPD-Link III serializer manufactured by Texas Instruments. It supports 10-bit and 12-bit parallel data inputs with pixel clock frequencies ranging from 56.25 MHz to 100 MHz. The device operates on a single 1.8 V supply for core logic, while the I/O stage accepts 1.8 V, 2.8 V, or 3.3 V levels. It features CML differential outputs for high-speed transmission over coaxial or STP cables up to 15 meters. The component includes four dedicated GPIOs, an I2C-compatible bidirectional control channel, and meets AEC-Q100 Grade 2 standards for operation between -40°C and +105°C.

Feature Summary

• Supports 10-bit and 12-bit payload configurations with programmable data rates up to 100 MHz pixel clock frequency.
• Integrates a continuous low-latency bidirectional control interface channel supporting I2C communication at 400 kHz.
• Utilizes embedded clock technology with DC-balanced coding to enable AC-coupled interconnects over single differential pairs.
• Includes four dedicated General-Purpose Input/Output (GPIO) pins for flexible system configuration and diagnostics.

Applications

• Automotive Surround View Systems (SVS)
• Front Cameras (FC) and Rear View Cameras (RVC)
• Driver Monitor Cameras (DMS)
• Remote satellite RADAR, ToF, and LIDAR sensors
• Security and surveillance systems

Procurement Notes

Verify the specific ordering suffix ARTVTQ1 against the manufacturer's current orderable addendum to confirm package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal performance and moisture sensitivity level for the intended manufacturing process. Cross-reference the datasheet revision history to confirm the document version aligns with the production data status.

Selection Notes

Select this serializer when interfacing image sensors requiring up to 12-bit pixel depth plus synchronization signals to video processors via FPD-Link III. Confirm compatibility with downstream deserializers such as the DS90UB66x-Q1 or DS90UB63x-Q1 series. Evaluate power supply requirements to ensure the 1.8 V core and compatible VDDIO levels meet the system design constraints for noise and stability.

Part Context

This component belongs to the DS90UB633A-Q1 family of FPD-Link III serializers designed for automotive electronic control units. It serves as a bridge between camera imagers and processing modules, simplifying PCB layout by reducing parallel trace skew through serial transmission. The device is part of Texas Instruments' portfolio for advanced driver assistance systems and machine vision applications.

Replacement Considerations

Compatible deserializers include the DS90UB662-Q1 and other devices within the DS90UB63x-Q1 and DS90UB66x-Q1 families. Verify pinout and register compatibility when substituting with other serializers in the DS90UB633A-Q1 series.
