DS90UB948TNKDTQ1

Overview

The DS90UB948TNKDTQ1 is a dual-channel FPD-Link III deserializer certified to AEC-Q100 Grade 2 standards, supporting an operating temperature range of -40°C to +105°C. It converts single or dual channel FPD-Link III streams into OpenLDI (LVDS) formats, supporting video resolutions up to WUXGA and 1080p60 with 24-bit color depth. The device features a maximum data rate of 5.95 Gb/s per lane, with two differential inputs and ten LVDS outputs. Power supply voltages include 3.3 V, 1.8 V, and 1.2 V, with maximum supply voltage at 3.6 V and minimum at 1.14 V. It is housed in a 64-pin WQFN package.

Feature Summary

• Supports dual-channel FPD-Link III input conversion to dual-pixel OpenLDI output for high-resolution video transmission.
• Integrates adaptive receive equalization with automatic temperature and cable aging compensation to maintain signal integrity over long cables.
• Provides full-duplex control capabilities via integrated I2C and SPI interfaces alongside audio data channels.

Applications

• Automotive central information displays
• Rear seat entertainment systems
• Digital instrument clusters

Procurement Notes

Verify the complete part number including suffixes such as TNKDTQ1 against official Texas Instruments documentation to ensure correct automotive qualification and packaging specifications. Confirm that the specific variant matches the required temperature grade and pinout configuration for the target application design.

Selection Notes

Select this component when interfacing FPD-Link III serializers with legacy LVDS displays requiring dual-pixel parallel output. Ensure the system design accommodates the 64-WQFN package dimensions and thermal requirements. Verify compatibility with upstream serializers like the DS90UB949-Q1 for proper link establishment and clock alignment.

Part Context

This device belongs to the DS90UB948-Q1 family of FPD-Link III deserializers designed for automotive vision applications. It serves as a bridge between serial camera links and parallel display interfaces, enabling simplified cabling and reduced EMI through differential signaling technologies inherent to the FPD-Link architecture.

Replacement Considerations

The DS90UH948-Q1 is a related model within the same product family offering similar deserialization functions. Verify pin-to-pin compatibility and register-level differences before substitution to ensure seamless integration into existing hardware designs without schematic modifications.
