DS90UR124QVS

Overview

The DS90UR124QVS is a DC-balanced 24-bit FPD-Link II deserializer manufactured by Texas Instruments, which acquired National Semiconductor. It operates with a pixel clock frequency range of 5 MHz to 43 MHz and supports data rates up to 1.03 Gbps. The device accepts one LVDS input and provides 24 LVCMOS outputs. It functions within a supply voltage range of 3 V to 3.6 V and is qualified to AEC-Q100 Grade 2 standards for automotive applications. The component is housed in a 64-pin TQFP package (10x10 mm) and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Supports displays with 18-bit color depth via 24:1 interface compression
• Enables AC-coupled data transmission using embedded clock with DC balancing
• Capable of driving up to 10 meters of shielded twisted-pair cable without a reference clock

Applications

• Automotive central information displays
• Automotive instrument cluster displays
• Automotive heads-up displays
• Remote camera-based driver assistance systems

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required packaging format, such as VS for tray or VSX for reel. Confirm that the AEC-Q100 Grade 2 qualification aligns with your specific automotive reliability requirements before finalizing procurement orders.

Selection Notes

Select this component when interfacing with FPD-Link II serializers like the DS90UR241. Ensure the display resolution and refresh rate fall within the 5 MHz to 43 MHz pixel clock limit. Verify that the system design accommodates the 64-pin TQFP footprint and that the 3.3V power supply tolerance meets the specified ±10% requirement for stable operation.

Part Context

This device belongs to the DS90URxxx-Q1 series, designed specifically for high-quality video transmission in automotive environments. It pairs with the DS90UR241 serializer to form a complete SerDes chipset. The Q1 designation indicates automotive-grade qualification, ensuring robustness against electromagnetic interference and harsh thermal conditions typical in vehicle interiors.

Replacement Considerations

The DS90UR124IVS/NOPB serves as a verified industrial-grade alternative within the same family. Both devices share identical pinouts and functional specifications but differ in qualification standards. Ensure the application does not strictly require automotive certification if considering non-Q1 variants.
