DS90C241IVS

Overview

The DS90C241IVS is a serializer from the DS90CR241 series manufactured by National Semiconductor. It converts 24-bit parallel RGB data into a high-speed serial LVDS stream for display interfaces. The device operates with a supply voltage range of 3 V to 3.6 V and supports pixel clock frequencies up to 85 MHz. It utilizes a 48-pin TQFP package suitable for surface-mount applications. The component functions within an industrial temperature range of -40°C to +85°C, providing reliable performance for automotive and industrial display systems requiring DC-balanced transmission.

Feature Summary

• Converts 24-bit parallel RGB video data into a serialized LVDS output stream
• Supports embedded clocking with DC balancing for AC-coupled transmission
• Includes built-in self-test (BIST) capabilities for link validation
• Features individual power-down controls for transmitter sections

Applications

• Automotive central information displays
• Instrument cluster displays
• Remote camera-based driver assistance systems

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor's logic and interface product lines. Confirm that the specific part number corresponds to the legacy National Semiconductor specification rather than the updated TI datasheet revision. Ensure the package marking and date code align with the original supplier documentation to avoid confusion with equivalent TI-branded components.

Selection Notes

Select this component when interfacing with FPD-Link II compatible deserializers such as the DS90UR241 or DS90UR241-Q1. Ensure the system design accommodates the 48-pin TQFP footprint and thermal requirements. Verify that the host processor can drive the required parallel input signals and that the cable length constraints fit within the specified reach for shielded twisted-pair applications.

Part Context

This serializer belongs to the DS90CRxxx family designed for long-reach display interfaces. It is often paired with the DS90CR242 deserializer to form a complete point-to-point link. The series supports backward compatibility with earlier LVCMOS-based display interfaces while offering improved noise immunity through differential signaling.

Replacement Considerations

• DS90UR241IVS/NOPB
• DS90UR241QVS/NOPB

FAQ

Does the DS90C241IVS require an external reference clock?

No, the serializer generates its own clock internally based on the input pixel clock; no external reference clock is required.

What is the maximum supported pixel clock frequency?

The device supports pixel clock frequencies up to 85 MHz.

Is the DS90C241IVS compatible with automotive environments?

Yes, it operates within the -40°C to +85°C temperature range and meets relevant automotive interface standards.
