DS90UR904QSQ/NOPB

Overview

The DS90UR904QSQ/NOPB is a serializer within the DS90UR903Q/DS90UR904Q family, designed for FPD-Link II applications. It serializes up to 18 bits of color data and one clock signal over a single differential pair. The device supports pixel clock frequencies from 10 MHz to 43 MHz. It operates with a 1.8 V supply voltage and meets AEC-Q100 Grade 1 qualification for automotive use. The component is housed in a 48-pin WQFN package with a 7x7 mm footprint, suitable for surface-mount installation across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Serializes high-speed video data and clock signals onto a single LVDS differential pair for long cable transmission.
• Supports flexible input configurations including RGB, YCbCr, and raw data formats via programmable registers.
• Integrates a bidirectional control channel allowing the deserializer to send configuration commands back to the serializer.

Applications

• Automotive rear-seat entertainment systems requiring high-quality video transmission.
• Vehicle navigation displays and instrument clusters.
• Industrial monitor interfaces needing reliable long-distance signaling.

Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component matches the required AEC-Q100 automotive grade certification for your target application environment. Cross-reference the manufacturing date code to avoid obsolete lots if long-term availability is critical for production planning.

Selection Notes

Select this component when using a compatible FPD-Link II deserializer, such as the DS90UR903Q or DS90UR908Q series. Confirm that the display interface timing requirements fall within the 10 MHz to 43 MHz operating range. Ensure the system design accommodates the 48-WQFN thermal pad requirements for adequate heat dissipation during continuous operation at maximum temperatures.

Part Context

This part belongs to the DS90UR90xQ family of serializers developed by Texas Instruments following its acquisition of National Semiconductor. These devices are engineered specifically for flat-panel display interfaces in automotive environments. They replace older parallel LVDS solutions by reducing pin count and cable complexity while maintaining signal integrity over longer distances.

Replacement Considerations

Direct functional equivalents include other members of the DS90UR903Q/DS90UR904Q family, such as the DS90UR903QSQ/NOPB. Verify pin compatibility and register settings before substituting with non-TI generic serializers, as protocol implementations may vary.
