DS99R105SQX/NOPB

Overview

The DS99R105SQX/NOPB is a serializer manufactured by Texas Instruments, designed for display interface applications. It operates within a frequency range of 3 MHz to 40 MHz and supports 24-bit color depth. The device converts parallel LVCMOS inputs into a single FPD-Link or LVDS output stream with a data rate of 960 Mbps. It is housed in a 48-WQFN package (7x7 mm) and is qualified under AEC-Q100 standards for automotive use. The component functions within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Supports high-speed serial transmission for multi-channel display interfaces
• Automotive-grade qualification ensuring reliability in vehicle environments
• Integrates DC-balanced encoding for signal integrity maintenance

Applications

• Automotive infotainment systems requiring high-bandwidth video transmission
• Digital cockpit displays connecting processing units to screen panels
• ADAS camera-to-display signal routing architectures

Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the design accounts for the AEC-Q100 grade requirements if deployed in automotive contexts. Cross-reference the 48-WQFN thermal pad layout guidelines during PCB design to maintain optimal heat dissipation within the specified operating temperature limits.

Selection Notes

Select this component when a 24-bit serializer is required for FPD-Link II or LVDS interfaces in automotive environments. It serves as the serializing counterpart to deserializers like the DS99R106. Consider the 48-pin WQFN footprint constraints and the need for a 3V to 3.6V power supply rail compatible with the system's logic levels.

Part Context

This part belongs to the DS99R1xx series of serializers from Texas Instruments, specifically engineered for FPD-Link applications. It pairs with corresponding deserializers to extend cable lengths between source devices and displays. The SQ suffix indicates automotive qualification, while the X suffix typically denotes reel packaging, distinguishing it from cut-tape or tube variants.

Replacement Considerations

The DS99R105SQ/NOPB is a direct pin-compatible alternative without the reel-specific suffix. Designers should verify that the packaging difference does not impact automated assembly processes. No functional electrical replacements are documented in the provided sources.
