DS99R103TSQ

Overview

The DS99R103TSQ is a serializer manufactured by Texas Instruments, which acquired National Semiconductor. It converts 24-bit parallel LVCMOS data into a high-speed serial FPD-Link II or LVDS output stream. The device supports data rates up to 960Mbps and operates on a single 3V to 3.6V power supply. It is housed in a 48-WQFN (7x7) package with exposed pad for surface mount installation. The component is qualified to AEC-Q100 standards for automotive applications and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Converts 24-bit parallel digital video data into a single differential serial link
• Supports FPD-Link II and standard LVDS signaling protocols
• Integrated clock recovery circuitry for synchronous data transmission
• Automotive-grade qualification ensuring reliability in harsh environments

Applications

• Automotive rear-view camera systems
• In-vehicle infotainment display interfaces
• Digital dashboard and instrument cluster connections
• Side-view mirror camera links

Procurement Notes

Verify the current status of this part number as it may be obsolete or superseded by newer revisions. Confirm that the supplier provides valid traceability documentation for automotive components. Check for RoHS compliance status and ensure the package matches the required footprint. Validate that the specific suffix aligns with the intended thermal and electrical requirements for the target application.

Selection Notes

Select this component when a serializer is required to bridge parallel logic to a long-distance serial link. Ensure the system design accommodates the 48-pin WQFN thermal dissipation needs. Verify that the downstream deserializer matches the FPD-Link II protocol. Consider the voltage levels of the source interface to confirm compatibility with the LVCMOS inputs.

Part Context

This component belongs to the DS99R10x family of serializers designed for short-to-medium distance digital video transmission. These devices are commonly paired with deserializers like the DS99R104 to form complete video links. The transition from National Semiconductor to Texas Instruments means datasheets and support resources are now managed under the TI brand.

Replacement Considerations

Check for direct replacements such as the DS99R103TSQX/NOPB if the original is discontinued. Verify pinout compatibility before substituting with other serializers in the DS90C series. Ensure any alternative maintains the same 24-bit width and LVDS output characteristics.
