DS99R103TVS/NOPB

Overview

The DS99R103TVS/NOPB is a DC-balanced serializer manufactured by Texas Instruments, designed for high-speed parallel-to-serial data conversion. It accepts up to 24-bit parallel inputs and converts them into a single differential LVDS serial output stream. The device operates within a frequency range of 3 MHz to 40 MHz and supports a supply voltage between 3.0 V and 3.6 V. It is housed in a 48-pin Thin Quad Flatpack (TQFP) package with dimensions of 7x7 mm. The component functions as part of the FPD-Link II interface ecosystem, enabling reliable transmission over long cables.

Feature Summary

• Converts 24-bit parallel data into a single LVDS serial channel
• Supports DC-balanced encoding for reliable clock recovery
• Compatible with FPD-Link II standard specifications

Applications

• Automotive display systems requiring long cable runs
• In-vehicle infotainment video transmission
• Digital cockpit display interfaces

Procurement Notes

Verify current availability status as discontinuation notices may apply. Confirm package integrity and moisture sensitivity level handling procedures upon receipt. Cross-reference manufacturer lot codes against official product change notifications to ensure compliance with updated material specifications before integration into production designs.

Selection Notes

Select this serializer when interfacing with compatible deserializers such as the DS90UR103/104 series. Ensure the system design accommodates the required 3.3 V power supply and thermal dissipation characteristics of the TQFP-48 package. Validate that the target application frequency falls within the specified 3 MHz to 40 MHz operational range for optimal signal integrity.

Part Context

This component belongs to the DS99R10x family of serializers from Texas Instruments, originally developed under National Semiconductor. It serves as the transmitting counterpart to specific deserializers in the FPD-Link architecture. The device is engineered to replace legacy parallel display interfaces, reducing pin count and cable complexity in automotive and industrial applications.

Replacement Considerations

Direct functional equivalents include the DS99R101TVS/NOPB and DS99R105TVS/NOPB. Verify pin compatibility and electrical parameters before substitution. Consult official datasheets for any differences in operating temperature ranges or packaging variations.
