DS99R101VSX/NOPB

Serializers, Deserializers Overview

The DS99R101VSX/NOPB is a DC-balanced serializer manufactured by Texas Instruments, originally developed under the National Semiconductor brand. It converts 24 parallel LVCMOS inputs into a single differential LVDS output stream. The device supports data rates up to 960 Mb/s, corresponding to pixel clock frequencies between 3 MHz and 40 MHz. It operates on a single 3.3 V power supply with a valid range of 3.0 V to 3.6 V. The component is housed in a 48-pin TQFP package and is rated for commercial operating temperatures from 0°C to +70°C.

Serializers, Deserializers Feature Summary

• Converts 24-bit parallel digital video signals into a high-speed serial LVDS format
• Maintains signal integrity through DC-balanced encoding schemes
• Integrates internal voltage reference and termination resistors

Serializers, Deserializers Applications

• Flat panel display interfaces using FPD-Link technology
• Digital video transmission systems requiring low pin-count connections
• Industrial imaging equipment with parallel-to-serial conversion needs

Serializers, Deserializers Procurement Notes

This specific part number indicates an obsolete status within the manufacturer's portfolio. Verification of current availability requires checking authorized distributors for remaining stock or evaluating end-of-life notifications. Designers should confirm that the legacy component meets long-term supply requirements before finalizing procurement plans.

Serializers, Deserializers Selection Notes

Select this component when a 24-bit parallel input must be serialized for transmission over a single LVDS pair. Ensure the system design accommodates the 3.3 V logic levels and the specific thermal constraints of the TQFP-48 package. Verify that the target application frequency falls within the 3 MHz to 40 MHz operational window defined by the datasheet.

Serializers, Deserializers Part Context

The DS99R101 belongs to the DS99R10x family of serializers designed for flat panel displays. This series enables the connection of display drivers to source drivers via a standardized serial interface. The 'VSX' suffix denotes the specific tape-and-reel packaging variant of the VS series, distinguishing it from tray-packaged equivalents.

Serializers, Deserializers Replacement Considerations

Direct replacements include the DS99R101VS/NOPB and DS99R101VS. These variants share identical electrical characteristics and pinouts but differ in shipping packaging. Alternative families such as the DS90C124 offer similar functionality with potentially different qualification standards.
