DS90CR483VJD

Overview

The DS90CR483VJD is an LVDS interface integrated circuit manufactured by Texas Instruments, formerly National Semiconductor. It functions as a 48-channel Link Serializer designed to convert parallel CMOS or TTL data into a serial LVDS stream. The device features eight drivers and forty-eight receivers, supporting data rates up to 672 Mb/s. It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. The component is housed in a TQFP-100 package suitable for surface mount applications. It supports input voltages between 800 mV and 2 V and has a maximum power dissipation of 2.3 W.

Feature Summary

• Converts parallel digital inputs into a serialized low-voltage differential signaling output stream
• Integrates multiple driver channels within a single compact surface-mount package
• Compatible with standard CMOS and TTL logic families for direct interfacing

Applications

• Video display interfaces requiring high-bandwidth parallel-to-serial conversion
• Industrial control systems utilizing LVDS communication links
• Electronic equipment needing reliable long-distance signal transmission

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the TQFP-100 package availability aligns with manufacturing requirements. Ensure compliance with RoHS directives if applicable to the specific revision. Check for humidity sensitivity classification to determine proper storage and handling protocols during assembly.

Selection Notes

Select this serializer when a design requires converting wide parallel buses into a serial LVDS format for transmission. Ensure the system operates within the specified 3.0 V to 3.6 V supply range. Verify that the target application supports the 672 Mb/s maximum data rate. Consider the thermal constraints associated with the 2.3 W power dissipation rating in the TQFP-100 enclosure.

Part Context

This component belongs to the DS90CR483 series of LVDS interface ICs. It serves as the transmitter counterpart to deserializers like the DS90CR484. The part was originally developed by National Semiconductor before its acquisition by Texas Instruments. It is part of the Channel Link family designed for high-speed data transport.

Replacement Considerations

The DS90CR483VJDX/NOPB offers identical electrical specifications but utilizes a tape-and-reel packaging format instead of trays. Designers should verify pin compatibility and mechanical outline dimensions when switching between these packaging variants.
