DS90CR482VS

Overview

The DS90CR482VS is a 48-bit LVDS Channel Link Serializer/Deserializer (SER/DES) designed for high-speed data transmission. It supports input clock frequencies ranging from 65 MHz to 112 MHz, enabling data rates up to 672 Mbps. The device converts 48 bits of CMOS/TTL data into eight LVDS data channels and one LVDS clock channel for transmission. On the receiving end, it deserializes the LVDS signals back into 48-bit LVCMOS/TTL data. Operating on a single +3.3V supply, it features a TQFP-100 package with an operating temperature range of -10°C to +70°C.

Feature Summary

• Reduces cable and connector size by multiplexing 48-bit data onto eight LVDS lines and one clock line, significantly lowering system cost and physical footprint.
• Incorporates pre-emphasis technology to mitigate cable load effects and optional DC-balanced encoding to reduce inter-symbol interference.
• Provides cable skew correction capabilities to compensate for timing mismatches across LVDS data bits, ensuring signal integrity over varying cable lengths.

Applications

• High-resolution flat panel display interfaces requiring reduced cabling complexity.
• Medical imaging systems such as X-ray detectors and ultrasound scanners.
• Industrial automation equipment utilizing high-speed sensor data acquisition.

Procurement Notes

Verify the manufacturer origin carefully, as the component was originally developed by National Semiconductor and is now supported by Texas Instruments following their acquisition. Confirm that the specific suffix indicates the commercial temperature grade and packaging variant. Ensure RoHS compliance documentation aligns with current regulatory requirements for your region before finalizing procurement orders.

Selection Notes

Select this component when reducing the pin count and cable width for 48-bit parallel data buses is critical. It is suitable for applications requiring data rates between 65 MHz and 112 MHz. Consider the DS90CR481 if only serializer functionality is needed, or the DS90CR483 if extended temperature ranges are required beyond the commercial limits of the VS package.

Part Context

This part belongs to the DS90CR48x series of LVDS interface ICs, which were widely adopted for FPD-Link applications. Originally manufactured by National Semiconductor, these devices established a standard for reducing complex parallel connections in display and imaging systems. The series remains relevant for legacy designs and upgrades where LVDS reliability and bandwidth efficiency are prioritized.

Replacement Considerations

The DS90CR482VS may be replaced by the DS90CR482VM or other variants within the same family depending on package or temperature requirements. Verify pin compatibility and electrical specifications against the specific datasheet revision, as Texas Instruments continues to support this product line after acquiring National Semiconductor's portfolio.
