DS90CR481VJD/NOPB

Overview

The DS90CR481VJD/NOPB is a CMOS serializer designed for high-speed data transmission within the LVDS Channel Link family. It converts 48-bit parallel CMOS or TTL data into eight serial LVDS data streams and one clock signal, supporting input clock frequencies from 65 MHz to 112 MHz. The device operates on a single 3.3 V power supply with 5 V-tolerant inputs. Key technical specifications include a maximum data rate of 672 Mb/s per channel, an operating temperature range of -10°C to +70°C, and a TQFP-100 package. Power dissipation is rated at 2.3 W.

Feature Summary

• Reduces cable and connector size by multiplexing 48 bits into eight LVDS channels
• Includes pre-emphasis circuitry to compensate for cable load effects
• Features skew correction to align data bits relative to the clock signal

Applications

• High-resolution flat panel display interfaces
• Medical imaging equipment requiring high bandwidth
• Industrial automation control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be designated as Not Recommended for New Designs (NRND). Ensure storage conditions account for moisture sensitivity levels prior to soldering.

Selection Notes

Select this component when a 48-bit parallel-to-serial conversion is required for LVDS transmission. Verify that the system environment stays within the specified commercial temperature limits. Ensure the receiving end utilizes a compatible deserializer, such as the DS90CR482, to complete the link architecture.

Part Context

This device belongs to the National Semiconductor DS90CR48x series of LVDS interface integrated circuits. It functions as the transmitter counterpart in a serialized link pair, working alongside the DS90CR482 deserializer. The series is engineered to minimize electromagnetic interference while maximizing data throughput over long cables.

Replacement Considerations

The DS90CR481VJD is the direct predecessor without the NOPB suffix. Check datasheets for pin compatibility and electrical parameter differences before substituting.
