DS90CR482VSX/NOPB

Overview

The DS90CR482VSX/NOPB is a CMOS TTL to LVDS deserializer manufactured by Texas Instruments. It converts 48-bit parallel data into eight serial LVDS data streams and one clock stream for transmission. The device supports input clock frequencies from 65 MHz to 112 MHz, achieving data rates up to 672 Mbps. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The component is housed in a 100-pin Thin Quad Flatpack (TQFP) package and functions within an operating temperature range of -10°C to +70°C.

Feature Summary

• Reduces cable and connector size by multiplexing 48 bits into eight LVDS channels
• Includes pre-emphasis circuitry to mitigate cable loading effects
• Features DC balance encoding to minimize inter-symbol interference
• Provides cable skew correction capabilities

Applications

• High-speed backplane interconnects
• Flat panel display link systems
• Industrial equipment communication links

Procurement Notes

Verify the specific suffix 'VSX' against the official datasheet to confirm the tape-and-reel packaging variant and commercial temperature grade. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design. Cross-reference the manufacturer's latest documentation to validate RoHS compliance status and any recent lifecycle changes.

Selection Notes

Select this component when a high-density deserialization solution is required for 48-bit data paths. It serves as the receiver counterpart to serializers like the DS90CR481. Consider the TQFP-100 package constraints and the 3.3V logic level compatibility. Verify that the system environment remains within the specified -10°C to +70°C operational range for reliable performance.

Part Context

This device belongs to the DS90CR48x series of LVDS interface integrated circuits designed for high-speed data transmission. It complements the DS90CR481 serializer to form a complete channel link pair. The series addresses EMI reduction and physical interconnection limitations in digital video and industrial applications.

Replacement Considerations

The DS90CR484 is a documented compatible alternative within the same product family. Verify pin-to-pin compatibility and functional equivalence before substitution.
