DS90CR483AVJDX/NOPB

Overview

The DS90CR483AVJDX/NOPB is an LVDS interface integrated circuit functioning as a 48-bit channel link serializer. It converts parallel CMOS or TTL inputs into a serial LVDS output stream, supporting data rates from 33 MHz to 112 MHz per channel with a maximum aggregate throughput of 5.38 Gbps. The device operates on a single 3V to 3.6V power supply and features eight drivers for the serialized output. Designed for surface-mount applications, it is housed in a 100-pin TQFP package (14x14 mm) suitable for automated assembly. The component supports an operating temperature range of -10°C to +70°C.

Feature Summary

• Serializes 48 parallel digital input channels into a high-speed differential LVDS output stream
• Accepts standard CMOS or TTL logic levels at the input interface
• Integrates eight independent LVDS drivers for robust signal transmission

Applications

• Flat panel display systems requiring high-bandwidth video data transfer
• Industrial control networks utilizing LVDS interconnect standards
• Medical imaging equipment needing reliable parallel-to-serial conversion

Procurement Notes

Verify the specific suffix 'A' against official Texas Instruments documentation, as standard listings often reference the DS90CR483VJDX/NOPB variant. Confirm RoHS compliance status directly with the manufacturer, as some sources indicate non-compliance for similar legacy parts. Ensure the 100-TQFP footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a system requires converting a wide 48-bit parallel bus into a compact serial LVDS link. It is appropriate for designs needing to reduce trace count between boards while maintaining high data integrity over moderate distances. Verify that the host processor can handle the required 33-112 MHz clock speeds for the serialization process.

Part Context

This part belongs to the DS90CR483 series of LVDS serializers manufactured by Texas Instruments. It serves as a bridge between parallel digital interfaces and serial LVDS transmission lines. The device is commonly used in display driver architectures where space efficiency and signal quality are critical requirements for modern electronic systems.

Replacement Considerations

The DS90CR483VJDX/NOPB is listed as a direct replacement for the discontinued DS90CR483VJDX. Verify if the 'A' suffix denotes a specific revision or grade change compared to the standard VJDX/NOPB version.
