Overview
The DS90CR483VJDX/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a 48-bit channel link serializer, converting parallel CMOS or TTL inputs into serial LVDS outputs. The device features eight drivers and supports data rates up to 672 Mb/s. It operates within a supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V. The component is housed in a 100-pin TQFP package and is designed for surface-mount installation. It maintains an operating temperature range from -10°C to +70°C and has a maximum power dissipation of 2.3 W.
Feature Summary
- Serializes 48-bit parallel data streams into high-speed LVDS signals for long-distance transmission.
- Accepts standard CMOS or TTL logic levels at the input stage without requiring external level shifting.
- Integrates eight independent LVDS drivers to manage the serialized output channels efficiently.
Applications
- Flat panel display interfaces requiring high-bandwidth video signal transmission.
- Industrial control systems utilizing LVDS communication protocols.
- Medical imaging equipment needing reliable digital signal serialization.
Procurement Notes
Verify the obsolete status indicated by the NRND designation before procurement planning. Confirm that the non-lead-free version meets environmental compliance requirements for the target market. Ensure the 100-TQFP footprint matches the PCB layout constraints. Validate that the -10°C to +70°C commercial temperature range satisfies the operational environment specifications.
Selection Notes
Select this component when a 48-bit serializer is required for LVDS applications. Compare against the DS90CR285 if fewer channels are sufficient. Consider the DS90CR483VJDX/NOPB only if the specific 100-TQFP package and commercial temperature range align with the design needs. Evaluate the direct replacement availability due to the end-of-life status of the lead-based variant.
Part Context
This part belongs to the DS90CR483 series of LVDS interface ICs. It serves as the successor to the discontinued DS90CR483VJDX, offering RoHS-compliant manufacturing while maintaining identical electrical characteristics. The series is designed for high-speed data transmission in display and industrial environments.
Replacement Considerations
The DS90CR483VJDX is the direct predecessor and pin-compatible substitute. Verify that the lead-free composition of the NOPB suffix does not impact thermal management requirements compared to the older version.
FAQ
Is the DS90CR483VJDX/NOPB RoHS compliant?
Yes, the /NOPB suffix indicates that the component is RoHS compliant and lead-free.
What is the maximum data rate supported by this serializer?
The device supports a maximum data rate of 672 Mb/s.
Does this component require external termination resistors?
LVDS interfaces typically require external termination resistors across the differential pairs to match the line impedance, though internal biasing may be present.
