XRT75VL00IV

Overview

The XRT75VL00IV is a single-channel Line Interface Unit (LIU) manufactured by MaxLinear, designed for high-speed serial communication in telecom applications. It supports DS3, E3, and STS-1 standards with a data rate up to 51.84 Mbps. The device integrates jitter attenuation capabilities and operates on a 3.3V supply voltage. It is housed in a 52-pin TQFP package measuring 10x10 mm. This component serves as a critical interface for transmitting and receiving digital signals over telecommunications lines.

Feature Summary

• Integrates jitter attenuation functionality within the line interface unit
• Supports multiple high-speed serial communication standards including DS3, E3, and STS-1
• Designed for reliable signal transmission in telecommunications infrastructure

Applications

• Telecommunications network equipment requiring DS3/E3/STS-1 interfaces
• Digital subscriber line access multiplexers (DSLAMs)
• SONET/SDH terminal multiplexer systems

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm package integrity and pin alignment before integration into PCB designs. Check for recent product change notifications or lifecycle updates from MaxLinear to ensure long-term availability and support compatibility for production runs.

Selection Notes

Select this component when a single-channel LIU with integrated jitter attenuation is required for DS3, E3, or STS-1 applications. Ensure the design accommodates the 3.3V operating voltage and 52-pin TQFP footprint. Consider thermal management requirements associated with the TQFP package size during layout planning.

Part Context

The XRT75VL00IV belongs to the XRT75L series of telecom interface ICs from MaxLinear. It complements other multi-channel variants like the XRT75L03 and XRT75L04 by providing a specialized single-channel solution. This part fits within the broader portfolio of line interface units designed for standardizing digital signal transmission across various global telecommunications protocols.

Replacement Considerations

The XRT75VL00IV-F is a documented variant within the same family. Verify if the suffix indicates specific packaging or environmental compliance differences. No direct cross-manufacturer substitutes are publicly confirmed; evaluate functional equivalence carefully if considering alternative vendors.
