XRT75R03DIV-F

Overview

The XRT75R03DIV-F is a telecommunications interface integrated circuit manufactured by MaxLinear, classified as a Line Interface Unit (LIU). It supports three channels for DS3, E3, and STS-1 line standards. The device operates on a single power supply voltage ranging from 3.3 V to 5 V. It is designed for surface-mount installation in a PBGA-217 package. The component functions within a minimum operating temperature of -40°C and a maximum operating temperature of +85°C.

Feature Summary

Provides three independent channels for DS3, E3, and STS-1 line interface unit applications
Supports flexible power supply operation between 3.3 V and 5 V levels
Integrated into a compact PBGA-217 surface-mount package

Applications

DS3/E3/STS-1 Line Interface Units
Telecommunications Interface ICs
Clock Synthesizers / Jitter Cleaners

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution availability is currently restricted or unavailable through major distributors such as Mouser. Verification of current stock status and valid replacement sources is required before procurement planning.

Selection Notes

Engineers should verify compatibility with existing 3.3 V to 5 V power rails and ensure the PBGA-217 footprint matches the design. Due to the discontinued status, alternative sourcing strategies or redesign efforts may be necessary to maintain long-term supply chain stability.

Part Context

The XRT75R03DIV-F belongs to the XRT75R series of telecom interface ICs. This family includes variants like the XRT75R06DIB-F and XRT75R03DES, which share similar LIU functionalities but differ in channel counts and specific package configurations. The series targets high-density telecommunications equipment requiring robust line interface capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the End-of-Life status, direct pin-to-pin replacements are not explicitly listed. Designers must consult official obsolescence notices for potential recommended alternatives.
