XRT83VSH316IB-F

Overview

The XRT83VSH316IB-F is a telecommunications interface integrated circuit manufactured by MaxLinear. It functions as an eight-channel short-haul line interface unit (LIU) designed for T1/E1/J1 applications. The device integrates framer and LIU capabilities within a single package, supporting data rates of 1.544 Mbps and 2.048 Mbps. It utilizes R3 technology to ensure compliance with modern telecom standards. The component is housed in a BGA-225 surface-mount package, suitable for high-density board layouts. This specific model variant represents the short-haul configuration optimized for local loop or access network environments.

Feature Summary

• Integrates eight independent channel interfaces for simultaneous T1/E1/J1 signal processing
• Combines digital framing and line interface unit functions into a single silicon solution
• Supports short-haul transmission requirements with reduced power consumption profiles
• Utilizes advanced R3 technology for enhanced signal integrity and jitter performance

Applications

• Telecommunications access networks requiring multi-channel T1/E1 termination
• Short-haul digital subscriber line (DSL) amplifier systems
• Central office equipment for local loop expansion
• Network interface units in enterprise communication infrastructure

Procurement Notes

This component is officially designated as End-of-Life (EOL) by MaxLinear. Distribution availability is currently restricted, and standard procurement channels may not supply new units. Engineers should verify current stock status with authorized distributors and consider long-term supply agreements if immediate deployment is required. Replacement planning is strongly advised due to discontinuation status.

Selection Notes

Designers selecting this part must account for its EOL status and limited future availability. The XRT83VSH316IB-F is specifically configured for short-haul applications; alternative variants exist for long-haul scenarios but are electrically incompatible. Verification of the BGA-225 footprint compatibility and thermal management requirements is essential during the PCB layout phase. Cross-referencing with the official datasheet is mandatory to confirm pinout and electrical specifications before integration.

Part Context

The XRT83VSH316IB-F belongs to the XRT83 family of telecom interface ICs from MaxLinear. This series is widely recognized for integrating framer and LIU functions to reduce bill-of-materials complexity. The 'VSH' suffix typically denotes the short-haul variant within this product line, distinguishing it from long-haul counterparts. The family supports various packaging options, with the BGA format offering compact form factors for dense telecommunications hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements may require design modifications. Engineers should consult MaxLinear's official obsolescence notifications for recommended transition paths or updated product families that maintain functional equivalence.
