XRT83L34IV

Overview

The XRT83L34IV is a four-channel T1/E1/J1 Line Interface Unit (LIU) manufactured by MaxLinear. It integrates short-haul and long-haul line interface capabilities within a single device, supporting both SH and LH modes for flexible deployment in telecommunications networks. The component operates with a supply voltage range of 3.0V to 5.5V and functions reliably across an industrial temperature range from -40°C to +85°C. It utilizes a 128-lead Thin Quad Flat Package (TQFP) for surface-mount installation. This integrated circuit provides essential signal conditioning and transmission functions required for digital carrier systems.

Feature Summary

• Integrates four independent T1/E1/J1 line interface channels into a single package
• Supports configurable short-haul and long-haul line interface operation modes
• Provides comprehensive signal processing for digital carrier transmission standards

Applications

• Telecommunications network infrastructure equipment
• Digital subscriber line access multiplexers (DSLAM)
• Carrier-grade transmission systems requiring T1/E1 connectivity

Procurement Notes

Verify the specific suffix IV against official MaxLinear documentation to confirm pinout and electrical specifications. Confirm current availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing board designs regarding the 128-lead TQFP footprint before procurement.

Selection Notes

Select this component when a design requires multiple T1/E1 interfaces with mixed distance requirements. The integration of both short-haul and long-haul capabilities reduces bill-of-materials complexity compared to using separate devices. Verify that the system power supply accommodates the specified voltage range and thermal management meets the industrial temperature requirements.

Part Context

This part belongs to the XRT83L34 series of telecom interface ICs. It serves as a core component for managing digital voice and data traffic over copper lines. The device replaces discrete solutions by consolidating line driver, receiver, and protection circuits into one integrated unit.

Replacement Considerations

Check for updated versions within the XRT83L34 family. Consult manufacturer notices for any product change notifications affecting pin compatibility or performance characteristics.
