XRT75R12IB

Overview

The XRT75R12IB is a twelve-channel Line Interface Unit (LIU) manufactured by MaxLinear, designed for telecommunications applications. It supports E3, DS3, and STS-1 line interface standards with integrated SONET capabilities. The device operates within a voltage range of 3.3V to 5V and functions in temperatures from -45°C to 85°C. It is housed in a 420-ball TBGA package measuring 35x35 mm. This component serves as a critical interface unit for high-speed digital transmission systems.

Feature Summary

Integrates twelve independent channels for simultaneous signal processing
Supports multiple standard protocols including E3, DS3, and STS-1
Includes built-in SONET functionality for network synchronization
Operates across extended industrial temperature ranges

Applications

Telecommunications line interface units
SONET/SDH network equipment
Digital cross-connect systems
Multiplexer systems requiring E3/DS3 interfaces

Procurement Notes

Verify the specific suffix and revision level against official MaxLinear documentation before procurement. Confirm that the 420-ball TBGA package dimensions match the target PCB layout. Ensure compatibility with the required 3.3V to 5V power supply rails. Check for any lead-free or RoHS compliance requirements relevant to the manufacturing region.

Selection Notes

Select this component when a multi-channel LIU solution is required for E3, DS3, or STS-1 signals. Consider the 420-ball TBGA footprint during mechanical design. Evaluate thermal management needs for operation up to 85°C. Verify that the integrated SONET features meet the synchronization requirements of the target application.

Part Context

This part belongs to the XRT series of telecom interface ICs produced by MaxLinear, formerly Exar Corporation. The series includes various channel counts and protocol support options. The XRT75R12IB specifically addresses the need for dense, multi-channel line interfacing in carrier-grade networking hardware.

Replacement Considerations

Check for direct replacements within the XRT family, such as the XRT75R12DIB-F. Verify pinout compatibility and electrical specifications before substituting. Consult MaxLinear for current availability and recommended alternatives if the original part is discontinued.
