XRT75L04IVTR-F

Overview

The XRT75L04IVTR-F is a four-channel Line Interface Unit (LIU) manufactured by MaxLinear, designed for DS3, E3, and STS-1 telecommunications applications. It operates within a supply voltage range of 3.135 V to 3.465 V and draws a maximum supply current of 450 mA. The device supports data rates up to 51.84 Mb/s and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 176-LQFP surface-mount format with dimensions of 24x24 mm, this component integrates jitter attenuation capabilities suitable for high-speed digital signal processing in telecom infrastructure.

Feature Summary

• Integrates four independent channels for simultaneous DS3, E3, or STS-1 line interfacing
• Includes built-in jitter attenuation functionality to improve signal integrity
• Supports surface-mount installation via a compact 176-pin LQFP package

Applications

• Telecommunications network interface equipment
• Digital Signal Processing (DSP) systems requiring LIU integration
• High-speed serial data transmission infrastructure

Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm compliance details, as distributor listings may vary. Confirm that the 176-LQFP package matches your PCB footprint requirements. Check for End-of-Life status or discontinuation notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a four-channel solution for DS3/E3/STS-1 standards is required. Ensure the design accommodates the 3.135 V to 3.465 V power supply constraint. Verify that the 176-LQFP thermal and mechanical specifications align with the target enclosure and board layout constraints.

Part Context

This part belongs to the XRT75L04 series of Line Interface Units. It shares functional similarities with the XRT75L04IV-F tray version but utilizes tape-and-reel packaging. Other family members include variants with different channel counts or package types, such as the XRT75L03IV-F.

Replacement Considerations

The XRT75L04IV-F is a direct pin-compatible alternative differing primarily in packaging format. Verify if the tray packaging meets assembly requirements. No other cross-model substitutes are confirmed in the provided data.
