XRT75L00IVTR-F

Overview

The XRT75L00IVTR-F is a telecom interface integrated circuit manufactured by MaxLinear, Inc. It functions as a clock synthesizer and jitter cleaner designed for Line Interface Units (LIU) applications. The device supports E3, DS3, and STS-1 signal standards with four independent channels. It operates on a single 3.3V power supply and is housed in a 52-LQFP surface-mount package. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates clock synthesis and jitter attenuation capabilities within a single chip
• Supports multiple high-speed digital telecommunication standards including E3, DS3, and STS-1
• Provides four independent channel configurations for parallel signal processing

Applications

• Telecommunications line interface units requiring precise clock recovery
• Digital subscriber line systems utilizing DS3 or E3 protocols
• SONET/SDH network equipment implementing STS-1 interfaces

Procurement Notes

This component is currently listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock new units. Verify production status and lead times carefully before design-in. Sourcing should focus on authorized channels to ensure authenticity given the discontinued status.

Selection Notes

Select this part when designing systems requiring synchronized clock generation for four-channel telecom interfaces. It is suitable for applications needing jitter cleaning at 3.3V logic levels. Ensure the PCB layout accommodates the 52-LQFP footprint and thermal requirements for the specified industrial temperature range.

Part Context

The XRT75L00 series belongs to MaxLinear's portfolio of telecom interface solutions. This specific model focuses on clock management for LIU architectures. It complements other devices like the XRT75L04 series which handle physical layer interfacing without integrated clock synthesis.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative sourcing requires verification of functional compatibility with existing system designs.
