PEF49000ELV1.1

Telecom Overview

The PEF49000ELV1.1 is a high-performance, single-chip Ethernet line interface unit (LIU) designed for SONET/SDH applications. It integrates four independent serial-to-parallel interfaces compliant with ITU-T G.823 and G.825 standards. The device supports data rates up to 622.08 Mbps and includes integrated clock recovery circuits. Key electrical parameters include a supply voltage range of 3.0 V to 3.6 V and an operating temperature range from -40°C to +85°C. It utilizes a 144-pin TQFP package.

Telecom Feature Summary

• Integrates four fully functional SONET/SDH line interface units on a single die
• Provides robust clock and data recovery (CDR) circuitry for each channel
• Supports standard STM-1/OC-3c signal formats with low jitter performance
• Includes comprehensive diagnostic capabilities for fault detection and monitoring

Telecom Applications

• SONET/SDH multiplexers and add-drop multiplexers (ADM)
• Optical network terminals (ONT) and units (ONU)
• Carrier-grade Ethernet over SONET/SDH equipment
• Telecommunications infrastructure requiring high-density LIU integration

Telecom Procurement Notes

Verify the specific suffix 'LV1.1' against the manufacturer's current datasheet to confirm pinout compatibility and revision differences. Ensure that the source documentation explicitly lists this part number as an active or supported component for your design lifecycle. Cross-reference the package type and thermal specifications with your board layout requirements before finalizing procurement.

Telecom Selection Notes

Select this component when designing systems requiring multiple SONET/SDH ports within a compact footprint. It is suitable for applications needing precise timing alignment and low bit error rates. Consider the power consumption and thermal dissipation characteristics of the 144-pin TQFP package during the initial hardware architecture phase to ensure adequate cooling solutions are implemented.

Telecom Part Context

This component belongs to the PEF49000 family of Ethernet Line Interface Units developed by Lantiq (formerly Infineon Technologies). The family is engineered to simplify the design of high-speed optical communication networks by consolidating multiple physical layer functions into a single integrated circuit, reducing bill of materials and board space.

Telecom Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided reference material. Verify compatibility with newer revisions of the PEF49000 series or alternative LIU chips only through official manufacturer cross-reference guides.
