PEF 22624 E V2.2-G

Telecom Overview

The Infineon PEF 22624 E V2.2-G is a two-channel Symmetric DSL Front End (SDFE-2) belonging to the second-generation SOCRATES family of SHDSL transceivers. Designed for pure TDM applications, it integrates a DSP, microcontroller, analog front end, line driver, and memory into a single chip. The device complies with ETSI TS 101524 and ITU G.991.2 standards, supporting payload data rates from 144 kbit/s up to 6.392 kbit/s with 8 kbit/s granularity. It operates on 3.3 V and 1.8 V power supplies with approximately 500 mW power consumption per channel within a -40°C to +85°C temperature range, housed in a P-LBGA-324 package.

Telecom Feature Summary

• Fully integrated solution combining DSP, microcontroller, analog front end, line driver, and memory
• Supports payload data rates from 144 kbit/s up to 6.392 kbit/s with 8 kbit/s granularity
• Includes tunable hybrid for optimal loop adaptation and M-pair functionality
• Features programmable framer with support for multiple TDM clocks

Telecom Applications

• ISDN primary rate access replacement
• SHDSL repeater/regenerator
• Digital Loop Carrier (DLC) Systems
• Extended range full and fractional E1/T1
• Wireless infrastructure

Telecom Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches project requirements. Check current availability status as lifecycle stages may affect supply continuity. Ensure compliance with RoHS directives and relevant environmental regulations before integration.

Telecom Selection Notes

Select this component for designs requiring compliant SHDSL transceiver functionality with low BOM count. Consider its pin and software compatibility with other SDFE-4/2/1 variants if channel scalability is needed. Evaluate the 500 mW per channel power consumption against thermal constraints in remote powered repeater designs.

Telecom Part Context

This part belongs to the SOCRATES family of symmetric DSL front ends. It shares physical characteristics and interface protocols with the four-channel PEF 24624 E and one-channel PEF 21624 E models. All variants utilize the same P-LBGA-324 package and offer pin and software compatibility for streamlined design transitions.

Telecom Replacement Considerations

Direct replacements include the PEF 24624 E for quad-channel needs or the PEF 21624 E for single-channel applications due to shared architecture. Verify that any substitute maintains the required ITU G.991.2 compliance and TDM clock support.
