PEF 24624 E V2.1-G

Telecom Overview

The Infineon PEF 24624 E V2.1-G is a four-channel Symmetric DSL Front End (SDFE-4) belonging to the SOCRATES-16Bis family of SHDSL transceivers. Designed for high-density DSLAM and DLC applications, it integrates a DSP, microcontroller, AFE, line driver, and memory within a single chip. The device supports symmetric DSL protocols up to 6 Mbit/s, including G.SHDSL.bis, Packet TC, and M-pair mode. It operates with 3.3 V and 1.8 V power supplies and achieves a power consumption of 550 mW per channel at full speed. The component utilizes a P-LBGA-324 package.

Telecom Feature Summary

• Fully integrated four-channel SHDSL transceiver combining DSP, microcontroller, AFE, line driver, and memory
• Supports advanced SHDSL protocols up to 6 Mbit/s, including Packet TC and M-pair mode
• Features tunable hybrid for optimal loop adaptation and reach
• Requires only external passive components and dual voltage power supplies

Telecom Applications

• High-density DSLAM systems
• Digital Loop Carrier (DLC) equipment
• Multi-service Access Point (MSAP)
• Central Office line cards
• Ethernet First Mile (EFM) Equipment

Telecom Procurement Notes

Verify the specific revision suffix against official Infineon documentation to ensure compatibility with required firmware or hardware configurations. Confirm that the P-LBGA-324 package dimensions align with the target PCB layout. Check current product status as older generation telecom ICs may have limited availability or end-of-life implications.

Telecom Selection Notes

Select this component when designing high-density linecards requiring low power consumption per channel. Ensure the system architecture accommodates the SDC-16i controller alongside multiple SDFE-4 units. Verify support for required backplane interfaces such as UTOPIA, POS PHY, or MII in the companion controller.

Telecom Part Context

This part serves as the front-end transceiver unit within the five-member SOCRATES-16Bis chipset. It pairs with the SDC-16i (PEF 24625 E) controller to form a complete 16-channel solution. The design emphasizes cost savings through reduced BOM by eliminating the need for external RAM or controllers for channel bundling.

Telecom Replacement Considerations

Direct replacements are not explicitly listed in public datasheets. Consider other members of the SOCRATES family or newer generations from Infineon after verifying interface compatibility and pinout alignment.
