• Supports DS3/E3 and E3/T3 digital transmission standards
• Provides analog loss of signal detection mechanisms
• Includes hardware-based clock generation and flag processing

Telecom Applications

• Digital multiplexer systems
• Telecommunications network infrastructure
• Base station connectivity modules

Telecom Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific revision suffix matches project requirements. Request official datasheets and compliance certificates prior to integration. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package damage during assembly processes.

Telecom Selection Notes

Select this component when designing systems requiring dedicated DS3/E3 or E3/T3 framing without external microcontroller dependency. Evaluate thermal performance due to power dissipation characteristics in dense PCB layouts. Compare pin compatibility with existing designs if upgrading from previous generations. Consider the 272-BGA footprint constraints for routing density and manufacturing capabilities.

Telecom Part Context

This IC belongs to the PEF series of telecommunications interface chips developed by Infineon Technologies. It complements other products like the PEF 22628 by focusing on higher-rate TDM interfaces rather than DSL symmetric transceivers. The series targets carrier-grade equipment manufacturers needing reliable physical layer framing solutions.

Telecom Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference options directly with Infineon technical support or authorized channel partners for legacy replacement strategies.
