PSB 21393 H V1.3

Telecom Overview

The PSB 21393 HV1.3 is a SCOUT-PX integrated circuit designed for digital voice terminals, combining the functions of an ARCOFI-SP audio codec and a SmartLink-P subscriber access controller on a single CMOS chip. It supports IOM-2 modular interfaces and UPN transceiver connectivity. The device operates with a 3.3V or 5V supply voltage and is housed in a P-MQFP-44 package. Key capabilities include speakerphone performance, acoustic echo cancellation support, tone generation, and comprehensive Layer-1 and basic Layer-2 protocol handling for digital terminal connections.

Telecom Feature Summary

• Integrates ARCOFI-SP audio codec functionality with SmartLink-P subscriber access controller
• Supports modular expansion via IOM-2 interface for features like acoustic echo cancellation
• Provides complete Layer-1 and basic Layer-2 functions for UPN digital terminal connections
• Includes analog front end with programmable amplifiers and multiple analog inputs/outputs

Telecom Applications

• Basic PBX voice terminals
• High-end featurephones requiring acoustic echo cancellation
• Digital voice terminal solutions utilizing IOM-2 modular extensions

Telecom Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific version suffix matches project requirements. Review the datasheet for absolute maximum ratings and operating conditions to ensure compatibility with system power supplies and environmental constraints before integration.

Telecom Selection Notes

Select this model when speakerphone functionality and acoustic echo cancellation are required within a single-chip solution. Compare against the PSB 21391 if speakerphone features are unnecessary. Ensure the design accommodates the P-MQFP-44 package dimensions and utilizes the appropriate 3.3V or 5V supply voltage configuration as specified in the electrical characteristics.

Telecom Part Context

This component belongs to the SCOUT family of wired communications ICs from Infineon Technologies. It serves as an evolution of earlier discrete solutions by integrating separate codec and transceiver chips into one unit. The PSB 21393 specifically extends the base PSB 21391 by adding advanced speakerphone processing capabilities, targeting more complex terminal designs.

Telecom Replacement Considerations

The PSB 21391 is the non-speakerphone variant within the same family. Verify functional requirements before substitution. No other direct public substitutes are documented.
