PEB4166TV1.1

Telecom Overview

The PEB4166TV1.1 is a Subscriber Line Interface Circuit (SLIC) manufactured by Infineon Technologies, designed for analog telephony applications. It integrates BICMOS technology within a plastic PDSO20 surface-mount package to facilitate compact circuit board layouts. The device functions as a two-wire to four-wire converter, enabling the connection of analog subscriber lines to digital signal processing systems. Key electrical characteristics include an operating supply voltage range typically centered around 48V DC, consistent with standard telephone line powering requirements. The component supports essential interface functions such as ring generation, battery feed, and hybrid balancing for voice transmission.

Telecom Feature Summary

• Integrates two-wire to four-wire conversion capabilities for efficient signal routing between analog lines and digital processors.
• Utilizes BICMOS semiconductor technology to combine high-voltage handling with low-power digital logic in a single chip.
• Provides integrated ring generation and battery feed circuits to power remote subscriber handsets directly from the central office.

Telecom Applications

• Analog telephone exchange systems
• Voice over IP (VoIP) gateway interfaces
• Central office subscriber line cards

Telecom Procurement Notes

Verify the specific suffix TV1.1 against official Infineon documentation to confirm pinout compatibility and revision level. Ensure the source provides a valid datasheet or product specification sheet that explicitly lists this part number. Cross-reference the manufacturer designation, as historical lineage may involve Intel or Lantiq branding before Infineon's acquisition of those divisions.

Telecom Selection Notes

Select this component when designing legacy analog telephony interfaces requiring integrated hybrid balancing and line powering. Confirm that the system architecture supports the required BICMOS voltage levels and that the SO-20 package footprint matches the PCB design constraints. Evaluate thermal dissipation requirements based on the expected current load during ring generation and battery feed operations.

Telecom Part Context

This component belongs to the family of SLICs originally developed under Intel and later Lantiq brands before being absorbed into Infineon Technologies' portfolio. These devices are critical for bridging traditional Public Switched Telephone Network (PSTN) infrastructure with modern digital switching equipment. The PEB series represents a mature technology block used extensively in telecommunications hardware deployed over previous decades.

Telecom Replacement Considerations

Publicly confirmed direct substitute part numbers for the PEB4166TV1.1 are not available in the provided reference data. Designers should consult official Infineon replacement guides or contact technical support for qualified alternatives, as generic equivalents may lack specific electrical matching for hybrid balance and protection features.
