PEB 4264 T V1.2

Telecom Overview

The PEB 4264 T V1.2 is a Dual Channel Subscriber Line Interface Circuit (DuSLIC) from Infineon's VINETIC family, designed for analog termination in access networks and customer premises equipment. It integrates two complete subscriber line interfaces within a single package, supporting both analog signaling and digital control functions. The device operates with a standard supply voltage and provides necessary biasing and protection for telephone lines. It features integrated hybrid circuits, echo cancellation, and ringing detection capabilities essential for traditional telephony applications.

Telecom Feature Summary

• Integrates dual subscriber line interface channels for compact system design
• Supports full analog signaling including dial pulse and DTMF generation
• Includes integrated hybrid circuits and echo cancellation functionality
• Provides comprehensive line protection against overvoltage and surge events

Telecom Applications

• Analog telephone adapters and gateways
• Central office switching systems
• PBX and VoIP gateway hardware
• Customer premises telecommunications equipment

Telecom Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt as the unit utilizes a PDSO-20 housing. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference ordering information with official Infineon documentation to confirm revision compatibility before integration into production designs.

Telecom Selection Notes

Select this component when designing systems requiring dual-channel analog termination within a constrained footprint. Evaluate thermal performance requirements based on the specific operating environment and power dissipation characteristics. Consider the integration of external components for ringing detection and battery feed optimization. Assess compatibility with existing digital control interfaces used in the target application architecture.

Telecom Part Context

This component belongs to the VINETIC family of codec and SLIC chipsets, which are optimized for access network applications. The DuSLIC architecture combines two independent subscriber line interfaces to reduce board space and component count compared to single-channel solutions. It represents a specialized solution for telecom infrastructure rather than general-purpose interface chips.
