PEB 4264-2 T V1.2

Telecom Overview

The PEB 4264-2 T V1.2 is a Dual Channel Subscriber Line Interface Concept (DuSLIC) device manufactured by Infineon Technologies, designed for wired communications. It integrates two subscriber line interface circuits (SLICs) and a codec within a single package to facilitate analog telephone line connectivity. The component supports standard PCM interfaces for digital signal processing integration. Key operational parameters include compliance with ITU-T Recommendation G.712 for voice transmission quality. The device incorporates features for DC feeding, AC transmission, ringing generation, and signaling supervision. It is part of the DuSLIC family, specifically version 1.2, which includes updates to register descriptions and power management capabilities compared to earlier revisions.

Telecom Feature Summary

Telecom Procurement Notes

Verify component authenticity through authorized Infineon distributors. Confirm RoHS status as the datasheet indicates non-compliance. Check for availability constraints as the product may be subject to limited supply or special ordering requirements. Ensure compatibility with existing system voltage levels and interface protocols before procurement.

Telecom Selection Notes

Select this component for applications requiring dual-channel subscriber line interfacing with integrated codec functionality. Consider the specific version 1.2 updates regarding register configurations and power dissipation characteristics. Evaluate thermal management requirements due to SLIC power dissipation during active and ringing modes. Ensure the host microcontroller supports the required PCM or IOM-2 interface protocols for control.

Telecom Part Context
