PEB 33322 EL V2.2-G

Telecom Overview

The Infineon PEB33322ELV2.2-G is a VINETIC®-CPE VoIP processor designed for Customer Premises Equipment (CPE). It integrates a 2-channel analog CODEC and supports two FXS interfaces via external SLICs. The device handles voice coding including G.711, G.726 ADPCM, G.723.1, G.729A/B/E, iLBC, and T.38 Fax relay. It features up to 4 simultaneous VoIP channels with adaptive jitter buffering and window-based line echo cancellation (WLEC) supporting up to 128 ms tail length. Hardware interfaces include SPI, SCI, and parallel modes (Intel/Motorola), alongside GPIO capabilities.

Telecom Feature Summary

• Integrates dual-channel analog CODEC functionality for voice signal processing
• Supports multiple industry-standard voice compression algorithms and fax relay protocols
• Provides scalable VoIP channel capacity with advanced echo cancellation capabilities
• Offers flexible host connectivity through serial and parallel interface options

Telecom Applications

• VoIP home gateways and broadband IADs
• Small Office/Home Office (SOHO) IP PBX systems
• Portable wireless VoIP routers and ATA devices

Telecom Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific revision level matches system requirements. Check for end-of-life status as this part may be discontinued. Ensure compatibility with required firmware versions and operating system drivers before integration into final designs.

Telecom Selection Notes

Select this model when dual analog telephone lines are required within a single integrated solution. Compare against the PEB33321 for single-channel needs or the PEB3332 if SLIC integration is not needed. Consider power supply constraints and available package types such as PG-TQFP-100 or PG-LBGA-144 based on board space limitations.

Telecom Part Context

This component belongs to the VINETIC®-CPE family of VoIP processors from Infineon Technologies. It is part of a scalable series that includes variants like the VINETIC®-PLUS, -ATA, and -CL/-0. These devices share software compatibility and hardware pin-out similarities to facilitate product differentiation across various CPE market segments.

Telecom Replacement Considerations

Direct replacements within the same family include the PEB33321 for single-channel applications. For systems requiring integrated SLIC functionality, consider the PEB33322ELV2.2-G's sibling parts in the VINETIC®-PLUS series. Verify pin compatibility and firmware support when substituting.
