PEF 3394 HL V2.2

Telecom Overview

The Infineon PEF3394HLV2.2-G is a four-channel analog voice access integrated circuit belonging to the VINETIC family, designed for Customer Premises Equipment and Central Office applications. It integrates fully programmable CODEC functionality with embedded DSP capabilities for voice processing. The device supports multiple voice compression standards including G.728, G.723.1, G.729 A/B/E, G.726 ADPCM, and G.711. It features line echo cancellation supporting tails up to 128 ms and includes an integrated DTMF receiver and Caller-ID generator/detector. The component utilizes a PG-LQFP-176-2 package.

Telecom Feature Summary

• Integrates four channels of fully programmable CODEC with embedded DSP for voice processing
• Supports complex voice codecs such as G.728, G.723.1, and G.729 alongside standard G.711 and G.726
• Provides line echo cancellation with support for near and far-end echo tails up to 128 ms
• Includes ATM AAL2 and RTP packetization with jitter buffer capabilities for VoIP applications

Telecom Applications

• Residential Gateways and VoIP Routers
• Integrated Access Devices (IAD)
• Access Network equipment including DSLAMs and WLL systems
• PBX and VoIP-PBX systems

Telecom Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status as distribution availability varies by region. Ensure compatibility with required SLIC devices such as SLIC-DC or SLIC-E for complete telephony interface implementation.

Telecom Selection Notes

Select this component for designs requiring four simultaneous analog telephone lines with integrated packetization. Choose based on the need for complex codec support like G.729 and extensive echo cancellation. Verify that the system architecture accommodates the parallel or serial interface requirements typical of the VINETIC family.

Telecom Part Context

This part belongs to the Infineon VINETIC Enhanced Next Generation Analog Telephony Solutions family. It shares hardware and software compatibility with other members like the PEF3394E and PEF3394EL. The family provides scalable DSP performance ranging from pure TDM to full VoIP processing engines for various access network topologies.

Telecom Replacement Considerations

Consider the PEF3394E or PEF3394EL as pin-compatible alternatives within the same VINETIC family. Verify if the specific environmental or packaging variations in these variants meet the design requirements without necessitating schematic changes.
