PEB 33321 EL V2.2-G

Telecom Overview

The PEB 33321 EL V2.2-G is a VINETIC®-1CPE VoIP processor designed for Customer Premises Equipment (CPE). It integrates a Voice over IP DSP, RAM/ROM, and a single-channel analog CODEC with SLIC interfaces. The device supports up to two simultaneous VoIP channels using G.729A/B/E or G.723.1 codecs, alongside four channels of G.711, G.726 ADPCM, or iLBC. It features window-based Line Echo Cancellation (WLEC) up to 128 ms, adaptive jitter buffering, and T.38 fax relay capabilities. The component interfaces via SPI, SCI, or parallel modes and connects to external SLIC-DC or SLIC-E circuits.

Telecom Feature Summary

• Integrates a single-channel analog CODEC with dedicated interfaces for connecting to external Subscriber Line Interface Circuits (SLICs).
• Provides scalable VoIP processing power supporting multiple voice coding standards including G.729, G.723.1, G.711, and iLBC.
• Includes advanced signal processing functions such as window-based line echo cancellation, adaptive jitter buffering, and caller ID detection.
• Offers flexible host connectivity through serial (SPI, SCI) and parallel (Intel/Motorola mode) digital interfaces.

Telecom Applications

• VoIP home gateways and xDSL broadband access devices
• Small and Medium Enterprise (SME) VoIP routers
• SOHO IP PBX systems
• WiMax and xPON Integrated Access Devices (IAD)

Telecom Procurement Notes

Verify the specific revision suffix against current Infineon documentation to ensure compatibility with required firmware versions. Confirm that the package type matches the target PCB footprint requirements. Check for end-of-life status or obsolescence notices prior to finalizing design-in decisions, as this component belongs to an older product generation.

Telecom Selection Notes

Select this model when a single analog telephone interface is required alongside robust VoIP processing capabilities. It is suitable for designs needing support for both FXS and FXO operations via external DAA integration. Choose this part over the PLUS version if integrated SLIC functionality is not desired, or over the ATA version if higher channel capacity and longer echo cancellation are necessary.

Telecom Part Context

This component belongs to the VINETIC®-CPE family, which includes the 2CPE, 1ATA, 2ATA, CL, and 0 variants. These devices share hardware pin-compatibility and software compatibility, allowing for scalable system designs. The VINETIC®-CPE series serves as a complete system solution, providing the necessary DSP firmware and device drivers for Linux and VxWorks operating systems.
