Product details
Overview
PEB 33322 EL V2.2-G from Infineon Technologies is a single-channel VoIP processor (VINETIC®-0/-CL family) without integrated analog CODEC or SLIC, designed as the core voice processing engine in CPE systems. It supports G.711, G.726 ADPCM, G.723.1, G.729A/B/E, iLBC codecs and T.38 fax relay, implements adaptive jitter buffer and up to 128 ms line echo cancellation, and interfaces via PCM to external CODEC/SLIC - deployed in xDSL home gateways and SOHO IP PBXs.
For engineers reviewing the PEB 33322 EL V2.2-G datasheet, PEB 33322 EL V2.2-G pinout, PEB 33322 EL V2.2-G application, or PEB 33322 EL V2.2-G equivalent, this page delivers verified technical context, package mapping, functional role in VoIP signal path, and validated alternatives for analog telephony system design.
Technical Context
The PEB 33322 operates as a standalone VoIP protocol and voice processing engine, requiring external analog front-end components (e.g., SLIC-DC V1.2 or SLIC-E V2.1) via standard PCM and control interfaces. It executes real-time voice coding/decoding, packetization (RTP), and network-side voice processing including VAD, AGC, DTMF/CID generation/reception, and T.38 fax relay.
Its architecture supports software-defined configuration of codec selection, echo cancellation window size (up to 128 ms), and jitter buffer adaptation - all managed through host-controlled firmware APIs. The device is fully software-compatible with other VINETIC®-CPE family members, enabling scalable migration across 1- to 2-channel designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VoIP Codec Support | G.711 μ-law/A-law, G.726 ADPCM, G.723.1, G.729A/B/E, iLBC - enables interoperability with global PSTN and VoIP networks. |
| T.38 Fax Relay | Full T.38-compliant fax over IP relay - eliminates analog fax machine compatibility issues in packet networks. |
| Line Echo Cancellation | Up to 128 ms window-based LEC - suppresses hybrid echo in FXS/FXO line interfaces without external DSP. |

| PCM_CLK / PCM_FS / PCM_DI / PCM_DO | PCM serial interface | Master/slave configurable synchronous interface for bidirectional voice data transfer with external CODEC/SLIC. |
| RESET_N / IRQ_N | System control signals | Active-low reset and interrupt request - synchronize firmware initialization and event-driven host communication. |
| I2C_SCL / I2C_SDA | Configuration bus | Two-wire I²C interface for loading runtime parameters, calibration data, and SLIC control registers. |
| GPIO[7:0] | General-purpose I/O | Eight programmable pins for status indication, button sensing, LED control, or auxiliary signaling in CPE hardware. |
Key Features
| Feature | Design Value |
|---|---|
| Software compatibility across VINETIC®-CPE family | Enables reuse of driver stack and TAPI layer across PEB 33322, PEB 33321, PEB 3332, and PEB 3331 - reduces firmware development effort by >40%. |
| OS-independent driver support | Pre-integrated Linux and VxWorks drivers with abstracted HAL - accelerates porting to custom RTOS or bare-metal environments. |

| VoIP Analog Adapter (ATA) | DECT VoIP Base Station |
Use Scenario: Single-port ATA converting PSTN line to SIP trunk for legacy phone integration. IC Role / Device Role / Timing Role: Standalone VoIP engine interfacing to SLIC-DC V1.2 for line feeding and to host MCU for SIP stack - uses PCM for voice, I²C for configuration. Use Value: Supports G.729A compression at 8 kbps - extends bandwidth efficiency for low-bandwidth DSL connections without sacrificing MOS ≥ 4.0. |
Use Scenario: DECT base station with dual-mode (DECT + VoIP) operation, serving up to 6 handsets. IC Role / Device Role / Timing Role: Dedicated voice path processor offloading codec, echo cancellation, and fax relay from main DECT SoC - clocked synchronously to DECT baseband timer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VoIP processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 33321 EL V2.2-G | Identical core VoIP engine but includes integrated single-channel SLIC-DC - eliminates need for external SLIC in cost-sensitive designs. | Targeted at compact single-FXS adapters where board space is constrained and SLIC integration reduces component count. | Select when SLIC integration is preferred and analog line interface is limited to one FXS port. |
| PEB 3332 EL V2.2-G | Dual-channel version with identical VoIP processing capability plus second PCM interface - supports two independent voice paths. | Required for multi-line devices such as 2-port ATAs, VoIP routers with redundant FXS/FXO, or IP PBXs with >1 concurrent call requirement. | Select when system requires concurrent dual-call handling or future scalability to two analog lines. |
Compared with PEB 33321 (integrated SLIC) and PEB 3332 (dual-channel), the PEB 33322 offers optimal flexibility for designs using external SLICs - preserving layout modularity, thermal separation, and vendor choice while retaining full firmware compatibility and feature parity.

FAQ
Does PEB 33322 EL V2.2-G include an integrated SLIC or CODEC?
No. The PEB 33322 EL V2.2-G is a pure VoIP processor (VINETIC®-0/-CL variant) with no integrated SLIC or analog CODEC. It requires external SLIC-DC V1.2 or SLIC-E V2.1 and a separate CODEC, connected via standard PCM and I²C interfaces as defined in Infineon's VINETIC®-CPE hardware reference design.
What operating systems are supported by the official driver package?
Infineon provides production-ready, pre-validated drivers for Linux and VxWorks, both built on an OS-agnostic hardware abstraction layer (HAL). The HAL enables straightforward porting to other real-time OSes like FreeRTOS or ThreadX, and documentation includes register-level initialization sequences for bare-metal implementations.
Is the PEB 33322 EL V2.2-G pin-compatible with other VINETIC®-CPE devices?
Yes - it shares identical pinout with PEB 33321 (VINETIC®-1PLUS) in the PG-LBGA-144 package. However, it is not pin-compatible with PEB 3332/PEF 3332 (TQFP-100) or PEB 3331/PEF 3331 (TQFP-64), which use different packages and I/O mappings despite software compatibility.
What is the maximum number of concurrent voice calls supported?
The PEB 33322 EL V2.2-G supports one full-duplex voice channel. Its processing resources are allocated for single-call operation including G.729A encoding/decoding, 128 ms echo cancellation, adaptive jitter buffering, and T.38 fax relay - confirmed in Infineon's VINETIC®-CPE Product Overview Rev. 1.0 (2006-10-09), Section 2.4.1.
