Product details
Overview
PEB 3332 HT V2.2 from Infineon Technologies is a single-channel VoIP processor for Customer Premises Equipment, integrating G.711/G.726/G.723.1/G.729A/B/E/iLBC codec support, T.38 fax relay, adaptive jitter buffer, and line echo cancellation up to 128 ms. It interfaces with external SLIC-DC V1.2 or SLIC-E V2.1 and targets analog telephone adapters (ATA) in xDSL gateways and SOHO IP PBX systems.
For engineers reviewing the PEB 3332 HT V2.2 datasheet, PEB 3332 HT V2.2 pinout, PEB 3332 HT V2.2 application, or PEB 3332 HT V2.2 equivalent, key selection criteria include PCM interface compatibility, SLIC driver requirements, voice coder channel count, echo cancellation depth, and firmware-supported telephony features like DTMF/CID and AGC.
Technical Context
The PEB 3332 HT V2.2 implements a dedicated VoIP signal processing engine with hardware-accelerated voice coding/decoding across six ITU-T standards and T.38 fax relay. Its architecture includes integrated PCM interface logic, real-time jitter buffer management, and window-based line echo canceller with 128 ms tail length.
It operates as a host-controlled peripheral requiring external SLIC for analog line interface, supporting both FXS and FXO configurations via SLIC-DC V1.2 or SLIC-E V2.1. Firmware-driven telephony functions include VAD, AGC, CID receive/send, and DTMF detection/generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| G.729A/B/E Support | 2-channel concurrent operation; enables dual-line VoIP ATA with full-compliance narrowband speech coding. |
| Jitter Buffer | Adaptive algorithm; dynamically adjusts buffer depth to compensate for network packet delay variation in real time. |
| Line Echo Cancellation | Up to 128 ms tail length; suppresses hybrid echo in analog telephone interfaces without requiring external DSP resources. |
| PCM Interface | Standard 8-bit/16-bit μ-law/A-law synchronous serial; directly connects to host controller or baseband processor for voice data exchange. |
| T.38 Fax Relay | Full protocol stack implementation; allows lossless fax transmission over IP networks without demodulation/re-modulation. |
| Dual DTMF/CID | Simultaneous DTMF tone generation/reception and caller ID signaling (FSK/DTMF); supports legacy PSTN feature interoperability. |
Pinout & Package
PEB 3332 HT V2.2 is housed in a PG-TQFP-100 package (14 × 14 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad for VoIP processor thermal management in compact CPE designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PCM_CLK | PCM Interface Clock | Synchronous timing reference for 8/16-bit PCM data transfer; configurable master/slave mode. |
| PCM_FS | PCM Frame Sync | Indicates start of PCM frame; aligns voice sample boundaries between PEB 3332 and host controller. |
| PCM_DI | PCM Data Input | Receives digitized voice samples from external CODEC or SLIC interface; supports μ-law/A-law formats. |
| PCM_DO | PCM Data Output | Transmits processed PCM stream to external DAC or SLIC; synchronized to PCM_CLK/PCM_FS. |
| SLIC_CS | SLIC Chip Select | Active-low enable for SPI communication with external SLIC-DC V1.2 or SLIC-E V2.1 devices. |
| INT_N | Interrupt Output | Open-drain signal indicating event completion (e.g., DTMF detected, CID received, buffer underrun). |
Key Features
| Feature | Design Value |
|---|---|
| G.723.1 & G.729A/B/E Coding | Hardware-accelerated dual-channel encoding/decoding reduces host CPU load and ensures deterministic real-time latency. |
| Adaptive Jitter Buffer | Self-tuning buffer depth minimizes packet loss impact while maintaining end-to-end delay under 150 ms for VoIP compliance. |
| 128 ms Line Echo Cancellation | Eliminates need for external echo canceller IC in FXS/FXO designs, simplifying BOM and PCB layout. |
| Firmware-Based Telephony Stack | Pre-integrated TAPI-compatible layer enables rapid development of call control, DTMF, CID, and AGC without low-level driver coding. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VoIP processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 3331 HT V2.2 | Single-channel only; same firmware and pinout but reduced G.729/G.723.1 concurrency (1 vs 2 channels). | Targeted at cost-sensitive single-line ATA; lacks dual-call capability required for multi-line gateways. | Select when only one concurrent VoIP call is needed and board space is constrained. |
| PEB 3342 HT V2.2 | Two-channel VINETIC®-2ATA variant; identical core but adds second PCM interface and dual-SLIC support. | Designed for dual-FXS/FXO gateways requiring independent echo cancellation per line. | Choose for dual-line systems needing parallel voice processing without host CPU overhead. |
Compared with PEB 3331 HT V2.2, the PEB 3332 HT V2.2 delivers double voice channel capacity within the same footprint; versus PEB 3342 HT V2.2, it trades dual-line autonomy for lower power and simpler SLIC interface routing in single-line deployments.

FAQ
What SLIC devices are compatible with PEB 3332 HT V2.2?
PEB 3332 HT V2.2 supports SLIC-DC V1.2 and SLIC-E V2.1 devices via its SPI interface and SLIC_CS control pin. Compatibility is verified through Infineon's reference designs for FXS/FXO configurations, including PEB 3210 and PEB 3220 SLICs. No other SLIC families are supported due to register map and timing constraints.
Does PEB 3332 HT V2.2 require external memory for firmware execution?
No - PEB 3332 HT V2.2 contains on-chip ROM storing boot code and essential firmware modules. External Flash (e.g., SPI NOR) is required only for field-upgradable application layers and telephony parameter tables, not for basic operation.
Can PEB 3332 HT V2.2 operate in standalone mode without a host processor?
No - it requires an external host controller (ARM/MIPS-based SoC or MCU) to manage SIP stack, network interface, and system-level call control. The PEB 3332 handles only voice signal processing, not network protocol stacks or user interface functions.
Is Linux driver support available for PEB 3332 HT V2.2?
Yes - Infineon provides a production-ready Linux kernel driver (v2.6.x compatible) with TAPI abstraction layer, documented in Application Note AN2345. The driver supports PCM interface configuration, interrupt handling, and firmware update via sysfs interface.
