Product details
Overview
PEB 3320 HT V2.2 from Infineon Technologies is a single-channel VoIP processor with integrated SLIC-DC and CODEC, supporting G.711/G.726 ADPCM/iLBC/G.723.1/G.729A/B/E codecs, T.38 fax relay, adaptive jitter buffer, and line echo cancellation up to 128 ms - deployed in compact FXS VoIP adapters and xDSL home gateways.
For engineers reviewing the PEB 3320 HT V2.2 datasheet, PEB 3320 HT V2.2 pinout, PEB 3320 HT V2.2 application, or PEB 3320 HT V2.2 equivalent, key selection criteria include SLIC integration level, PCM interface compatibility, codec concurrency (4-channel), echo cancellation window depth, and PG-LBGA-144 package thermal and routing constraints.
Technical Context
The PEB 3320 HT V2.2 implements a dedicated VoIP signal processing architecture with hardware-accelerated voice coding/decoding engines for G.729A/B/E and G.723.1, plus real-time T.38 fax relay handling. It integrates a full SLIC-DC controller with DC feed, ringing generation, and line monitoring functions.
Its PCM interface supports master/slave mode with 8/16-bit data width and programmable frame sync timing, enabling direct connection to host network controllers or DSPs. The device uses an internal ARM7TDMI-based core for protocol stack execution and peripheral management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VoIP Codecs | G.711, G.726 ADPCM, iLBC, G.723.1, G.729A/B/E - enables interoperability across PSTN, legacy PBX, and SIP trunking environments |
| T.38 Fax Relay | Full hardware-accelerated support - eliminates need for external fax DSP or software-based T.38 stacks |
| Line Echo Cancellation | Up to 128 ms adaptive window - meets ITU-T G.168 requirements for hybrid echo suppression in analog line interfaces |
| Jitter Buffer | Adaptive algorithm with dynamic depth control - maintains voice continuity under variable packet delay variation in broadband access networks |
| SLIC Integration | Integrated SLIC-DC V1.2 - provides complete BORSCHT functions (Battery, Overvoltage, Ringing, Supervision, Coding, Hybrid, Test) without external SLIC IC |
| PCM Interface | Master/slave configurable, 8/16-bit, frame-sync programmable - ensures plug-and-play connectivity with common network processors and SoCs |
| Package | PG-LBGA-144 (10 mm × 10 mm, 0.8 mm pitch) - supports high-density PCB layout and thermal dissipation in space-constrained CPE enclosures |
Pinout & Package
PEB 3320 HT V2.2 is housed in a 144-pin Low-Profile Ball Grid Array (PG-LBGA-144) package with 0.8 mm ball pitch and 10 mm × 10 mm body size. Thermal pad on underside requires soldered ground connection for reliable operation at full codec load.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO / VDDA / VDDD | Power supply domains | Separate 3.3 V I/O, 3.3 V analog, and 1.8 V digital rails - enable noise isolation between CODEC, SLIC, and processor subsystems |
| PCM_CLK / PCM_FS / PCM_DI / PCM_DO | PCM serial interface | Configurable master/slave timing - allows flexible clock sourcing from host or internal oscillator for system-level synchronization |
| SLIC_VP / SLIC_VN / SLIC_TIP / SLIC_RING | SLIC line interface terminals | Direct connection to telephone line pair - supports FXS termination with programmable loop current (20–45 mA) and ringing voltage (75 Vrms) |
| RESET_N / BOOT_MODE[1:0] | Initialization control | Determines boot source (internal ROM vs. external SPI flash) and reset sequencing - critical for firmware recovery and field-upgrade robustness |
| GPIO[7:0] | General-purpose I/O | Programmable as interrupt inputs or status outputs - used for DTMF detection flags, CID signaling, or external relay control |
Key Features
| Feature | Design Value |
|---|---|
| Single-chip FXS VoIP engine | Integrates SLIC-DC, CODEC, and VoIP processor - reduces BOM count by ≥3 discrete ICs and eliminates inter-IC signal integrity risks |
| 4-concurrent voice channels | Hardware-supported codec concurrency - enables multi-line operation or background fax/voice coexistence without CPU overload |
| ARM7TDMI host processor | Embedded 60 MHz core with 32 KB SRAM - runs full VoIP stack (SIP, RTP, RTCP, T.38) and application logic without external MCU |
| Linux/VxWorks driver support | OS-agnostic driver layer with TAPI abstraction - accelerates time-to-market for embedded VoIP gateway development |
| Worldwide line parameter programming | Configurable SLIC settings per regional telephony standard (ETSI, FCC, ARIB, ANATEL) - enables single-hardware global deployment |
Applications
| VoIP Analog Adapter | SOHO IP PBX |
|---|---|
Use Scenario: Compact desktop device connecting one analog phone to VoIP service via Ethernet or Wi-Fi. IC Role / Device Role / Timing Role: Full VoIP endpoint: handles codec, SLIC, signaling, and packetization - operates as standalone SIP UA. Use Value: Eliminates need for external MCU or SLIC, reducing footprint to < 50 cm² while maintaining G.729A compliance and echo-free call quality. |
Use Scenario: Small-office telephone system supporting 2–4 analog extensions and PSTN backup via FXO gateway. IC Role / Device Role / Timing Role: Central voice processing unit: manages multiple concurrent calls, DTMF/CID, and T.38 fax over shared PCM bus. Use Value: Enables dual-channel operation with independent echo cancellation per line - supports simultaneous voice/fax without resource contention. |
| xDSL Home Gateway | DECT VoIP Base Station |
Use Scenario: Integrated DSL modem/router with built-in FXS port for analog phone support alongside broadband data. IC Role / Device Role / Timing Role: Voice subsystem co-processor: offloads VoIP processing from main SoC via PCM interface - isolates real-time voice latency from data traffic. Use Value: Maintains sub-150 ms end-to-end latency even during heavy TCP throughput - verified per ITU-T G.114 for conversational voice. |
Use Scenario: Cordless base station linking DECT handsets to VoIP network, requiring low-power standby and fast call setup. IC Role / Device Role / Timing Role: Voice path controller: manages codec negotiation, echo cancellation, and power-gated SLIC during idle periods. Use Value: Achieves < 25 mW standby power via selective clock gating - extends base station battery life in portable configurations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar VoIP processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 3340 HT V2.2 | Dual-channel version with identical SLIC-DC and codec set - shares same firmware and pinout but doubles concurrent call capacity | Targeted at 2-FXS gateway designs; requires additional PCB area and power budget for second channel | Select when scaling from single- to dual-line CPE without redesigning firmware or driver stack |
| PEB 3332 HT V2.2 | No integrated SLIC; requires external SLIC-DC (e.g., PEB 3322) - separates analog and digital domains for higher ESD immunity | Suitable for designs needing enhanced surge protection or custom SLIC tuning (e.g., industrial FXO/FXS hybrids) | Choose where SLIC isolation, extended temperature range, or differential line sensing is mandatory |
Compared with PEB 3340 HT V2.2, the PEB 3320 offers lower power and smaller footprint for single-line use; versus PEB 3332 HT V2.2, it trades external SLIC flexibility for reduced component count and simplified layout - making it optimal for cost-sensitive, space-constrained FXS endpoints.

FAQ
What operating systems does the PEB 3320 HT V2.2 support?
Infineon provides certified Linux and VxWorks drivers for the PEB 3320 HT V2.2, both built on an OS-agnostic firmware layer. The driver includes TAPI abstraction and supports kernel versions 2.4.x through 2.6.x. No Windows or RTOS drivers were released by Infineon for this device.
Does the PEB 3320 HT V2.2 require an external crystal?
Yes - the device requires a 13.0 MHz fundamental-mode crystal connected to XIN/XOUT pins for the internal PLL, which generates all required clocks (including 12.288 MHz for PCM and 60 MHz for the ARM7TDMI core). No internal RC oscillator is provided for production use.
Can the SLIC-DC be configured for FXO operation?
No - the integrated SLIC-DC in PEB 3320 HT V2.2 is strictly FXS-oriented (line feeding, ringing, supervision). FXO functionality requires external components and is not supported by the on-die SLIC; Infineon recommends PEB 3332 + PEB 3322 for FXO-capable designs.
Is T.38 fax relay implemented in hardware or firmware?
T.38 fax relay is fully hardware-accelerated within the PEB 3320 HT V2.2's VoIP engine - including real-time demodulation, packetization, redundancy, and retransmission logic. Firmware handles only session control (SIP INFO, T.38 capability negotiation), not signal processing.
