Product details
Overview
PEB 3324 HL V1.4 from Infineon Technologies is a 4-channel analog voice access IC optimized for residential gateways, VoIP routers, and ATAs. It integrates voice codec, DSP-based packet processing (AAL2/RTP), G.729/G.723.1/G.726 compression, T.38 fax relay, and line echo cancellation with up to 128 ms tail - all in a single LQFP-176 package.
For engineers reviewing the PEB 3324 HL V1.4 datasheet, PEB 3324 HL V1.4 pinout, PEB 3324 HL V1.4 application, or PEB 3324 HL V1.4 equivalent, this device delivers full VoIP voice processing capability without external RAM, supports ITU-T Q.552/G.712 compliance, and enables hardware reuse across multiple CPE platforms via SW/HW compatibility with other VINETIC variants.
Technical Context
The PEB 3324 HL V1.4 implements a dedicated voice DSP engine supporting simultaneous operation of four vocoders (e.g., G.729A + G.723.1 + G.726 + iLBC-in-prep) and real-time AAL2/RTP packetization with adaptive jitter buffer up to 200 ms. Its architecture includes integrated DTMF receiver, caller-ID generator/detector (FSK/DTMF), and programmable ringing (85 VRMS balanced).
It interfaces directly with Infineon SLIC devices (e.g., PEB 4266, PEB 4265-2) via standardized serial control and PCM/TDM buses, and performs GR-909-compliant line testing using Advanced Integrated Test and Diagnostic Functions (AITDF), eliminating need for external test circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel VoIP voice processing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 3324 EL | Same core functionality; differs in temperature grade (industrial vs. commercial) and minor errata fixes in V1.4 vs. V2.1 | Identical use in residential gateways; preferred where extended temperature range (-40°C to +85°C) is required | Select PEB 3324 EL for industrial environments; PEB 3324 HL suffices for standard CPE deployments |
| PEB 3332 EL | 8-channel variant with identical DSP engine, vocoder set, and SLIC interface - scaled channel count only | Used in higher-density IADs or PBX edge devices requiring >4 POTS lines | Choose PEB 3332 EL when expanding port count beyond four while retaining same firmware and layout reuse |
Compared with PEB 3324 EL and PEB 3332 EL, the PEB 3324 HL V1.4 offers optimal cost/performance balance for 4-line residential CPE, with verified firmware compatibility and reduced thermal load due to lower channel count - enabling smaller heatsink or fanless enclosure designs.

FAQ
Does PEB 3324 HL V1.4 require external SDRAM for operation?
No. The device integrates on-chip code RAM sufficient for firmware download and real-time voice processing tasks. External SDRAM is not required, reducing system cost and PCB area. This distinguishes it from earlier VINETIC generations like PEB 3320 E, which mandate external memory.
What SLIC devices are compatible with PEB 3324 HL V1.4?
It supports Infineon's full SLIC portfolio: PEB 4266 (SLIC-P), PEB 4265/4265-2 (SLIC-E/E2), PEB 4264/4264-2 (SLIC-S/S2), PEB 4365/4364 (TSLIC-E/S), PEB 4262 (SLIC-LCP), and PEF 4268 (SLIC-DC). Interface uses standard SPI-based control and analog TDM coupling.
Is T.38 fax relay implemented in hardware or firmware?
T.38 fax relay is implemented in dedicated hardware blocks within the VINETIC DSP engine, enabling zero-CPU-overhead, standards-compliant fax transmission. No host processor involvement is needed for demodulation, re-modulation, or protocol framing - meeting carrier-grade reliability requirements.
How does the AITDF feature simplify field deployment?
AITDF provides automated, standards-based (GR-909) line diagnostics - measuring loop resistance, capacitance, and insulation faults - without external test equipment. This enables remote provisioning, self-healing alerts, and reduced truck rolls during installation or maintenance of CPE devices.
