Product details
Overview
PEB 3324 E V1.4 from Infineon Technologies is a 4-channel analog voice access IC in the VINETIC family, designed for residential gateways and VoIP ATAs. It integrates TDM codec, DSP-based voice compression (G.726, G.729A/B/E), T.38 fax relay, and line echo cancellation with up to 128 ms tail-meeting ITU-T G.168-2002 and Q.552 requirements.
For engineers reviewing the PEB 3324 E V1.4 datasheet, PEB 3324 E V1.4 pinout, PEB 3324 E V1.4 application, or PEB 3324 E V1.4 equivalent, key selection criteria include integrated AAL2/RTP packetization, programmable ringing (85 VRMS balanced), GR-909-compliant line testing, and hardware/software compatibility across VINETIC-4 variants.
Technical Context
The PEB 3324 E V1.4 implements a dedicated voice-processing DSP core supporting simultaneous encoding/decoding of four voice channels. It delivers full AAL2 and RTP packetization with adaptive jitter buffer (up to 200 ms), and embeds T.38 fax relay with V.17/V.21/V.27ter/V.29 modulation support.
Its analog front-end complies with ITU-T G.712 and LSSGR specifications, features programmable AC/DC line characteristics independent of regional standards, and integrates DTMF receiver, caller-ID generator/detector (FSK/DTMF), and metering pulse generation (2.5 VRMS at 200 Ω).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel voice processing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 3324 HL | Same pinout and firmware, but higher temperature grade (–40°C to +105°C vs. –20°C to +70°C) | Required for industrial or outdoor CPE deployments with extended thermal range | Select when operating ambient exceeds 70°C or requires extended reliability qualification |
| PEB 3324 EL2 | Includes updated firmware version (V2.1+), adds iLBC readiness and enhanced AITDF diagnostics | Suitable for new designs targeting royalty-free vocoder adoption or advanced line health monitoring | Select for greenfield VoIP platforms requiring future-proofing beyond G.729 licensing constraints |

FAQ
Does PEB 3324 E V1.4 require external SDRAM or Flash memory?
No. The device integrates 128 KB of on-chip code RAM for firmware download and execution, eliminating external memory components. Firmware is loaded via JTAG or serial interface at boot, and all voice processing-including G.729 encoding-is performed in internal DSP resources without off-chip dependencies.
What SLIC devices are compatible with PEB 3324 E V1.4?
It natively supports Infineon's SLIC-P (PEB 4266), SLIC-E (PEB 4265), SLIC-E2 (PEB 4265-2), SLIC-S (PEB 4264), SLIC-S2 (PEB 4264-2), TSLIC-E (PEB 4365), TSLIC-S (PEB 4364), SLIC-LCP (PEB 4262), and SLIC-DC (PEF 4268). Control is handled through the 4-bit SLIC_CTRL bus with precise timing for ringing and hook-state transitions.
Is T.38 Fax Relay fully implemented in hardware or firmware?
T.38 Fax Relay is implemented in the on-chip DSP with dedicated firmware modules for V.17, V.21, V.27ter, and V.29 modulation schemes. No host CPU involvement is required-fax data is packetized, error-corrected, and retransmitted autonomously using the integrated AAL2/RTP engine and jitter buffer.
How is line echo cancellation calibrated for different loop lengths?
Echo cancellation uses adaptive NLMS algorithms with configurable tail length up to 128 ms. Calibration occurs automatically during call setup using built-in test tones and real-time convergence monitoring. Configuration registers allow fine-tuning of convergence speed and residual echo suppression level per channel based on measured loop impedance and distance.
