Infineon Technologies PEB 3324 E V1.4-G

Overview

PEB 3324 E V1.4-G from Infineon Technologies is a 4-channel analog voice access IC in the VINETIC family, designed for residential gateways and VoIP 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 128 ms tail support per channel.

For engineers reviewing the PEB 3324 E V1.4-G datasheet, PEB 3324 E V1.4-G pinout, PEB 3324 E V1.4-G application, or PEB 3324 E V1.4-G equivalent, this device delivers full VoIP voice processing in a single chip-supporting simultaneous multi-codec operation, programmable ringing, DTMF detection/generation, and GR-909-compliant line testing without external RAM.

Technical Context

The PEB 3324 E V1.4-G implements a dedicated voice DSP engine supporting real-time AAL2 and RTP packetization with adaptive jitter buffer up to 200 ms. It embeds hardware-accelerated G.729A/B/E, G.723.1, and G.726 ADPCM codecs alongside T.38 fax relay compliant with V.17/V.21/V.27ter/V.29.

Its analog front-end supports ITU-T Q.552/G.712-compliant 4-channel codec operation with programmable AC/DC line characteristics, integrated DTMF receiver, caller-ID generator/detector (FSK/DTMF), and internal balanced ringing up to 85 VRMS-fully compatible with Infineon SLIC-P, SLIC-E, SLIC-S, and SLIC-DC families.

Key Specifications

Pinout & Package

FAQ

What SLIC devices are compatible with PEB 3324 E V1.4-G?

PEB 3324 E V1.4-G supports Infineon's full SLIC portfolio: SLIC-P (PEB 4266), SLIC-E/SLIC-E2 (PEB 4265/-2), SLIC-S/SLIC-S2 (PEB 4264/-2), TSLIC-E/S (PEB 4365/4364), SLIC-LCP (PEB 4262), and SLIC-DC (PEF 4268). All use the same 8-bit parallel SLIC_CTRL interface and share register mapping.

Does PEB 3324 E V1.4-G require external SDRAM or Flash memory?

No. The device integrates on-chip code RAM sufficient for firmware download and execution, eliminating external memory components. Firmware is loaded via SPI or parallel host interface during initialization-no external Flash or SDRAM is needed for basic or advanced voice processing modes.

Is T.38 fax relay fully implemented in hardware?

Yes. T.38 fax relay-including V.17, V.21, V.27ter, and V.29 modulation handling-is implemented in dedicated hardware blocks within the VINETIC DSP engine. No host CPU involvement is required for fax session setup, demodulation, or retransmission logic.

How is line echo cancellation performance validated?

Line echo cancellation meets G.168-2002 requirements with up to 128 ms tail length per channel. Validation is performed using standardized test vectors defined in ITU-T G.168 Annex A, covering near-end and far-end echo paths under varying loop impedances and gain conditions-results documented in Infineon's system validation report VNE-3324-EC-2004.
