Product details
Overview
PEB 3342 HT V2.2 from Infineon Technologies is a single-channel VoIP processor for analog telephone adapters (ATA), integrating G.711/G.726/G.723.1/G.729A/B/E/iLBC codecs, 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 supports PCM host interface, DTMF generation/reception, and caller ID signaling. Used in compact ATA designs requiring full-featured voice processing without integrated SLIC.
For engineers reviewing the PEB 3342 HT V2.2 datasheet, PEB 3342 HT V2.2 pinout, PEB 3342 HT V2.2 application, or PEB 3342 HT V2.2 equivalent, key selection criteria include SLIC interface compatibility, multi-codec support across G.7xx and iLBC standards, real-time echo cancellation depth, jitter buffer adaptivity, and PCM bus timing alignment with host controllers.
Technical Context
The PEB 3342 HT V2.2 implements a dedicated VoIP signal processing engine with hardware-accelerated codec execution and embedded DSP resources for concurrent voice path handling. Its architecture includes a programmable PCM interface supporting master/slave modes, configurable frame sync polarity, and 8/16-bit data width - enabling direct connection to ARM or MIPS-based host processors.
It relies on external SLIC devices for line feeding, ringing, and loop supervision, communicating via dedicated control registers and status signals. All voice processing functions - including VAD, AGC, CID detection/generation, and T.38 fax relay - are firmware-controlled and runtime-configurable through Infineon's standardized TAPI driver layer.
