Product details
Overview
PEF 3314 E V2.1 from Infineon Technologies is a 4-channel analog voice access IC (VINETIC family) designed for residential gateways, VoIP routers, and ATAs. It integrates voice codec, DSP-based packet processing (AAL2/RTP), G.726 ADPCM, T.38 fax relay, and line echo cancellation with up to 128 ms tail. Supports programmable AC/DC line characteristics and internal balanced ringing up to 85 VRMS.
For engineers reviewing the PEF 3314 E V2.1 datasheet, PEF 3314 E V2.1 pinout, PEF 3314 E V2.1 application in VoIP CPE, or PEF 3314 E V2.1 equivalent for multi-channel voice gateway design, this page delivers verified functional identity, real-time voice processing capabilities, SLIC interface compatibility, and confirmed hardware/software co-design constraints.
Technical Context
The PEF 3314 E V2.1 implements a dedicated voice-over-packet engine supporting both ATM AAL2 and RTP packetization with adaptive jitter buffer up to 200 ms. Its integrated DSP handles simultaneous voice coders (up to 4), T.38 fax relay (V.17/V.21/V.27ter/V.29), and line echo cancellation compliant with G.168-2002.
It features full ITU-T Q.552/G.712/LSSGR compliance, programmable DTMF receiver and caller-ID generator/detector (FSK/DTMF), and supports external SLICs including SLIC-P, SLIC-E, SLIC-S, TSLIC-E, TSLIC-S, SLIC-LCP, and SLIC-DC - enabling flexible line-side interface configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel voice-over-packet applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF 3314 HL | Same silicon, higher-grade screening (industrial temp range −40°C to +85°C vs. commercial 0°C to +70°C) | Required for outdoor DSLAM or street cabinet deployments | Select when extended temperature operation or longer lifecycle commitment is mandated |
| PEB 3324 E | 4-channel variant with full G.723.1/G.729 codec support and larger internal RAM; no iLBC prep | Needed for carrier-grade VoIP with narrowband compression and high-density call handling | Choose when G.729A/B deployment or >4 simultaneous VoCoders are required |
Compared with PEF 3314 HL, the V2.1 version trades industrial temperature tolerance for lower cost and power; compared with PEB 3324 E, it omits complex vocoders but retains identical SLIC control, echo cancellation, and T.38 capability - making it optimal for cost-sensitive residential CPE where G.726 suffices.

FAQ
Does PEF 3314 E V2.1 support G.729 or G.723.1 vocoders?
No. Per Infineon's Product Brief and V2.1 datasheet, PEF 3314 E supports only G.726 ADPCM (16/24/32/40 kbit/s) and G.711. G.723.1 and G.729 are supported in PEB 3324 E and PEF 3394 E variants, not in this version.
What SLIC devices are electrically and logically compatible with PEF 3314 E V2.1?
PEF 3314 E V2.1 supports SLIC-P (PEB 4266), SLIC-E (PEB 4265), SLIC-S (PEB 4264), TSLIC-E (PEB 4365), TSLIC-S (PEB 4364), SLIC-LCP (PEB 4262), and SLIC-DC (PEF 4268). All use the same 3-wire serial control interface and register mapping.
Is external SDRAM or Flash required for PEF 3314 E V2.1 operation?
No. PEF 3314 E V2.1 contains integrated code RAM for firmware download and does not require external memory. Unlike VINETIC-4 VIP or VINETIC-4 M, it has no external memory bus interface.
Can PEF 3314 E V2.1 generate and detect caller-ID using both FSK and DTMF formats?
Yes. The device integrates a dual-mode caller-ID generator and detector supporting both Bellcore FSK (1200/2200 Hz) and DTMF (tone pair) formats on all four channels, with configurable polarity reversal and message buffering.
