Product details
Overview
PEB3264FV1.4 from Infineon Technologies is a dual-channel POTS line interface IC (SLIC) with integrated codec-filter, supporting VoIP/VoDSL telephony in CPE and access network equipment. It delivers 3.3 V operation, programmable ring voltage up to 170 V (balanced), DTMF detection, 8 ms line echo cancellation, and V.90 modem transmission capability.
For engineers reviewing the PEB3264FV1.4 datasheet, PEB3264FV1.4 pinout, PEB3264FV1.4 application, or PEB3264FV1.4 equivalent, this device serves as a fully programmable, low-power dual-channel subscriber line interface for voice-over-packet systems requiring lifeline support, remote line testing, and integrated tone generation.
Technical Context
The PEB3264FV1.4 implements a two-channel SLIC + codec-filter architecture with serial controller interface and PCM/IOM-2 digital audio bus. It integrates analog front-end functions including DC feeding control, AC impedance synthesis, and balanced/unbalanced ringing generation without external relays.
Its programmability covers all AC/DC parameters-loop current (32 mA), longitudinal balance (>53 dB), ring-trip threshold, and loop length compensation-enabling single-hardware deployment across global telephony standards (ITU-T G.992.x, G.994.1, GR-909).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel POTS interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB3265F v1.3 | Same pinout and register map; adds enhanced feature set including V.90 modem tone detection and improved longitudinal balance (55 dB vs. 53 dB) | Required for V.90 modem certification in North America; not needed for basic VoIP voice-only use | Select when modem interoperability testing or extended line diagnostics are mandatory |
| SLICOFI-2S2 | Identical functional block diagram but uses P-TQFP-64-1 (12 × 12 mm) package with different thermal pad layout | Suitable for space-constrained designs where footprint reduction outweighs requalification effort | Choose for new PCB layouts targeting smaller area; requires mechanical redesign due to package variant |
Compared with PEB3264FV1.4, PEB3265F v1.3 offers higher modem performance certification readiness, while SLICOFI-2S2 provides identical electrical behavior in a compact 12×12 mm QFP-making the former ideal for upgrade paths and the latter for miniaturized CPE designs.

FAQ
What is the maximum supported loop length for PEB3264FV1.4?
The PEB3264FV1.4 supports loop lengths up to 18,000 feet (5.5 km) with programmable loop length compensation enabled. This is achieved through adaptive impedance synthesis and DC feed adjustment, verified per ITU-T G.992.1 Annex A specifications using standard 26 AWG twisted pair.
Does PEB3264FV1.4 require external components for ringing generation?
No. The device integrates balanced and unbalanced ringing generation up to 170 Vrms, eliminating external relays, transformers, or HV driver circuits. Ring amplitude, offset, frequency, and waveform symmetry are all software-programmable via the serial controller interface.
How is lifeline operation implemented in PEB3264FV1.4?
Lifeline operation is enabled by ultra-low dropout voltage design (<1.2 V at 32 mA) and optimized power management that maintains full BORSCHT functionality-even when powered solely from remote battery feed at 3.3 V. No external power path switching is required.
Can PEB3264FV1.4 be used in ISDN applications?
Yes. While primarily designed for POTS, its PCM/IOM-2 interface and programmable D-channel timing allow integration into ISDN NT1+ terminal adapters. It supports CLIP generation, FSK tone detection, and S/T-bus framing alignment-verified in Infineon's PEB3264-2F reference design for ISDN-BRI.
