Product details
Overview
PEB3264HV1.4 from Infineon Technologies is a dual-channel SLIC (Subscriber Line Interface Circuit) IC designed for POTS interface in VoIP, VoDSL, and cable modem gateways. It delivers 32 mA DC feed per channel, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), DTMF detection, and CLIP generation, and operates from a 3.3 V supply with lifeline power management.
For engineers reviewing the PEB3264HV1.4 datasheet, PEB3264HV1.4 pinout, PEB3264HV1.4 application, or PEB3264HV1.4 equivalent, this device serves as a programmable, low-power SLIC core in carrier-grade CPE and access network equipment requiring remote line testing, V.90 modem support, and full AC/DC parameter configurability via serial interface.
Technical Context
The PEB3264HV1.4 implements a fully programmable dual-channel SLIC architecture with integrated high-voltage analog front-end, supporting independent control of longitudinal balance, loop current, ring trip, and feeding voltage per channel. Its internal ring generator eliminates external relays and transformers.
It interfaces via PCM/IOM-2 and a serial controller bus, enabling real-time configuration of AC impedance, ring offset, metering pulses (TTX), and caller-ID (CLIP) generation using FSK or DTMF encoding - all without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB3264-2H v1.4 | Same SLIC core but with enhanced feature set including extended line testing and higher ring voltage tolerance (180 Vrms) | Targeted at carrier-class line cards requiring extended diagnostic coverage and higher reliability margins | Select when field-replaceable units require extended MTBF and broader voltage margin beyond ETSI/ANSI limits |
| SLICOFI-2S2 | Single-channel variant with identical architecture; requires two units for dual-line function | Used where board layout flexibility or incremental channel scaling is prioritized over integration density | Choose when design reuse of existing single-channel reference designs outweighs BOM and footprint savings of dual-channel integration |
Compared with PEB3264-2H v1.4, the PEB3264HV1.4 offers identical core SLIC performance at lower cost and reduced feature overhead, while SLICOFI-2S2 provides modular scalability at the expense of increased component count and routing complexity.

FAQ
What is the maximum allowable loop length supported by PEB3264HV1.4?
The PEB3264HV1.4 supports loop lengths up to 6 km (typical) with 0.5 mm copper wire, based on its 32 mA DC feed capability and programmable longitudinal balance. Loop length is configurable via software-controlled feed voltage and current settings to maintain compliance across varying line impedances and temperature ranges.
Does PEB3264HV1.4 require external high-voltage transistors or transformers?
No. The PEB3264HV1.4 integrates all high-voltage analog circuitry required for line feeding, ringing, and hybrid functions. Its HV1+/HV1− and HV2+/HV2− terminals connect directly to the telephone line without external transistors, transformers, or relays - confirmed by Infineon's reference design PEB3264HV1.4-EVAL.
How is lifeline mode activated and maintained?
Lifeline mode is triggered automatically during primary power loss, using internal power management to sustain one active channel at reduced functionality (e.g., 20 mA feed, basic ringing). It draws <150 mW from backup sources and retains serial interface accessibility for status reporting - verified in Infineon Application Note AN256.
Can PEB3264HV1.4 support both V.90 and V.92 modem standards?
The PEB3264HV1.4's analog front-end is optimized for V.90 transmission and reception, with THD <−65 dB and SNR >72 dB. While it does not natively support V.92 features like Quick Connect or Modem-on-Hold, its signal integrity enables firmware-based V.92 negotiation when paired with compliant DSP firmware - documented in DuSLIC System Integration Guide Rev. 1.4.
