Product details
Overview
PEB 3264 F V1.4 from Infineon Technologies is a dual-channel Subscriber Line Interface Circuit (SLIC) controller IC designed for integration with external SLIC analog front-ends in voice-over-copper telephony systems. It delivers programmable DC feeding (up to ±72 V), integrated ringing generation, DTMF detection/generation, caller ID support, and line echo cancellation - all synchronized to PCM or IOM-2 interfaces. Used in VoIP gateways, ISDN terminal adapters, and multi-line residential gateways.
For engineers reviewing the PEB 3264 F V1.4 datasheet, PEB 3264 F V1.4 pinout, PEB 3264 F V1.4 application, or PEB 3264 F V1.4 equivalent, this page provides verified functional context, confirmed DC/AC transmission specs, validated dual-channel supervision logic, and real-world deployment constraints for copper-line interface design.
Technical Context
The PEB 3264 F V1.4 implements a digital control core for two independent telephone lines, managing tip/ring DC bias, AC signal coupling, ring trip detection, and polarity reversal metering via configurable registers. Its architecture relies on external SLIC devices (e.g., PEB 4264/-2) for high-voltage analog conditioning while handling all digital signaling, timing, and protocol processing.
It supports both single- and double-clocking PCM modes (2.048 MHz frame sync), IOM-2 TE interface at 1.536 MHz, and includes dedicated hardware blocks for NLP (Non-Linear Processor), universal tone detection, and 16 kHz wideband audio path configuration - all operating under a unified register map with interrupt-driven status reporting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 3265 V1.5 | Added SLICOFI-2S support, updated NLP coefficient tables, and extended IOM-2 timing margins. | Required for new designs targeting SLICOFI-2S companion chips or enhanced caller ID buffer handling. | Select PEB 3265 if deploying with SLICOFI-2S or requiring updated DTMF detection algorithms per DS3 revision. |
| PEB 4264/-2 V1.2 | Analog SLIC front-end (not controller); requires pairing with PEB 3264 for full functionality. | Not a drop-in replacement - serves complementary role as high-voltage analog interface only. | Use PEB 4264/-2 as the mandatory analog companion; PEB 3264 remains essential for digital control. |
Compared with PEB 3265 V1.5, PEB 3264 F V1.4 lacks SLICOFI-2S register extensions and updated NLP coefficients, but offers identical core SLIC control, ringing, and PCM timing - making it suitable for legacy-compatible deployments where firmware stability is prioritized over feature expansion.

FAQ
What is the maximum supported loop length for PEB 3264 F V1.4?
The PEB 3264 F V1.4 itself does not drive loop current directly; it controls external SLICs such as PEB 4264/-2, which support up to 18 kΩ loop resistance. With ±72 V DC feeding and proper SLIC selection, this enables loop lengths exceeding 10 km on 0.4 mm copper wire per ITU-T G.960 specifications.
Does PEB 3264 F V1.4 include an integrated ADC/DAC?
No - PEB 3264 F V1.4 is a digital controller only. It interfaces with external codecs or SLICOFI companion chips (e.g., PEB 4264/-2 + PEB 4364) for analog-to-digital and digital-to-analog conversion. PCM data I/O (DTX/DRX) is handled at 8- or 16-bit resolution with μ-law/A-law companding.
Can PEB 3264 F V1.4 generate Bellcore-compliant ringing waveforms?
Yes - it supports internal balanced ringing via paired SLICs, delivering up to 90 V RMS at 20 Hz with programmable amplitude, duration, and cadence. The VTR,RMS and VTR0,RMS registers enable precise compliance with TR-NWT-0000009 Section 4.3.2.2 for Class A/B ringer loads.
Is there hardware support for echo cancellation in PEB 3264 F V1.4?
Yes - the DuSLIC-E variant family (including PEB 3264 F V1.4) integrates a dedicated Non-Linear Processor (NLP) block with on-chip CRAM for coefficient storage. This enables real-time hybrid echo suppression without offloading to host DSP, meeting ITU-T G.168 requirements for 48 dB return loss.
