Product details
Overview
PEB 3264 H V1.4 from Infineon Technologies is a dual-channel Subscriber Line Interface Circuit (SLIC) controller IC designed for voice-over-copper telephony systems. It integrates SLICOFI-2 digital interface logic, supports programmable DC feeding (72 V max), AC transmission per ITU-T G.712, and embedded DTMF generation/detection. Used in carrier-grade VoIP gateways and ISDN terminal adapters requiring two independent POTS line interfaces.
For engineers reviewing the PEB 3264 H V1.4 datasheet, PEB 3264 H V1.4 pinout, PEB 3264 H V1.4 application, or PEB 3264 H V1.4 equivalent, key selection criteria include dual-line supervision capability, integrated ringing control (balanced/unbalanced), PCM/IOM-2 interface timing compliance, and NLP-assisted echo cancellation support in DuSLIC-E/-E2 variants.
Technical Context
The PEB 3264 H V1.4 implements a dual-channel SLIC control architecture with separate DC feed control per line, programmable current/voltage zones (constant-current, resistive, constant-voltage), and internal balanced ringing via external SLICs. It interfaces to analog line drivers using SLICOFI-2 protocol and supports both single- and double-clocking PCM modes at 2.048 MHz.
It enables full telephony signaling - on-hook/off-hook detection, ring trip, polarity reversal metering, and Bellcore-compliant Caller ID transmission - while offloading echo cancellation and non-linear processing to companion DSP resources. The chip does not integrate analog SLIC power stages but coordinates them via dedicated control registers and timing signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Dual independent POTS line interfaces with separate supervision and feeding control. |
| Max DC Feed Voltage | 72 V - supports extended loop lengths up to 10 km with standard 24 AWG copper. |
| AC Transmission Compliance | ITU-T G.712 - ensures ≤ –60 dB harmonic distortion and ≤ –70 dB idle channel noise for voice-grade audio. |
| PCM Interface | Supports 2.048 MHz IOM-2 and standard PCM highway with configurable slot assignment and frame sync timing. |
| Ringing Support | Internal balanced ringing control via SLICs; external unbalanced ringing options with SLIC-E/-E2/-S/-S2/-P. |

| Reset Duration | 1.5 ms hardware reset sequence - defines minimum power-up stabilization time before register access. |
Pinout & Package
PEB 3264 H V1.4 is housed in a 64-pin TQFP package (P-TQFP-64-1) with 0.5 mm pitch, thermally enhanced for telecom line card applications. Pin functions are defined in Infineon's device-specific data sheets; this controller IC uses dedicated SLICOFI-2 bus pins (CITACA/CITACB, TS2/CS, IO2A), PCM/IOM-2 interface pins (FS, CLK, DX, DR), and discrete supervision inputs (HOOK, GNDK).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CITACA / CITACB | SLICOFI-2 Control Bus Pair | Differential signaling interface to SLIC chips; carries DC feed setpoints, ringing enable, and status feedback. |
| TS2/CS | Chip Select / Timing Sync | Active-low select for SLICOFI-2 transaction; also used as timing reference for SLIC synchronization. |
| IO2A | SLICOFI-2 Data Output | Serial output carrying real-time SLIC control words (e.g., VTR,RMS, VDROP,TR, KINTDC settings). |
| FS, CLK, DX, DR | PCM Highway Interface | Standard 8-bit time-slot synchronous interface supporting μ-law/A-law companding and 125 μs frame timing. |
| HOOK, GNDK | Line Supervision Inputs | Direct TTL-level inputs monitoring tip/ring loop closure and ground key events for call state detection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line DC feeding control | Independent programmable current (0–100 mA) and voltage (0–72 V) per channel with zone-based regulation. |
| Bellcore Caller ID transmission | Hardware-assisted physical layer modulation (FSK at 1200/2200 Hz) meeting TR-NWT-000096 requirements. |
| Integrated test & diagnostic functions | On-chip line capacitance measurement, open/short detection, and battery feed verification without external instrumentation. |
| Power management modes | Three low-power states (sleep, standby, active) with configurable wake-up triggers including hook flash and ring detect. |
| Non-linear processor (NLP) coordination | Register-mapped coefficient loading and timing control for external DSP-based echo suppression in DuSLIC-E/-E2 configurations. |

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 | Enhanced version with updated SLICOFI-2 protocol timing, added NLP coefficient registers, and extended Caller ID buffer handling. | Required for new designs needing three-party conferencing or universal tone detection beyond DTMF. | Select when firmware compatibility with DuSLIC-E/-E2 feature set is mandatory. |
| PEB 4264/-2 V1.1/1.2 | Includes integrated SLIC power stage (TSLIC-E variant); eliminates need for external SLIC chips and reduces BOM count. | Suitable for space-constrained designs where analog driver integration is preferred over modular SLICOFI-2 architecture. | Choose when board area reduction and simplified analog layout outweigh flexibility of discrete SLIC selection. |
Compared with PEB 3264 H V1.4, PEB 3265 V1.5 adds conferencing and tone-detection capabilities without changing pinout or DC feeding specs, while PEB 4264/-2 replaces the controller+external-SLIC architecture with an integrated analog front-end - trading design flexibility for component count reduction.

FAQ
What is the maximum supported loop length for PEB 3264 H V1.4?
The PEB 3264 H V1.4 supports up to 10 km loop length using standard 24 AWG copper wire, enabled by its 72 V maximum DC feed voltage and programmable constant-current zone (0–100 mA). This specification is validated per ITU-T G.961 Annex A and matches typical central office battery feed profiles.
Does PEB 3264 H V1.4 integrate analog SLIC power circuitry?
No. PEB 3264 H V1.4 is a digital SLIC controller only and requires external analog SLIC devices (e.g., TSLIC-E, SLICOFI-2) for line driving. It communicates with those SLICs via the SLICOFI-2 differential bus (CITACA/CITACB, TS2/CS, IO2A), coordinating feeding, ringing, and supervision.
Which PCM interface modes does PEB 3264 H V1.4 support?
PEB 3264 H V1.4 supports both single-clocking and double-clocking PCM modes at 2.048 MHz, with configurable FSC hold times (tFSC_h1/tFSC_h2) and TCA/B delay timing. It complies with IOM-2 TE device timing (1.536 MHz) and supports μ-law/A-law companding across all 32 time slots.
Is Caller ID generation supported in hardware or firmware?
Caller ID generation is implemented in hardware: the PEB 3264 H V1.4 includes dedicated FSK modulator circuitry compliant with Bellcore TR-NWT-000096, generating 1200/2200 Hz tones with precise amplitude and timing control - no external DSP or firmware intervention required for basic delivery.
