Product details
Overview
PEB 3265 F V1.5 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 (72 V max), AC transmission compliant with ITU-T G.712, integrated DTMF generation/detection, caller ID buffer handling, and non-linear processor (NLP) support for echo suppression. Used in carrier-grade VoIP gateways and ISDN terminal adapters requiring dual-line supervision and ringing control.
For engineers reviewing the PEB 3265 F V1.5 datasheet, PEB 3265 F V1.5 pinout, PEB 3265 F V1.5 application, or PEB 3265 F V1.5 equivalent, key selection criteria include dual-line DC feed voltage range (±72 V), SLICOFI-2 interface timing, integrated NLP coefficient programming, and compatibility with DuSLIC-E/-E2/-P system architecture - all critical for PSTN line card design and legacy telephony migration.
Technical Context
The PEB 3265 F V1.5 implements a digital SLIC controller core that manages two independent TIP/RING lines via serial SLICOFI-2 interface, supporting both balanced and unbalanced ringing modes. It integrates a 16-bit PCM interface (single/double clocking), IOM-2 TE device support at 1.536 MHz, and hardware-assisted interrupt handling for hook, ground key, and ring trip events.
Its functional architecture includes dedicated registers for DC parameter programming (e.g., VTR,RMS, VTR0,RMS), AC path configuration (transmit/receive gain, matching), and enhanced signal processing blocks - including caller ID buffer management, universal tone detection, and three-party conferencing logic - all coordinated through a register-mapped memory space accessible via SPI-like serial command protocol (SOP/COP/POP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Dual independent line interfaces for simultaneous PSTN line supervision and signaling. |
| Max DC Feed Voltage | ±72 V - supports long-loop battery feeding per ITU-T G.961 and Bellcore TR-NWT-000332. |
| AC Transmission Compliance | ITU-T G.712 - ensures ≤ –60 dB harmonic distortion at 1 kHz, enabling carrier-grade voice quality. |
| PCM Interface | 16-bit, time-division multiplexed, supports single-clock (2.048 MHz) and double-clock (1.024 MHz) modes with programmable FSC hold times. |
| Caller ID Support | Integrated buffer handling for Bellcore/ETSI Phase I/II formats with LM-OK bit timing synchronized to 1 ms internal delay. |
| NLP Coefficient Storage | On-chip CRAM coefficients (including TTX slope nibbles 6–7) enable real-time non-linear echo cancellation without host CPU intervention. |
| Reset Duration | 1.5 ms hardware reset sequence - guarantees deterministic initialization of SLICOFI-2 interface and register defaults. |
Pinout & Package
PEB 3265 F V1.5 is housed in a 64-pin TQFP package (P-TQFP-64-1) with 0.5 mm pitch, thermally enhanced for line-card power dissipation. Pin assignments follow clockwise numbering per Infineon's security warning for SLIC packages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO / VDDA | Digital/Analog Power Supply | Separate 3.3 V domains isolate noise-sensitive analog SLICOFI-2 interface from digital logic. |
| CLK / FSC / DIO | PCM Timing Interface | Supports master/slave operation; FSC hold time 1 (tFSC_h1) and hold time 2 (tFSC_h2) enable precise frame sync alignment. |
| SOP / COP / POP | Serial Command Interface | Three-phase command bus (Start, Command, Parameter) for configuring SLICOFI-2 registers and loading NLP coefficients. |
| INT1 / INT2 | Interrupt Outputs | Active-low, open-drain signals flag hook state change, ground key detection, ring trip, and metering events. |
| TS2/CS | SLICOFI-2 Chip Select | Enables communication with external SLICOFI-2 devices; referenced in Figures 90, 92, and 94 for ringing circuit coordination. |
| CITACA / CITACB | Current Injection Test Access | Test pins for factory calibration of DC feed current zones (constant-current, resistive, constant-voltage) per Section 2.3. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable DC Feeding Zones | Configurable constant-current (up to 45 mA), resistive, and constant-voltage (±72 V) modes per line - enables compliance with regional loop-length requirements. |
| Integrated Caller ID Buffer | Dedicated RAM buffer with automatic LM-OK bit assertion after 1 ms - eliminates host polling overhead during ETSI/Bellcore message reception. |
| Hardware NLP Coefficient Loading | POP register sequence supports immediate programming of TTX slope coefficients (nibbles 6–7) - ensures zero-latency echo cancellation adaptation. |
| Dual-Ringing Method Support | Internal balanced (via SLICs) and external unbalanced (with SLIC-E/-E2 or SLIC-S/-S2) - provides flexibility for cost- vs. performance-optimized line card layouts. |
| IOM-2 TE Device Compatibility | Native 1.536 MHz interface support - simplifies integration with Infineon's IOM-2 transceivers in multi-port gateway designs. |

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 3264 V1.4 | Lower DC feed limit (50 V → 72 V in PEB 3265); no NLP coefficient extension (nibbles 6–7); missing LM-OK 1 ms timing. | Limited to medium-loop deployments; lacks caller ID buffer optimization for ETSI Phase II burst timing. | Select when legacy system compatibility outweighs long-loop reach and advanced echo cancellation. |
| PEB 4265/-2 V1.1/1.2 | Includes integrated SLIC analog front-end (not controller-only); different package (P-VQFN-48-4); higher power dissipation. | Reduces BOM count but sacrifices layout flexibility; requires thermal redesign for high-density line cards. | Select when board space is constrained and analog integration is preferred over modular SLICOFI-2 architecture. |
Compared with PEB 3264 V1.4, PEB 3265 F V1.5 adds 22 V DC feed headroom and NLP coefficient extensibility; versus PEB 4265/-2, it retains architectural modularity for optimized thermal management and SLIC vendor flexibility - critical for carrier-grade line card scalability.

FAQ
What is the maximum supported loop length for PEB 3265 F V1.5?
The PEB 3265 F V1.5 supports up to 72 V DC feed voltage per line, enabling operation on loops exceeding 6 km (3.7 miles) under ITU-T G.961 conditions. This is achieved through programmable constant-current (45 mA) and constant-voltage zones, validated in Section 2.3.5 of the DS3 preliminary datasheet. Loop length depends on local exchange battery voltage and cable gauge.
Does PEB 3265 F V1.5 integrate analog SLIC functionality or require external components?
PEB 3265 F V1.5 is a digital SLIC controller only and requires external analog SLIC devices (e.g., SLIC-E, SLIC-S, or SLIC-P) connected via the SLICOFI-2 interface. It does not contain on-die power transistors or line drivers. The "DuSLIC" architecture separates digital control (PEB 3265) from analog front-end (SLICOFI-2 + SLIC), as confirmed in Figure 32 and Section 2.2 of DS3.
How is caller ID data buffered and timed in PEB 3265 F V1.5?
Caller ID data is stored in an internal buffer managed by SLICOFI-2, with automatic LM-OK bit assertion occurring precisely 1 ms after valid data capture - a timing requirement added in DS3 revision for Version 1.5 (Page 99, Figure 44). This eliminates host-side timing uncertainty and enables deterministic buffer readout without polling overhead.
Can PEB 3265 F V1.5 support three-party conferencing without external DSP resources?
Yes - PEB 3265 F V1.5 implements hardware-assisted three-party conferencing logic within its EDSP block (Section 2.10), including mixing, gain control, and echo path management. It requires no external DSP for basic conferencing; however, full NLP and advanced echo cancellation depend on loaded CRAM coefficients (Pages 205, 258, 318).
