Product details
Overview
PEB4265-2TV1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable POTS line interface applications in CPE equipment. It integrates balanced/unbalanced ringing generation, 32 mA DC feed capability, up to 170 Vrms ringing voltage, and supports lifeline operation with 3.3 V supply. Used in residential gateways and IP phones requiring full analog telephony functionality.
For engineers reviewing the PEB4265-2TV1.1 datasheet, PEB4265-2TV1.1 pinout, PEB4265-2TV1.1 application, or PEB4265-2TV1.1 equivalent, key selection criteria include programmable ring voltage/offset, integrated line testing, DTMF detection, echo cancellation support, and compatibility with SLICOFI-2 codec-filter in DuSLIC chipset architecture.
Technical Context
The PEB4265-2TV1.1 implements a fully programmable dual-channel SLIC with integrated high-voltage power switches and current-sense feedback. It operates with ±5 V or 3.3 V supply rails and delivers up to 32 mA per channel for loop feeding while maintaining <2.5 Vrms AC impedance matching per ITU-T G.992.3.
It interfaces via serial control bus to companion devices like SLICOFI-2 and supports remote line diagnostics including short-circuit, foreign voltage, capacitance, and resistance measurement - enabling QoS assurance without on-site service visits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual-channel SLIC supporting two independent POTS lines with shared control interface. |
| DC Feed Current | 32 mA per channel - meets lifeline requirement for emergency call support under remote battery feed. |
| Ringing Voltage | 170 Vrms balanced - sufficient for global POTS ring signal compliance including North America and EU standards. |
| Supply Voltage | 3.3 V single-supply operation - enables full-system 3.3 V design without level-shifting or auxiliary rails. |
| Longitudinal Balance | 53 dB - ensures adequate common-mode rejection for noise immunity in noisy CPE environments. |
| Line Testing | Integrated short-circuit, foreign voltage, capacitance, resistance measurement - eliminates need for external test circuitry. |
Pinout & Package
PEB4265-2TV1.1 is housed in a P-VQFN-48 package (15.9 × 14.2 mm, 0.5 mm pitch), thermally enhanced for high-voltage analog operation in compact CPE designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | 3.3 V main power rail for logic and driver stages; decoupling required per high-frequency switching. |
| GND | Ground reference | Analog/digital common return; separate AGND/DGND routing recommended for noise isolation. |
| LINE1+, LINE1− | Differential POTS line interface Channel 1 | High-voltage differential pair connected directly to telephone line; supports ±170 V transient tolerance. |
| LINE2+, LINE2− | Differential POTS line interface Channel 2 | Independent second line interface with identical voltage/current specs and protection as Channel 1. |
| SCLK, SDATA, SCEN | Serial control interface | 3-wire SPI-compatible bus for programming ring parameters, feed current, test modes, and status readback. |
| ALERT | Interrupt output | Open-drain signal indicating fault conditions (overcurrent, overtemperature, line fault detection). |
Key Features
| Feature | Design Value |
|---|---|
| Programmable ring voltage & offset | Enables single hardware platform to meet regional ring specifications (e.g., 90 Vrms EU vs. 170 Vrms NA) without BOM change. |
| Integrated line testing | Reduces field service costs by enabling remote diagnostics of line faults - no technician dispatch required for basic troubleshooting. |
| Lifeline power management | Guarantees at least one active line during AC power loss using remote battery feed, satisfying emergency calling mandates. |
| 3.3 V operation | Eliminates need for 5 V or ±12 V supplies in modern low-power CPE, simplifying power architecture and reducing component count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4265-2V v1.1 | Same dual-channel TSLIC but uses unbalanced ringing only (no balanced mode support); lower longitudinal balance (53 dB vs. 53 dB same). | Targeted at cost-sensitive CPE where balanced ringing is not required (e.g., non-North American markets). | Select when regional ring standard permits unbalanced topology and board space allows larger external components for balancing. |
| PEB4365T v1.1 | Dual-channel TSLIC with higher 50 mA feed current and 90 Vrms unbalanced ringing; different package (P-DSO-36-10). | Designed for linecard applications requiring higher loop current and thermal robustness in central office environments. | Choose for carrier-grade deployments needing extended loop reach (>10 km) or higher reliability under continuous load. |
Compared with PEB4265-2V v1.1, the -2TV1.1 adds balanced ringing support critical for North American POTS compliance; versus PEB4365T v1.1, it trades feed current headroom for smaller VQFN footprint and lifeline-optimized 3.3 V operation in CPE.
