Product details
Overview
PEB4265V V1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable customer premise equipment. It integrates balanced/unbalanced ringing generation, 32 mA DC feed capability, up to 85 Vrms ringing voltage, and supports PCM/IOM-2 interface with 3.3 V SLIC operation.
For engineers reviewing the PEB4265V V1.1 datasheet, PEB4265V V1.1 pinout, PEB4265V V1.1 application, or PEB4265V V1.1 equivalent, this device serves as a programmable, low-power line interface for voice-over-packet systems requiring lifeline support, integrated DTMF detection, and remote line testing without external relays or ring generators.
Technical Context
The PEB4265V V1.1 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end filtering, digital control via serial interface, and on-chip line testing circuitry for resistance, capacitance, and foreign voltage detection. It operates with 3.3 V supply for both SLIC and logic domains, enabling single-rail system design.
Its embedded echo cancellation supports up to 8 ms tail length, and it delivers V.90 modem transmission performance while maintaining compliance with global AC impedance, ring-trip, and longitudinal balance requirements through software-configurable parameters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4265T V1.1 | Same die, P-DSO-36-10 package - larger footprint, no exposed thermal pad | Preferred for through-hole assembly or where QFN reflow is not available | Select when thermal management is less critical and board assembly process favors SOIC-style packages |
| PEB4264V V1.2 | Single-channel variant in same P-VQFN-48 package - half the line capacity, identical feature set | Suitable for single-line CPE or space-constrained designs requiring only one POTS port | Choose when system requires only one analog line and PCB area must be minimized per channel |
Compared with PEB4265T V1.1, the PEB4265V V1.1 offers superior thermal performance via its exposed-pad QFN, while PEB4264V V1.2 trades channel count for density-making the V1.1 version optimal for dual-line, thermally demanding VoIP gateways.

FAQ
What is the maximum allowable loop length supported by PEB4265V V1.1?
The PEB4265V V1.1 supports loop lengths up to 5 km (typical) with 0.5 mm copper wire, based on its 32 mA DC feed current and programmable longitudinal balance of ≥53 dB. Loop length is adjustable via software-controlled feed voltage and impedance settings to meet regional regulatory limits.
Does PEB4265V V1.1 require external components for ringing generation?
No. The device integrates fully programmable balanced and unbalanced ringing generation, eliminating external transformers, relays, or H-bridge drivers. Ring amplitude, frequency, and cadence are configured via its serial interface, with output directly to LINE1/LINE2 terminals.
Can PEB4265V V1.1 operate with a 5 V supply?
No. The PEB4265V V1.1 is specified exclusively for 3.3 V operation on both VCC_SLIC and VCC_DIG rails. Using 5 V will damage the device. It is designed for single-rail 3.3 V systems, aligning with Infineon's DuSLIC chipset architecture.
How is line testing performed without external test equipment?
Internal test circuitry applies calibrated test tones and measures resulting voltage/current responses to calculate loop resistance, capacitance, and detect foreign voltage. Results are accessible via the serial interface register map, enabling automated diagnostics without external hardware.
