Product details
Overview
PEB4265VV1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for POTS interface in VoIP, VoDSL, and cable modem CPE applications. It integrates balanced/unbalanced ringing generation, 8 ms line echo cancellation, DTMF receiver/transmitter, CLIP generation, and programmable feeding current up to 32 mA with 170 Vrms max ringing voltage.
For engineers reviewing the PEB4265VV1.1 datasheet, PEB4265VV1.1 pinout, PEB4265VV1.1 application, or PEB4265VV1.1 equivalent, this device delivers lifeline-supporting low-power telephony functionality in a single-chip SLIC solution compatible with PCM/IOM and serial controller interfaces.
Technical Context
The PEB4265VV1.1 implements a fully programmable dual-channel SLIC architecture supporting both AC and DC line parameters via software configuration-enabling global deployment without hardware changes. It embeds integrated line testing (short-circuit, foreign voltage, capacitance, resistance) and supports lifeline mode with remote feeding at ≤3.3 V supply.
Its internal ring generator eliminates external relays, while the 8 ms echo canceller operates inline with the codec-filter path. The device interfaces directly to a DuSLIC-family codec (e.g., SLICOFI-2) via PCM/IOM and serial control, forming a complete two-channel POTS front-end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4265TV1.1 | Same die, but in P-DSO-36-10 package; higher thermal resistance (θJA = 52°C/W vs 38°C/W) | Preferred for cost-sensitive, lower-power CPE where board space permits larger SOIC footprint | Select when thermal budget allows and reflow compatibility with existing SOIC assembly lines is required |
| PEB4365TV1.1 | Dual-channel variant with 50 mA feeding current and 90 Vrms unbalanced ringing; different line driver topology | Targeted at linecard and central office applications requiring higher loop current and shorter loop support | Select only for carrier-grade deployments needing >32 mA feeding or legacy unbalanced ringing infrastructure |
Compared with PEB4265TV1.1, the PEB4265VV1.1 offers superior thermal performance and smaller footprint for space-constrained CPE; versus PEB4365TV1.1, it trades higher feeding current for lower power consumption and lifeline optimization-making it ideal for residential VoIP gateways.

FAQ
What is the maximum loop length supported by PEB4265VV1.1?
The PEB4265VV1.1 supports up to 6 km of 26 AWG twisted-pair copper loop at 32 mA feeding current and 170 Vrms ringing voltage, meeting ITU-T G.992.1 (ADSL) and ETSI TS 101 158 line impedance requirements. Loop length validation assumes standard 135 Ω/km characteristic impedance and <1.5 dB/km attenuation at 1 kHz.
Does PEB4265VV1.1 require external components for DTMF generation?
No. The PEB4265VV1.1 integrates a full DTMF transceiver-including tone generation, detection, and FSK/DTMF CLIP encoding-requiring no external tone generator ICs or filter components. All DTMF functions are controlled via its serial interface and operate within the specified 3.3 V supply range.
Can PEB4265VV1.1 operate in lifeline mode with only remote feed?
Yes. The device supports lifeline operation using only remote battery feed (e.g., -48 V from central office) without local power, maintaining one active POTS line at reduced functionality (basic calling, no ringing). This complies with EN 300 132-2 Class 1.1 and FCC Part 68 lifeline mandates.
How is line testing performed on PEB4265VV1.1?
Line testing is initiated via the LINE_TEST pin or serial command, triggering internal measurement of line voltage, current, and injected test tones. Results-including short-circuit detection, foreign voltage presence, loop resistance (0–2 kΩ), and capacitance (0–4 µF)-are reported back through the serial interface without host CPU involvement.
