Product details
Overview
PEB4265TV1.1GD from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable CPE applications. 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 POTS line emulation.
For engineers reviewing the PEB4265TV1.1GD datasheet, PEB4265TV1.1GD pinout, PEB4265TV1.1GD application, or PEB4265TV1.1GD equivalent, key selection criteria include programmable ring-trip threshold, longitudinal balance ≥53 dB, integrated line testing, and compatibility with SLICOFI-2 codec-filter in DuSLIC chipset architecture.
Technical Context
The PEB4265TV1.1GD implements a fully programmable dual-channel SLIC with independent control of DC feed current, ring voltage amplitude/offset, and loop supervision states. It supports both balanced and unbalanced ringing topologies without external relays or transformers.
It interfaces via serial controller interface to companion devices like SLICOFI-2, enabling coordinated DTMF detection, echo cancellation (up to 8 ms), and CLIP generation. Its 3.3 V operation enables single-supply system designs while maintaining lifeline compliance under remote feeding conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4265-2T v1.1 | Same silicon revision, identical electrical specs, but shipped in tape-and-reel only (no tray option). | No functional difference; suitable for automated SMT assembly only. | Select when high-volume pick-and-place is used and tray packaging is unnecessary. |
| PEB4365T v1.1 | Dual-channel variant with 50 mA DC feed and 90 Vrms unbalanced ringing - higher feed current, lower ringing voltage. | Better suited for shorter loops (<5 km) and linecard applications where higher current is prioritized over ringing amplitude. | Choose for metro CPE deployments requiring enhanced loop current headroom at reduced ringing voltage. |
Compared with PEB4265TV1.1GD, PEB4265-2T v1.1 offers identical performance in automated manufacturing environments, while PEB4365T v1.1 trades ringing voltage for higher feed current - making it preferable for dense urban deployments with short loops and strict thermal constraints.

FAQ
What is the maximum allowable loop length supported by PEB4265TV1.1GD?
The device supports loop lengths up to 10 km using 26 AWG copper wire, based on its 32 mA DC feed current and 170 Vrms ringing capability. This is verified per ITU-T G.991.2 and GR-909 specifications for lifeline operation under worst-case impedance conditions.
Does PEB4265TV1.1GD require external components for ringing generation?
No external relays, transformers, or H-bridge drivers are required. The device integrates fully differential Class-D ringing amplifiers capable of delivering balanced 170 Vrms or unbalanced 90 Vrms directly to the line pair.
How is line testing performed on PEB4265TV1.1GD?
Line testing is executed via serial command - the device measures line voltage, current, and injected test tones to detect shorts, opens, foreign voltage, capacitance, and loop resistance. Results are reported through the ALERT pin and serial interface registers.
Can PEB4265TV1.1GD operate from a single 3.3 V supply in lifeline mode?
Yes - the device maintains full functionality including 32 mA feed and ringing generation from a single 3.3 V rail, even during AC power loss. Its internal charge pumps and low-dropout regulators ensure lifeline compliance without auxiliary supplies.
