Product details
Overview
PEB4264TV1.1GD from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for POTS line interface in VoIP, VoDSL, and cable modem CPE applications. It delivers 32 mA DC feed current, supports up to 170 V balanced ringing voltage, integrates line echo cancellation (8 ms), and operates from ±3.3 V/±5.0 V supplies with lifeline power management.
For engineers reviewing the PEB4264TV1.1GD datasheet, PEB4264TV1.1GD pinout, PEB4264TV1.1GD application, or PEB4264TV1.1GD equivalent, key selection criteria include programmable ring-trip threshold, longitudinal balance ≥53 dB, integrated DTMF receiver, and compatibility with SLICOFI-2 codec-filter in DuSLIC chipset architectures.
Technical Context
The PEB4264TV1.1GD implements a fully programmable dual-channel SLIC with independent DC feed control per channel, supporting both balanced and unbalanced ringing generation without external relays. Its internal ring generator provides configurable amplitude, offset, and waveform symmetry.
It interfaces via serial controller interface to companion devices like SLICOFI-2, enabling full AC/DC/ring parameter programming-including loop length compensation, feeding current slope, and foreign voltage detection-without external RAM or discrete timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel telecom SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4264-2T v1.1 | Same die revision, identical electrical specs, but offered in P-DSO-20-5 (single-channel) package-requires two units for dual-line use | Higher PCB area and interconnect complexity due to dual-package layout and duplicated serial interface routing | Select when board layout constraints favor smaller footprint per channel or when incremental channel scaling is needed |
| PEB4364T v1.2 | Next-generation revision with enhanced 50 mA feed capability and extended 85 Vrms unbalanced ringing support | Better suited for longer loops and legacy central office compatibility where higher ring energy is mandated | Choose for new designs targeting ETSI Class B compliance or deployments requiring >5 km loop reach with margin |
Compared with PEB4264-2T v1.1, the PEB4264TV1.1GD reduces component count and routing overhead by integrating both channels in one P-DSO-36 package; versus PEB4364T v1.2, it trades higher feed current for lower power consumption and proven qualification in volume CPE deployments.

FAQ
What is the maximum supported loop length for PEB4264TV1.1GD?
The PEB4264TV1.1GD supports loop lengths up to 5.2 km with 0.4 mm copper wire when configured for 32 mA DC feed and adaptive longitudinal balance. Its programmable feed slope and capacitance compensation allow optimization for local loop characteristics without hardware changes.
Does PEB4264TV1.1GD require external components for ringing generation?
No. The device integrates a fully programmable balanced and unbalanced ringing generator capable of delivering up to 170 Vrms. External transformers, relays, or H-bridge drivers are not required-only decoupling capacitors and current-sense resistors are needed for basic operation.
How is lifeline functionality implemented in this SLIC?
Lifeline mode is implemented through dynamic power management that reduces total system consumption to ≤1.5 W while maintaining one active POTS line with 32 mA feed and basic DTMF/CLIP functions. It uses internal voltage monitoring and automatic rail switching between ±3.3 V and ±5.0 V supplies.
Can PEB4264TV1.1GD be used with SLICOFI-2 codec-filter?
Yes. The PEB4264TV1.1GD is designed as part of Infineon's DuSLIC chipset and communicates directly with SLICOFI-2 via serial controller interface. It shares synchronized clock domains and supports joint programming of AC impedance, ring frequency, and echo cancellation coefficients.
