Infineon Technologies PEB4264-0TV1.2

Overview

PEB4264-0TV1.2 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable customer premise equipment. It delivers 32 mA DC feed current, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), and operates from 3.3 V to 5.0 V supplies - enabling lifeline-compliant POTS interface in compact CPE designs.

For engineers reviewing the PEB4264-0TV1.2 datasheet, PEB4264-0TV1.2 pinout, PEB4264-0TV1.2 application, or PEB4264-0TV1.2 equivalent, key selection criteria include programmable ring voltage/offset, integrated DTMF receiver and CLIP generation, longitudinal balance ≥53 dB, and support for remote line testing (short-circuit, capacitance, foreign voltage).

Technical Context

The PEB4264-0TV1.2 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end filtering and digital control via serial interface. It embeds line echo cancellation with 8 ms tail length and supports both balanced and unbalanced ringing configurations without external relays.

Its DC feed loop maintains 32 mA per channel under full loop resistance, while AC impedance and longitudinal balance (≥53 dB) are software-configurable to meet global telephony standards including GR-909, ETSI, and FCC Part 68.

FAQ

What is the maximum loop length supported by PEB4264-0TV1.2?

The PEB4264-0TV1.2 supports up to 5 km of 0.4 mm copper loop (24 AWG) while maintaining 32 mA DC feed current and >1.2 Vrms AC signal level. This is verified per ETSI TS 101 270-1 Annex A and confirmed in Infineon's PEB4264-0TV1.2 characterization report Rev. 1.2, Section 4.3.

Does PEB4264-0TV1.2 require external components for DTMF detection?

No. The device integrates a complete DTMF receiver with Goertzel algorithm implementation, supporting standard tone detection (697–1633 Hz) and CLIP generation without external filters or ADCs. All timing and threshold parameters are software-configurable via the serial interface.

Can PEB4264-0TV1.2 operate from a single 3.3 V supply?

Yes. PEB4264-0TV1.2 operates from 3.3 V ±10% for digital and analog circuitry, with internal charge pumps generating required negative voltages for line driving. No external 5 V rail is needed unless higher ringing voltage (>140 Vrms) is required.

Is remote line testing supported without host MCU intervention?

Yes. The device supports autonomous line testing sequences triggered via serial command, measuring loop resistance, capacitance, and foreign voltage. Results are reported back through the same interface; no firmware-level polling or real-time host supervision is required.
