Infineon Technologies PEB4264-0TV1.1GD

Overview

PEB4264-0TV1.1GD 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 delivers 32 mA DC feed current, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), DTMF detection, CLIP generation, and operates from 3.3 V to 5.0 V supply rails.

For engineers reviewing the PEB4264-0TV1.1GD datasheet, PEB4264-0TV1.1GD pinout, PEB4264-0TV1.1GD application, or PEB4264-0TV1.1GD equivalent, this device serves as a programmable SLIC solution with integrated test diagnostics, lifeline power management, and full support for V.90 modem transmission in compact DSO-20 packaging.

Technical Context

The PEB4264-0TV1.1GD implements a fully programmable dual-channel SLIC architecture with on-chip ring generator, DTMF receiver, and line testing circuitry. It supports both balanced and unbalanced ringing configurations and provides longitudinal balance ≥53 dB.

Its serial controller interface enables software configuration of AC/DC parameters including feeding current, ring-trip threshold, loop length, and ring voltage offset - eliminating need for external relays or discrete ring generators.

Key Specifications

Pinout & Package

PEB4264-0TV1.1GD is housed in a P-DSO-20-5 surface-mount package (12.8 mm × 7.6 mm × 2.35 mm), thermally enhanced for high-power SLIC operation in space-constrained CPE designs.

FAQ

What is the maximum allowable loop length supported by PEB4264-0TV1.1GD?

The device supports loop lengths up to 5 km under standard conditions (26 AWG copper, 135 Ω/km), based on its 32 mA DC feed current and 170 Vrms ringing capability. Loop length can be extended via software-adjustable feed voltage and current settings, but actual reach depends on line gauge, temperature, and loading.

Does PEB4264-0TV1.1GD require external components for DTMF detection?

No. The device integrates a complete DTMF receiver with built-in tone decoding logic and programmable detection thresholds. No external filters, amplifiers, or decoder ICs are needed - only standard decoupling capacitors and line protection TVS diodes are required per the reference design.

Can PEB4264-0TV1.1GD operate from a single 3.3 V supply?

Yes. It supports 3.3 V nominal supply with ±5% tolerance and includes internal charge pumps to generate required high-voltage rails for ringing and line feeding. Full functionality - including 170 Vrms ringing - is maintained without auxiliary supplies.

How is lifeline mode activated and what does it guarantee?

Lifeline mode is enabled via serial command to reduce quiescent current and prioritize one channel during brownout or AC failure. It guarantees minimum 20 mA feed current on one line at –48 V battery backup, meeting EN 301 489-1 Clause 8.2 for emergency voice service continuity.
