Product details
Overview
PEB4264-2TV1.1 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 per channel, supports balanced/unbalanced ringing up to 170 Vrms, integrates line testing, DTMF detection, and echo cancellation with ≤8 ms tail length.
For engineers reviewing the PEB4264-2TV1.1 datasheet, PEB4264-2TV1.1 pinout, PEB4264-2TV1.1 application, or PEB4264-2TV1.1 equivalent, this device serves as a programmable, low-power SLIC solution requiring precise longitudinal balance, lifeline support, and integrated diagnostics for voice-over-packet infrastructure.
Technical Context
The PEB4264-2TV1.1 implements a fully programmable dual-channel SLIC architecture with independent control of DC feed, ring trip, loop length, and AC impedance. It supports both 3.3 V and 5.0 V supply rails and enables lifeline operation via ultra-low quiescent power consumption.
Its integrated line testing measures short-circuit, foreign voltage, capacitance, and resistance without external instrumentation. The device interfaces via serial controller and PCM/IOM buses, and embeds DTMF receiver, CLIP generator, metering pulse (TTX), and tone generation functions.

FAQ
What is the maximum supported loop length for PEB4264-2TV1.1?
The device supports up to 5 km of 26 AWG twisted-pair copper loop under standard 32 mA DC feed and 170 Vrms ringing conditions, verified per ITU-T G.991.2 and GR-909 specifications. Loop length is programmable via serial interface to adapt to local line characteristics and regulatory limits.
Does PEB4264-2TV1.1 require external components for DTMF decoding?
No. The device integrates a full DTMF receiver compliant with ITU-T Q.23 and Q.24, capable of detecting all 16 standard tones without external filters or decoders. Tone generation and CLIP transmission are also handled internally using programmable FSK/DTMF engines.
How does lifeline mode operate during AC power failure?
In lifeline mode, the device automatically switches to low-power state drawing <50 mW per channel from the –48 V telecom supply, maintaining DC feed and basic supervision on at least one line. Ringing and advanced features are disabled, but emergency call origination remains functional per FCC Part 68 and EN 301 489-1.
Can PEB4264-2TV1.1 be used in ISDN NT1 applications?
Yes. Its programmable longitudinal balance (53 dB), integrated CLIP generation, metering pulse (TTX) output, and balanced ringing meet ETSI TS 101 515 and ANSI T1.601 for ISDN NT1+ implementations. Serial configuration allows region-specific parameter tuning without hardware change.
