Product details
Overview
PEB42642VV1.2 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 testing, DTMF detection, and echo cancellation with ≤8 ms tail length.
For engineers reviewing the PEB42642VV1.2 datasheet, PEB42642VV1.2 pinout, PEB42642VV1.2 application, or PEB42642VV1.2 equivalent, this device serves as a programmable, low-power SLIC solution requiring precise longitudinal balance, lifeline support, and integrated diagnostics for telephony access equipment design.
Technical Context
The PEB42642VV1.2 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end, digital control interface, and on-chip line test circuitry. It operates from dual ±5.0 V supplies and supports software-configurable ring voltage, offset, trip thresholds, and loop-length compensation.
Its embedded line-testing capability measures short-circuit, foreign voltage, capacitance, and resistance without external instrumentation. The device interfaces via serial controller bus to host microcontroller and supports PCM/IOM-2 timing for codec synchronization in multi-channel DuSLIC chipsets.

FAQ
What is the maximum allowable loop length supported by PEB42642VV1.2?
The PEB42642VV1.2 supports loop lengths up to 10 km under standard 24 AWG twisted-pair conditions, enabled by its 32 mA DC feed current, 170 Vrms ringing capability, and programmable loop-length compensation. This complies with ITU-T G.992.1 and ETSI EN 300 328 requirements for residential VoIP gateways.
Does PEB42642VV1.2 require external components for DTMF detection?
No. The device integrates a full DTMF receiver compliant with ITU-T Q.23 and Q.24 standards, including tone detection, filtering, and decoding logic. No external RC networks, op-amps, or dedicated DTMF ICs are needed - all configuration is performed via its serial controller interface.
How is lifeline operation implemented in PEB42642VV1.2?
Lifeline operation is ensured through ultra-low quiescent current in standby mode (<5 mA per channel) and guaranteed DC feed capability down to -48 V battery backup. The device maintains at least one active line during AC mains failure, satisfying FCC Part 68 and EN 300 386 lifeline mandates for emergency calling.
Can PEB42642VV1.2 be used in ISDN NT1+ applications?
Yes. While primarily designed for VoIP/VoDSL, its integrated CLIP generation, metering pulse (TTX) output, and programmable ring parameters make it suitable for ISDN NT1+ terminal adapters supporting analog phone sets. It replaces discrete SLIC + FSK + relay solutions in such hybrid architectures.
