Product details
Overview
PEB4364TV1.2 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable POTS line interface applications in CPE and access network equipment. It delivers 32 mA DC feed current, supports up to 170 V balanced ringing voltage, operates from 3.3 V/5.0 V supplies, integrates line testing, and enables lifeline power mode.
For engineers reviewing the PEB4364TV1.2 datasheet, PEB4364TV1.2 pinout, PEB4364TV1.2 application, or PEB4364TV1.2 equivalent, this device serves as a programmable, low-power SLIC with integrated echo cancellation, DTMF detection, CLIP generation, and remote line diagnostics - critical for voice gateway, IP-PBX, and cable modem telephony designs.
Technical Context
The PEB4364TV1.2 implements a fully programmable dual-channel SLIC architecture with independent control of longitudinal balance, ring-trip threshold, loop length compensation, and AC impedance. It supports both balanced and unbalanced ringing configurations and embeds real-time line testing for short-circuit, foreign voltage, capacitance, and resistance measurement.
It interfaces via serial controller and PCM/IOM buses, enabling integration with Infineon's DuSLIC codec-filter family (e.g., SLICOFI-2). Its 3.3 V SLIC core allows full 3.3 V system design while maintaining lifeline operation through dynamic power management and low-drop voltage regulation.

FAQ
What is the maximum loop length supported by PEB4364TV1.2?
The PEB4364TV1.2 supports up to 6 km of 0.4 mm copper loop with 32 mA DC feed current and programmable longitudinal balance. Loop length compensation is adjustable via I²C to maintain signal integrity across varying line impedances and temperature conditions - verified per ITU-T G.992.1 and ETSI EN 300 132-2 standards.
Does PEB4364TV1.2 require external components for DTMF detection?
No. The PEB4364TV1.2 integrates a full DTMF receiver compliant with ITU-T Q.23 and Q.24, including tone detection, filtering, and decoding logic. No external RC networks, op-amps, or dedicated DTMF ICs are needed - all parameters (frequency tolerance, guard time, duration thresholds) are software-configurable via I²C.
Can PEB4364TV1.2 operate in lifeline mode with only 3.3 V supply?
Yes. The device supports full lifeline functionality - including sustained 32 mA feed on one channel - using only the 3.3 V rail. Its internal charge pump and low-drop regulator maintain required –48 V line bias even during AC mains failure, meeting GR-909 Section 4.3.2 lifeline continuity requirements.
How is line testing performed without external test equipment?
PEB4364TV1.2 performs autonomous line testing by injecting calibrated test tones and measuring resulting currents/voltages at TIP/RING terminals. It calculates loop resistance, capacitance, foreign DC voltage, and short-circuit status internally - results are reported via I²C registers, enabling host MCU to trigger alarms or log faults without external instrumentation.
