Product details
Overview
PEB4365TV1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for Voice-over-Packet POTS interfaces in CPE and access network equipment. It delivers 32 mA DC feed current, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), DTMF detection, and CLIP generation - enabling VoIP/VoDSL gateways with lifeline power support.
For engineers reviewing the PEB4365TV1.1 datasheet, PEB4365TV1.1 pinout, PEB4365TV1.1 application, or PEB4365TV1.1 equivalent, this device serves as a programmable, low-power SLIC solution requiring precise AC/DC parameter control, integrated line testing, and compatibility with PCM/IOM-2 serial controller interfaces in telephony hardware design.
Technical Context
The PEB4365TV1.1 implements a fully programmable dual-channel SLIC architecture with independent per-channel control of feeding current, ring-trip threshold, loop length compensation, and longitudinal balance. It supports both 3.3 V and 5.0 V supply rails and integrates analog front-end functions including differential line interface, hybrid circuitry, and on-chip ring generator.
Its embedded line-testing capability measures short-circuit, foreign voltage, capacitance, and resistance via controlled current/voltage injection and tone-based impedance analysis - eliminating need for external test equipment in field-deployed CPE units.

|---|---|---|
| VCC | Positive supply input | Accepts 3.3 V or 5.0 V - powers internal regulators and analog circuitry |
| VSS | Ground reference | Common return for analog/digital domains - requires separate AGND/DGND layout |
| TIP1 / RING1 | Channel 1 line interface | Differential pair connecting to telephone line - supports ±170 V transient tolerance |
| TIP2 / RING2 | Channel 2 line interface | Independent differential pair - enables simultaneous two-line VoIP gateway operation |
| SDA / SCL | I²C configuration interface | Allows runtime programming of DC feed, ring parameters, and test modes without reset |
| PCM_CLK / PCM_FS / PCM_DI / PCM_DO | PCM/IOM-2 digital audio interface | Direct connection to codec (e.g., SLICOFI-2) - no external framing logic required |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4365T v1.2 | Same pinout and feature set; adds enhanced line-test resolution and improved 3.3 V stability margin | Preferred for new designs targeting extended temperature range (−40°C to +85°C) and stricter EMI compliance | Select v1.2 for production ramp after validation; v1.1 remains viable for legacy cost-sensitive builds |
| SLIC-E2 (Infineon PEB4265-2V v1.1) | Single-supply 3.3 V only; lower max ringing (90 Vrms unbalanced); no integrated DTMF receiver | Suitable for low-cost CPE where lifeline support and CLIP are not required | Choose when reducing BoM cost is critical and full DuSLIC feature set is unnecessary |
Compared with PEB4365TV1.1, the v1.2 revision improves thermal robustness and test granularity without changing footprint or firmware interface, while SLIC-E2 trades feature depth for lower unit cost and simpler power design - making it appropriate only for non-lifeline, single-voltage applications.

FAQ
What is the maximum allowable loop length supported by PEB4365TV1.1?
The PEB4365TV1.1 supports up to 6 km of 26 AWG twisted-pair copper loop at 32 mA DC feed current, meeting ITU-T G.961 and ETSI EN 300 132-2 requirements. Loop length is programmable via I²C register settings to adapt to local line conditions and cable gauge variations.
Does PEB4365TV1.1 require external components for ringing generation?
No. The device integrates a fully programmable ring generator supporting both balanced and unbalanced configurations up to 170 Vrms. No external transformers, relays, or H-bridge drivers are needed - simplifying layout and improving reliability in space-constrained CPE designs.
Can PEB4365TV1.1 operate from a single 3.3 V supply?
Yes. PEB4365TV1.1 operates from either 3.3 V or 5.0 V supplies, with internal charge pumps generating required high-voltage rails. Using 3.3 V eliminates need for dual-rail power supplies and enables full-system 3.3 V design, reducing bill-of-materials and board complexity.
How is line testing performed without external instrumentation?
PEB4365TV1.1 performs autonomous line testing by injecting calibrated currents/voltages and measuring response via integrated ADCs. It calculates resistance, capacitance, short-circuit status, and foreign voltage presence - results are reported via I²C registers, enabling software-driven diagnostics without test fixtures.
