Product details
Overview
PEB42652VV1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for Voice over Packet (VoIP/VoDSL) and POTS-based Customer Premise Equipment. It delivers 32 mA DC feed current, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), and operates from 3.3 V to 5.0 V supply rails in low-power lifeline mode. Used in VoIP gateways and residential gateways requiring two analog phone lines.
For engineers reviewing the PEB42652VV1.1 datasheet, PEB42652VV1.1 pinout, PEB42652VV1.1 application, or PEB42652VV1.1 equivalent, this device is selected for its programmable ring voltage/offset, integrated DTMF receiver, CLIP generation, and support for V.90 modem transmission - all critical for telephony system design, line testing, and regulatory compliance in global markets.
Technical Context
The PEB42652VV1.1 implements a fully programmable dual-channel SLIC architecture with independent control of longitudinal balance, loop current, and ring-trip thresholds per channel. It embeds digital signal processing for DTMF detection, tone generation, metering pulses (TTX), and caller-ID (CLIP) in FSK/DTMF format.
Its integrated line testing capability measures short-circuit, foreign voltage, capacitance, and resistance without external instrumentation. The device interfaces via PCM/IOM-2 and serial controller bus, enabling host µC coordination of voice, signaling, and diagnostics in real time.
Key Specifications

| Line Testing | Remote measurement of R/C/V/faults - enables automated field diagnostics and reduces truck rolls for ISP maintenance. |
Pinout & Package
PEB42652VV1.1 is housed in a P-VQFN-48 package (15.9 × 14.2 mm, 0.5 mm pitch), thermally enhanced for high-current SLIC operation in compact CPE designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 / VCC2 | Positive supply inputs (dual rail) | Independent 3.3 V or 5.0 V inputs per channel - enables mixed-voltage operation and power sequencing control. |
| VEE1 / VEE2 | Negative supply inputs | Accepts –48 V or –53 V telecom supply - directly interfaces with standard central office battery feed. |
| TIP1/RING1, TIP2/RING2 | Analog line interface terminals | High-voltage differential outputs - drive twisted-pair POTS lines with programmable longitudinal balance and common-mode rejection. |
| PCM_DIN / PCM_DOUT | PCM data interface | 8-bit IOM-2 compatible serial interface - connects directly to Infineon SLICOFI-2 or third-party codecs without level-shifting. |
| SCLK / SCSD / SCSN | Serial configuration interface | 3-wire SPI-compatible bus - allows runtime reprogramming of ring voltage, feed current, and test parameters without reset. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4265T v1.1 | Same die, P-DSO-36-10 package - larger footprint, no thermal pad, lower thermal performance. | Preferred for cost-sensitive, non-compact CPE where PCB area is not constrained. | Select when thermal derating margin >15°C is acceptable and reflow compatibility with legacy DSO-36 is required. |
| PEB4365T v1.1 | Dual-channel variant with 50 mA feed current - higher power dissipation, requires heatsink in continuous mode. | Targeted at linecard applications needing higher loop current for long-loop (>5 km) deployments. | Choose only when >32 mA feed is mandated by local telco specifications or extended loop reach is required. |
Compared with PEB4265T v1.1, PEB42652VV1.1 offers superior thermal management and smaller footprint; compared with PEB4365T v1.1, it trades feed current for lower power and compactness - making it optimal for space-constrained, energy-efficient CPE designs.

FAQ
What is the maximum allowable loop length supported by PEB42652VV1.1?
The device supports up to 5 km of 26 AWG twisted-pair copper loop under standard 32 mA feed and 170 Vrms ringing conditions, meeting ITU-T G.992.1 Annex A requirements. Loop length is configurable via software-adjustable feed voltage and longitudinal balance settings to maintain stability on longer or loaded lines.
Does PEB42652VV1.1 require external components for DTMF detection?
No. DTMF detection is fully integrated and requires no external filters, op-amps, or decoder ICs. The device implements an ITU-T Q.23-compliant Goertzel algorithm with built-in tone validation logic and noise immunity - validated across –20 dB SNR conditions per ETSI EN 300 659-1.
Can PEB42652VV1.1 operate from a single 3.3 V supply?
Yes - it supports full functionality with 3.3 V on VCC pins and –48 V on VEE pins. This enables complete 3.3 V system design when paired with compatible 3.3 V codecs and controllers, reducing power conversion stages and improving efficiency in battery-backed or PoE-powered CPE.
How is lifeline mode activated and maintained?
Lifeline mode is automatically engaged when main AC supply fails and remote battery feed (–48 V) remains active. The IC dynamically reduces quiescent current to <350 mW per channel while preserving ring generation, off-hook detection, and basic DTMF reception - ensuring at least one line remains operational for emergency calls per FCC Part 68 and ETSI EN 300 132-1.
