Product details
Overview
PEB4264VV1.2 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 (8 ms), and operates from 3.3 V supply with lifeline power management.
For engineers reviewing the PEB4264VV1.2 datasheet, PEB4264VV1.2 pinout, PEB4264VV1.2 application, or PEB4264VV1.2 equivalent, this device is selected for low-power, programmable SLIC designs requiring integrated diagnostics, CLIP generation, and V.90 modem compatibility in compact dual-line telephony systems.
Technical Context
The PEB4264VV1.2 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end, digital control interface (serial controller), and on-chip line testing circuitry. It supports PCM/IOM-2 interface for codec coupling and enables software-configurable AC/DC parameters including ring voltage offset, longitudinal balance, and loop-length compensation.
Its design integrates echo cancellation with 8 ms tail length, DTMF receiver and tone generator, caller-ID (CLIP) generation, and metering pulse (TTX) output - all without external components. The device targets lifeline operation via dynamic power scaling between full-performance and low-drop modes under remote feeding constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual-channel SLIC supporting two independent POTS lines with shared control interface. |
| DC Feed Current | 32 mA per channel - sufficient for standard loop lengths up to 5 km with 1.3 mm copper. |
| Ringing Voltage | Up to 170 Vrms balanced or unbalanced - eliminates need for external relays or transformers. |
| Supply Voltage | 3.3 V single supply - enables full-system 3.3 V design, reducing BOM count and power conversion loss. |
| Line Testing | Integrated short-circuit, foreign-voltage, capacitance, and resistance measurement - enables remote QoS validation without field visits. |
| Echo Cancellation | 8 ms tail length - meets ITU-T G.168 requirements for packet-based voice networks (VoIP/VoATM). |
| DTMF Support | Integrated DTMF receiver and transmitter - provides touch-tone decoding/generation without external filters or ICs. |
Pinout & Package
PEB4264VV1.2 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 space-constrained CPE designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Primary power supply input | 3.3 V supply for internal logic and analog circuitry; decoupling required near pin. |
| GND | Analog/digital ground reference | Common return for SLIC outputs and digital interface; split grounding recommended for noise isolation. |
| TIP1 / RING1 | Channel 1 line interface terminals | Direct connection to telephone line pair; supports ±170 V transient tolerance with integrated protection. |
| TIP2 / RING2 | Channel 2 line interface terminals | Independent second POTS interface with identical voltage/current capability and protection as Channel 1. |
| SCLK / SDATA / SCEN | Serial controller interface | 3-wire SPI-compatible interface for real-time programming of ringing, feed, and diagnostic parameters. |
| PCM_IN / PCM_OUT | PCM data interface | Supports IOM-2 timing for synchronous 8-bit/16-bit PCM audio data exchange with external codec. |
| TEST_IN / TEST_OUT | Line test signal path | Enable injection and monitoring of test tones (e.g., 1 kHz, 2 kHz) for impedance/capacitance measurement. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Ring Generation | Software-selectable balanced/unbalanced mode, amplitude, frequency, and offset - eliminates external ring generators and relays. |
| Integrated Line Diagnostics | On-chip measurement of line resistance, capacitance, and foreign voltage - reduces factory test time and enables remote troubleshooting. |
| Lifeline Power Management | Automatic transition to low-drop mode (<2.5 V headroom) during remote feeding - ensures at least one line remains active in emergency power loss. |
| V.90 Modem Compatibility | Optimized analog front-end with >53 dB longitudinal balance - supports full-duplex V.90 modem transmission over POTS lines. |
| Caller-ID (CLIP) Generation | FSK/DTMF-based CLIP output synchronized to ring cadence - requires no external tone encoder or modulator. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4264-2V v1.2 | Same package and pinout; identical electrical specs but lacks integrated line testing circuitry. | Not suitable for remote diagnostics or QoS-certified deployments requiring automated line validation. | Select when cost sensitivity outweighs diagnostic capability and lifeline testing is handled externally. |
| PEB4364T v1.2 | Dual-channel TSLIC in P-DSO-36-10 package; supports higher 50 mA feed current and 90 V unbalanced ringing. | Better suited for linecard or central office applications where higher drive capability and thermal margin are required. | Select for carrier-grade access equipment needing extended loop reach or higher fault tolerance. |
Compared with PEB4264VV1.2, PEB4264-2V v1.2 trades integrated diagnostics for lower cost in static CPE deployments, while PEB4364T v1.2 offers greater drive strength and different packaging for infrastructure use - making PEB4264VV1.2 optimal for feature-rich, space-constrained residential gateways.

FAQ
What is the maximum supported loop length for PEB4264VV1.2 at full 32 mA feed current?
The PEB4264VV1.2 supports up to 5 km of 0.4 mm (26 AWG) copper loop at 32 mA DC feed current and 48 V battery voltage, meeting ETSI and FCC loop-length specifications for residential CPE. Performance is verified with 1.3 mm (16 AWG) cable up to 3 km under identical conditions.
Does PEB4264VV1.2 require external components for DTMF generation or detection?
No. The device integrates a complete DTMF receiver and transmitter with programmable tone frequencies, detection thresholds, and FSK/DTMF CLIP encoding - eliminating external filters, op-amps, or tone generators. Only passive RC network is needed for anti-aliasing on analog inputs.
Can PEB4264VV1.2 operate in lifeline mode with only remote battery feeding?
Yes. Its lifeline mode activates automatically when local 3.3 V supply drops below threshold, enabling operation from remote -48 V feed with <2.5 V headroom. It maintains one active channel with basic ringing and on-hook detection, satisfying EN 300 132-2 Class 1.1 emergency requirements.
Is the serial controller interface compatible with standard SPI protocols?
The SCLK/SDATA/SCEN interface follows SPI timing conventions but uses proprietary command framing and register mapping. It is not drop-in SPI-compatible; however, it operates at up to 10 MHz clock rate and supports full-duplex read/write with status polling - requiring Infineon's driver library or custom firmware implementation.
