Product details
Overview
PEB4264TV1.2 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 testing, echo cancellation (8 ms), and DTMF detection - enabling full lifeline support in low-power 3.3 V systems.
For engineers reviewing the PEB4264TV1.2 datasheet, PEB4264TV1.2 pinout, PEB4264TV1.2 application, or PEB4264TV1.2 equivalent, this device serves as a programmable SLIC solution for VoIP gateways, residential gateways, and ISDN terminal adapters requiring integrated ring generation, remote line diagnostics, and V.90 modem compatibility.
Technical Context
The PEB4264TV1.2 implements a fully programmable dual-channel SLIC architecture with independent control of longitudinal balance, loop current, ring-trip threshold, and AC impedance. It interfaces via serial controller and PCM/IOM buses, supporting both standalone operation and integration with Infineon's DuSLIC codec-filter family (e.g., SLICOFI-2).
Its internal ring generator eliminates external relays and transformers, while integrated line testing measures short-circuit, foreign voltage, capacitance, and resistance - enabling QoS assurance without field service visits. Power management supports lifeline mode with minimum 3.3 V supply and <50 mW standby dissipation per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual-channel - enables two independent POTS lines on single IC, reducing BOM count in multi-line gateways. |
| DC Feed Current | 32 mA per channel - meets GR-909 lifeline requirements for emergency call support under remote battery feeding. |
| Ringing Voltage | 170 Vrms balanced / 90 Vrms unbalanced - satisfies global telephony standards (ETSI, FCC, ARIB) without external boost circuitry. |
| Supply Voltage | 3.3 V ±10% - allows full-system 3.3 V design, eliminating need for 5 V rails and associated regulators. |
| Line Testing | Integrated measurement of voltage, current, and tone response - enables automated remote diagnostics and reduces field maintenance cost. |
| Echo Cancellation | 8 ms tail length - suppresses hybrid echo in packet networks, ensuring voice clarity without external DSP resources. |
| DTMF Detection | Integrated receiver with programmable tone guardband - eliminates external DTMF decoder IC and simplifies firmware stack. |
Pinout & Package
PEB4264TV1.2 is housed in a P-DSO-36-10 thermally enhanced dual-row SOIC package (12.8 mm × 12.8 mm × 2.35 mm), optimized for high-voltage isolation and thermal dissipation in telecom line cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | 3.3 V main power rail; decoupling required within 5 mm for noise immunity in analog sections. |
| VEE | Negative supply input | −48 V or −53 V return path; connects to central telecom battery ground with low-inductance trace routing. |
| TIP1 / RING1 | Channel 1 line interface | High-voltage differential pair; requires ≥2.5 kV isolation barrier and 100 Ω series termination for EMI suppression. |
| TIP2 / RING2 | Channel 2 line interface | Independent second POTS port; shares VCC/VEE but has separate bias and protection control logic. |
| SCLK / SDATA / SCEN | Serial configuration interface | 3-wire SPI-compatible bus for runtime parameter programming (ring trip, feed current, impedance). |
| PCM_CLK / PCM_FS / PCM_DI / PCM_DO | PCM data interface | Standard IOM-2 timing; connects directly to codec (e.g., SLICOFI-2) without level-shifting or buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable AC impedance | Adjustable 600 Ω / 900 Ω / complex Z profiles via register writes - ensures compliance with regional line interface standards (e.g., FCC Part 68, ETSI EN 300 326). |
| Integrated ring generator | No external transformer or relay needed - reduces PCB area by >150 mm² and eliminates mechanical wear-out failure modes. |
| Lifeline power mode | Automatic transition to ultra-low-power state (<10 mW/channel) during AC loss - maintains one active line for emergency calls. |
| Remote line diagnostics | On-chip measurement of loop resistance (0–2 kΩ), capacitance (0–4 µF), and foreign voltage (±100 V) - replaces manual multimeter checks. |
| V.90 modem support | Optimized transmit/receive path with <−60 dB crosstalk and <1.2% THD - enables full-speed dial-up fallback in VoIP deployments. |

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 dual-channel TSLIC architecture but uses VQFN-48 package (7 mm × 7 mm); lacks integrated line testing capability. | Preferred for space-constrained designs where diagnostics are handled externally or omitted. | Select when PCB area is critical and remote line test is not required; verify thermal derating for same power dissipation. |
| PEB4364T v1.2 | Dual-channel variant with higher 50 mA feed current and 85 Vrms unbalanced ringing; no lifeline power mode. | Targeted at linecard applications with centralized battery backup, not CPE lifeline use cases. | Choose for carrier-grade access equipment needing higher loop current; avoid for consumer CPE requiring lifeline compliance. |
Compared with PEB4264TV1.2, PEB4264-2V v1.2 trades diagnostic capability for smaller footprint, while PEB4364T v1.2 prioritizes higher drive strength over low-power lifeline operation - making the original optimal for regulated CPE deployments demanding full feature integration and regulatory compliance.

FAQ
What is the maximum allowable loop length supported by PEB4264TV1.2?
The PEB4264TV1.2 supports loop lengths up to 6 km (18 kft) with 24 AWG copper, verified under ETSI Class A conditions at 32 mA feed current and 900 Ω AC impedance. Loop length is programmable via on-chip registers to adapt to local line characteristics and regulatory limits.
Does PEB4264TV1.2 require external components for ringing generation?
No. The device integrates a fully programmable ring generator capable of producing balanced (170 Vrms) and unbalanced (90 Vrms) ringing waveforms without transformers, relays, or external H-bridge drivers. Only external RC snubbers are recommended for EMI suppression on TIP/RING pins.
How is lifeline mode activated and what parameters change?
Lifeline mode activates automatically upon detection of VCC dropout below 2.97 V, switching to ultra-low-power state: feed current reduces to 25 mA, ring amplitude drops to 120 Vrms, and non-critical blocks (e.g., DTMF detection) enter sleep. All settings persist in shadow registers for seamless recovery.
Can PEB4264TV1.2 interface directly with TI's TMS320C54x DSP series?
Yes. Its PCM/IOM interface complies with industry-standard timing (IOM-2 mode), supporting direct connection to TMS320C54x McBSP ports at 2.048 MHz frame sync and 8 kHz sampling. No glue logic or level shifters are required when both devices operate at 3.3 V I/O.
