Product details
Overview
PEB4264-2TV1.1GD from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for POTS line interface in VoIP, VoDSL, and cable modem CPE applications. It delivers 32 mA DC feed current per channel, supports balanced/unbalanced ringing up to 170 Vrms, integrates line echo cancellation (8 ms), DTMF detection, CLIP generation, and programmable AC/DC parameters - all in a P-DSO-36-10 package.
For engineers reviewing the PEB4264-2TV1.1GD datasheet, PEB4264-2TV1.1GD pinout, PEB4264-2TV1.1GD application, or PEB4264-2TV1.1GD equivalent, this device serves as a fully programmable, low-power SLIC solution with integrated line testing, lifeline support, and V.90 modem compatibility - critical for carrier-grade residential gateways and multi-line VoIP adapters.
Technical Context
The PEB4264-2TV1.1GD implements a dual-channel analog front-end with independent DC feed control, programmable longitudinal balance, and integrated ring generator eliminating external relays. It supports PCM/IOM-2 serial interface and features on-chip tone generation for DTMF, metering pulses (TTX), and caller-ID (CLIP) in FSK/DTMF format.
Its architecture enables remote line diagnostics - measuring short-circuit, foreign voltage, capacitance, and loop resistance - without field service visits. Power management includes lifeline mode ensuring at least one active line under remote feeding, with 3.3 V SLIC operation enabling full 3.3 V system designs.
Key Specifications

Pinout & Package
PEB4264-2TV1.1GD is housed in a thermally enhanced P-DSO-36-10 package (15.9 × 14.2 mm, 1.0 mm height), featuring exposed thermal pad for PCB heatsinking and 36 leads with gull-wing terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply (3.3 V) | Primary digital/analog core power rail; decoupling required within 5 mm for noise immunity. |
| VNEG | Negative supply (–48 V) | Provides DC loop feed voltage; connects to central office battery via external filter network. |
| VRING | Ringing supply (+5 V) | Drives internal H-bridge ring generator; isolated from VDD/VNEG to prevent coupling into voice path. |
| TX0/TX1 | PCM transmit data (ch0/ch1) | Serial output carrying digitized voice from codec; IOM-2 timing aligned to FS and BCLK. |
| RX0/RX1 | PCM receive data (ch0/ch1) | Serial input carrying digitized voice to codec; supports 8/16-bit μ-law/A-law formats. |
| FS | Frame sync | Indicates start of PCM frame; 8 kHz rate for two 64 kbps channels in time-division multiplexed mode. |
| BCLK | Bit clock | 2.048 MHz master clock for PCM data transfer; sourced from host processor or codec. |
| LINE0+/LINE0– LINE1+/LINE1– | Differential line interface | Direct connection to telephone line pair; integrated hybrid circuit enables 2-wire to 4-wire conversion. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable AC impedance | Configurable Z-balanced (200 Ω || 680 nF) or Z-complex (ITU-T G.113 compliant) per channel via SPI register writes. |
| Integrated DTMF/CLIP engine | Hardware-accelerated tone detection and generation eliminates CPU overhead and ensures <150 ms CLIP latency. |
| Lifeline power mode | Reduces quiescent current to <15 mA per channel while maintaining ring trip, off-hook detection, and basic voice path. |
| Remote line diagnostics | Measures loop resistance (0–5 kΩ), capacitance (0–5 μF), and foreign voltage (±100 V) using internal ADC and calibrated current sources. |
| No external ring relay | Monolithic H-bridge ring generator supports balanced/unbalanced outputs - removes mechanical relay failure point and reduces BOM count by 3 components. |

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 pinout and feature set; upgraded version with improved ESD rating (HBM 4 kV vs. 2 kV) and tighter DC feed tolerance (±3% vs. ±5%). | Preferred for new designs targeting IEC 61000-4-2 Level 4 compliance and production ramp after Q3 2005. | Select when higher robustness against board-level ESD events is required and firmware is updated to support new register map offsets. |
| Si3217x (Skyworks) | Single-channel SLIC with integrated codec; requires two units for dual-line operation; uses different SPI protocol and lacks built-in line testing. | Suitable for cost-sensitive, space-constrained designs where voice processing is co-located on same die. | Choose only if migrating from Skyworks platform or requiring integrated codec to reduce external component count despite higher total BOM cost. |
Compared with PEB4264-2V v1.2, the PEB4264-2TV1.1GD offers identical functionality but with earlier qualification status and broader distributor stock availability; versus Si3217x, it provides true dual-channel integration, superior line diagnostics, and direct compatibility with Infineon's DuSLIC ecosystem - reducing firmware development effort by ~200 engineering hours.

FAQ
What is the maximum loop length supported by PEB4264-2TV1.1GD?
The device supports up to 5.5 km of 26 AWG twisted-pair copper loop under standard GR-909 conditions (32 mA feed, 200 Ω line impedance). This is achieved via adjustable DC feed voltage headroom and adaptive longitudinal balance control, verified per ITU-T K.21 surge immunity and G.96 ringing waveform specifications.
Does PEB4264-2TV1.1GD require external components for ringing generation?
No. The device integrates a monolithic H-bridge ring generator capable of delivering balanced 170 Vrms or unbalanced 90 Vrms output directly from the VRING pin. External components are limited to passive filtering (RC snubber and common-mode choke) per ETSI EN 300 386 Class A emissions requirements.
Can PEB4264-2TV1.1GD operate with a single 3.3 V supply?
Only the digital core operates from 3.3 V (VDD); the analog line interface requires three separate supplies: 3.3 V (VDD), –48 V (VNEG), and +5 V (VRING). The –48 V rail is mandatory for DC loop feed and cannot be synthesized from 3.3 V due to power efficiency and thermal constraints.
How is line testing performed without external test equipment?
Internal current sources and ADCs measure loop resistance, capacitance, and foreign voltage by injecting calibrated test tones (1 kHz, 2 kHz) and sampling resulting voltage/current responses. Results are reported via SPI register reads - enabling automated factory calibration and remote diagnostics through host MCU firmware.
