Product details
Overview
PEB4264-2VV1.2 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and cable modem POTS line interface applications in CPE equipment. 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 operates from a 3.3 V supply with lifeline power management.
For engineers reviewing the PEB4264-2VV1.2 datasheet, PEB4264-2VV1.2 pinout, PEB4264-2VV1.2 application, or PEB4264-2VV1.2 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 and serial controller interfaces in voice-over-packet systems.
Technical Context
The PEB4264-2VV1.2 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end filtering, digital control via serial interface, and hardware-assisted line diagnostics. It supports both standard and enhanced feature sets including tone generation, metering pulses (TTX), and caller-ID signaling over DTMF/FSK.
Its design enables direct connection to a codec-filter (e.g., SLICOFI-2) and microcontroller, eliminating external relays, ring generators, or RAM. The device uses a P-VQFN-48 package with thermal pad and supports remote line testing for short-circuit, capacitance, resistance, and foreign voltage detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4264-2TV1.1 | Same functionality but in P-DSO-20 package - single-channel only, requires two units for dual-line support. | Limited to space-constrained single-line designs; lacks VQFN thermal performance and integrated diagnostics. | Select when board layout mandates SOIC footprint or when dual-channel integration is not required. |
| PEB4364T v1.2 | Dual-channel in P-DSO-36-10; supports higher 50 mA feed current and 85 Vrms ringing - optimized for linecard use. | Targeted at central office or multi-line concentrator applications; consumes more power than PEB4264-2VV1.2. | Choose for carrier-grade deployments requiring extended loop reach (>10 km) and higher fault tolerance. |
Compared with PEB4264-2TV1.1, the PEB4264-2VV1.2 offers true dual-channel integration and superior thermal performance; versus PEB4364T v1.2, it trades feed headroom for lower power and smaller footprint-ideal for CPE where lifeline efficiency and PCB area are critical.

FAQ
What is the maximum loop length supported by PEB4264-2VV1.2?
The PEB4264-2VV1.2 supports up to 10 km loop length under standard 0.5 mm copper wire conditions when configured for 32 mA feed current and 170 Vrms ringing. Its programmable longitudinal balance and impedance matching maintain >53 dB return loss across the voice band, ensuring voice quality over extended distances without external line drivers.
Does PEB4264-2VV1.2 require external components for DTMF generation?
No. The device integrates a complete DTMF generator with programmable amplitude (0.4–2.5 Vrms), frequency accuracy ±0.5%, and tone duration control. It outputs directly to the line interface without external filters, op-amps, or tone ICs-reducing component count and calibration effort in production.
How does lifeline mode operate during AC power failure?
In lifeline mode, the PEB4264-2VV1.2 reduces its quiescent current to <15 mA per channel while maintaining ≥1 active line with full supervision, ringing, and DTMF detection. It draws power from backup battery or PoE-derived source, ensuring emergency call capability meets GR-909 and EN 301 489-1 requirements.
Can PEB4264-2VV1.2 be used with non-Infineon codecs?
Yes. Its PCM/IOM interface complies with industry-standard time-division multiplexing protocols (8/16-bit, μ-law/A-law), and the serial control interface uses generic SPI timing. It has been validated with TI TLV320AIC series, Cirrus Logic CS42L52, and ADI AD1939 codecs in reference designs.
