Product details
Overview
PEB3264-0HV1.4 from Infineon Technologies is a dual-channel POTS line interface IC (SLIC) in the DuSLIC chipset family, designed for Customer Premise Equipment and VoIP/VoDSL access gateways. It integrates programmable DC feeding (32 mA), balanced/unbalanced ringing (up to 170 Vrms), and line echo cancellation (8 ms), supporting lifeline operation with 3.3 V supply and PCM/IOM digital interface.
For engineers reviewing the PEB3264-0HV1.4 datasheet, PEB3264-0HV1.4 pinout, PEB3264-0HV1.4 application, or PEB3264-0HV1.4 equivalent, this device is selected for telephony system design requiring integrated line testing, DTMF detection, CLIP generation, and V.90 modem compatibility without external relays or ring generators.
Technical Context
The PEB3264-0HV1.4 implements a fully programmable dual-channel SLIC architecture with integrated analog front-end filtering, on-chip ring generator, and serial controller interface for host µC configuration. It supports both standard and enhanced feature sets including tone generation, metering pulses (TTX), and caller-ID (CLIP) via DTMF/FSK.
Its line testing capability enables remote measurement of short-circuits, foreign voltage, capacitance, and resistance - eliminating field service visits. The device operates in lifeline mode with full control over feeding current, ring-trip threshold, and loop-length compensation while maintaining ≤2.5 Vrms AC impedance compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB3264F v1.4 | Lacks internal ring generator; requires external relay-based ringing circuit | Suitable only where space and cost allow discrete ring components; not lifeline-certified | Select when lower BOM cost outweighs board area and reliability trade-offs |
| PEB3265H v1.3 | Higher DC feed (50 mA), supports longer loops but consumes more power; no lifeline optimization | Better suited for central office line cards than CPE; incompatible with 3.3 V-only designs | Prefer for carrier-grade linecards needing extended reach beyond 5 km |
Compared with PEB3264F v1.4, the PEB3264-0HV1.4 delivers integrated ringing and lifeline support in same footprint; versus PEB3265H v1.3, it trades loop reach for ultra-low power and 3.3 V compatibility - making it optimal for space-constrained, battery-backed CPE.

FAQ
What is the maximum supported loop length for PEB3264-0HV1.4?
The PEB3264-0HV1.4 supports loop lengths up to 5 km with standard 24 AWG twisted-pair cable, verified under ITU-T G.961 conditions at 32 mA DC feed and ≤2.5 Vrms AC impedance. Loop-length compensation is software-programmable via its serial interface to maintain signal integrity across variable line impedances.
Does PEB3264-0HV1.4 support both balanced and unbalanced ringing?
Yes - the device integrates dual-mode ringing circuitry supporting both balanced (170 Vrms) and unbalanced (90 Vrms) configurations, selectable per channel via register programming. This eliminates external transformer selection and enables single-BOM deployment across global telecom markets with differing ringing standards.
Can PEB3264-0HV1.4 operate without an external crystal or clock source?
No - the device requires an external 2.048 MHz or 4.096 MHz master clock for PCM timing synchronization. Its internal PLL generates required internal clocks but does not replace the need for a stable external reference; no onboard oscillator is integrated.
Is line testing functionality accessible through standard interfaces?
Yes - line testing (short-circuit, capacitance, resistance, foreign voltage) is executed via the serial controller interface using documented command sequences. Results are returned as digital values over SDATA; no additional test hardware or firmware drivers beyond Infineon's SLIC API are required.
