Product details

Overview

PEB3264HV14XP from Infineon Technologies is a dual-channel SLIC (Subscriber Line Interface Circuit) optimized for POTS interface in VoIP, VoDSL, and cable modem CPE applications. It delivers 32 mA DC feed current per channel, supports up to 170 V balanced ringing voltage, integrates line testing (short-circuit, capacitance, foreign voltage), and operates from ±5.0 V supplies with programmable AC/DC parameters.

For engineers reviewing the PEB3264HV14XP datasheet, PEB3264HV14XP pinout, PEB3264HV14XP application, or PEB3264HV14XP equivalent, key selection criteria include its dual-channel SLIC architecture, integrated line diagnostics, balanced/unbalanced ringing support, and compliance with lifeline power requirements for emergency telephony service.

Technical Context

The PEB3264HV14XP implements a fully programmable dual-channel SLIC with independent control of longitudinal balance, loop current, ring-trip threshold, and feeding voltage per channel. It supports both balanced and unbalanced ringing configurations without external relays.

Its integrated line-testing capability performs real-time measurement of line voltage, current, and tone response to detect shorts, open circuits, foreign voltage, and line capacitance-enabling remote diagnostics and eliminating on-site service visits.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	Dual independent SLIC channels for two POTS lines
DC Feed Current	32 mA per channel - meets GR-909 lifeline current requirement
Ringing Voltage	170 Vrms balanced - sufficient for global POTS ringing standards
Supply Voltage	±5.0 V - enables direct integration with standard SLIC power rails
Longitudinal Balance	53 dB - ensures low crosstalk and noise immunity in analog voice paths
Line Testing	Integrated short-circuit, foreign-voltage, capacitance, resistance detection - eliminates need for external test circuitry

Pinout & Package

PEB3264HV14XP is housed in a P-DSO-36-10 package (36-pin dual-row SOIC, 10 mm body width, 1.27 mm pitch), optimized for thermal dissipation in high-voltage SLIC operation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC, V_EE	Positive/Negative supply rails	Accept ±5.0 V input; decoupling required for stable high-voltage switching
TIP1, RING1 / TIP2, RING2	Line interface terminals	Direct connection to telephone line pairs; support balanced/unbalanced ringing via internal H-bridge
REFIN1, REFIN2	Reference input for feedback	Enable closed-loop DC feed regulation per channel using external sense resistors
TESTIN, TESTOUT	Line diagnostic I/O	Interface for injecting test tones and measuring return response during remote line testing
CTRL1–CTRL4	Digital control inputs	Configure ring-trip threshold, feed current, longitudinal balance, and test mode via parallel interface

Key Features

Feature	Design Value
Programmable ring-trip threshold	Adjustable per channel to match local loop-length and battery-voltage conditions
Integrated line testing	Measures line impedance, shorts, foreign voltage, and capacitance without external instrumentation
Low-power lifeline mode	Maintains one active line at reduced power during mains failure for emergency calling
Balanced/unbalanced ringing	Configurable per channel via register setting - no external relay or transformer needed

Applications

Voice over IP Gateway

Cable Modem Telephony Adapter (eMTA)

Use Scenario: Residential gateway providing analog phone ports over broadband IP networks.

IC Role / Device Role / Timing Role: Dual-channel SLIC managing line feeding, ringing, and off-hook detection for two concurrent POTS lines.

Use Value: Enables carrier-grade voice service with integrated diagnostics, reducing field-service costs and improving QoS monitoring.

Use Scenario: Embedded telephony in DOCSIS-compliant cable modems supporting multiple analog extensions.

IC Role / Device Role / Timing Role: SLIC provides regulated DC feed, programmable ringing, and echo-tolerant line interface for VoCable operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel SLIC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PEB3264-2H v1.4	Same pinout and function but rated for 3.3 V SLIC supply (not ±5 V); lower max ringing voltage (90 Vrms)	Targeted at low-power CPE designs where ±5 V rails are unavailable	Select when system uses 3.3 V SLIC supply and does not require 170 V ringing compliance
PEB4264T v1.1	Single-channel DSO-20 variant; identical electrical specs per channel but half the channel count	Suitable for single-line gateways or cost-sensitive designs requiring only one POTS port	Choose when dual-channel density is unnecessary and board area must be minimized

Compared with PEB3264-2H v1.4, the PEB3264HV14XP supports higher ringing voltage and ±5 V operation essential for global lifeline compliance; versus PEB4264T v1.1, it doubles channel count without increasing per-channel footprint or thermal load.

FAQ

Does PEB3264HV14XP support lifeline operation?

Yes. It supports lifeline mode by maintaining regulated DC feed on at least one channel during primary power loss, using backup supply paths. Its 32 mA per-channel feed current and low quiescent power meet GR-909 and ETSI EN 300 386 requirements for emergency telephony service.

What is the maximum allowable loop length supported?

The PEB3264HV14XP supports up to 5 km of 0.5 mm copper loop under standard 48 V battery conditions, based on its 32 mA feed current and programmable longitudinal balance. Loop length is adjustable via software-controlled feed voltage and current settings.

Can it generate both balanced and unbalanced ringing on the same device?

Yes. Each channel independently supports balanced (differential) or unbalanced (single-ended) ringing via internal H-bridge configuration controlled by digital registers-no external relays or transformers required.

Is external filtering required for EMI compliance?

Yes. While the device includes internal current-sense and feedback paths, external LC filters on TIP/RING outputs and supply rails are required to meet FCC Part 15 and ETSI EN 55022 Class B radiated emissions limits in typical CPE layouts.
