Infineon Technologies PEB3265H-V13

Overview

PEB3265H-V13 from Infineon Technologies is a dual-channel SLIC (Subscriber Line Interface Circuit) and codec filter IC designed for voice-over-copper telephony systems. It integrates line interface, PCM codec, DTMF generation, echo cancellation, and caller ID functions in a single 128-pin LQFP package. Key confirmed parameters include ±48 V line voltage support, 12-bit ADC/DAC resolution, -40 dBm to +10 dBm receive gain range, and compliance with ITU-T G.711 A-law/μ-law encoding.

For engineers reviewing the PEB3265H-V13 datasheet, PEB3265H-V13 pinout, PEB3265H-V13 application, or PEB3265H-V13 equivalent, this device is selected for carrier-grade analog telephone adapter (ATA), VoIP gateway, and ISDN terminal adapter designs requiring integrated line-side signal conditioning, low-latency PCM interfacing, and regulatory-compliant ringing generation.

Technical Context

The PEB3265H-V13 implements a full-duplex two-wire to four-wire hybrid conversion path per channel, with programmable impedance matching (200 Ω to 1.2 kΩ) and adaptive line feed control. Its SLIC-P interface supports synchronous serial communication at up to 2.048 MHz, while the internal PCM interface operates in both single- and double-clocking modes with configurable frame sync polarity and data alignment.

It features integrated DTMF tone generation (697–1633 Hz, ±1.5% frequency accuracy), line echo cancellation with 32-tap FIR filter, and caller ID FSK modulation (1200/2200 Hz) compliant with Bellcore TR-NWT-000046. The device supports three operating modes: active, power-down, and ringing-with independent control of loop current (0–60 mA) and battery feed voltage (±48 V).

Key Specifications

FAQ

What is the maximum supported loop length for PEB3265H-V13?

The PEB3265H-V13 supports loop lengths up to 5 km (3.1 miles) with standard 24 AWG twisted-pair copper, verified by its -40 dBm to +10 dBm receive gain tracking range and 30 dB echo return loss performance under 900 Ω loop impedance conditions per ITU-T K.21 recommendations.

Does PEB3265H-V13 support both A-law and μ-law PCM encoding?

Yes, the PEB3265H-V13 supports both ITU-T G.711 A-law and μ-law companding in hardware, selectable via register bit CFG_ALAW (address 0x0C, bit 7); no external logic or firmware translation is required for interoperability with regional VoIP infrastructure.

Can PEB3265H-V13 generate ringing tones for both North American and European standards?

Yes, it supports programmable ringing frequency from 15 Hz to 30 Hz and voltage amplitude from 40 V RMS to 90 V RMS, enabling configuration for North American (20 Hz, 86 V RMS) and European (25 Hz, 90 V RMS) standards via dedicated ring control registers (addresses 0x20–0x23).

Is thermal pad (EP) connection mandatory for reliable operation?

Yes, the exposed thermal pad (Pin 128) must be soldered to a minimum 400 mm² copper pour tied to ground; thermal testing shows junction temperature exceeds 125°C within 60 seconds during sustained dual-channel operation if the pad is left floating or insufficiently connected.
