PEB3265H-V13

Telecom Overview

The Infineon PEB3265H-V13 is a dual-channel Subscriber Line Interface Codec Filter (SLICOFI-2) designed for telephony analog linecard applications. It interfaces between analog subscriber loops and digital PCM highways, converting two-wire lines to four-wire signals. Manufactured in a 0.35 µm 3.3 V CMOS process, it supports 8 kHz and 16 kHz PCM transmission via selectable IOM-2 or PCM/µC interfaces. The device integrates BORSCHT functions, including programmable battery feed, ringing, signaling, coding, hybrid conversion, and testing. It features an Enhanced Digital Signal Processor (EDSP) enabling advanced capabilities such as DTMF generation and detection, Caller ID FSK modulation, Universal Tone Detection (UTD), and adaptive Line Echo Cancellation (LEC).

Telecom Feature Summary

• Integrated Enhanced Digital Signal Processor (EDSP) supporting DTMF generation/detection, Caller ID FSK modulation, Universal Tone Detection (UTD), and adaptive Line Echo Cancellation (LEC).
• Fully programmable dual-channel codec architecture allowing independent configuration of DC feed characteristics, AC impedance matching, transmit/receive gain, hybrid balance, and frequency response.
• Supports internal balanced/unbalanced ringing up to 85 Vrms balanced / 50 Vrms unbalanced, with external ringing support capability.
• Compliant with ITU-T Recommendation Q.552 for interface Z, ITU-T Recommendation G.712, and applicable LSSGR standards.

Telecom Applications

• Telephony analog linecards in telecom provider central offices
• PBX systems requiring message waiting lamp support
• Three-party conferencing implementations

Telecom Procurement Notes

Verify the specific suffix 'V13' against official documentation to confirm package type and temperature grade. Confirm compatibility with required SLIC devices (PEB 4265/-2, PEB 4266, PEB 4264/-2) for the DuSLIC chipset implementation. Ensure design adheres to life-support system restrictions if applicable.

Telecom Selection Notes

Select the PEB3265 over PEB3264 variants when advanced DSP features are required, specifically DTMF decoding, Caller ID generation, UTD, and LEC. Verify interface requirements; this device supports both IOM-2 and PCM/µC modes. Ensure the paired SLIC device matches the high-voltage interface needs (SLIC-E/-E2/-P vs SLIC-S/-S2).

Telecom Part Context

The PEB3265 is part of the SLICOFI-2x family within the DuSLIC chipset, which splits traditional SLIC functions into high-voltage (SLIC) and low-voltage (SLICOFI-2x) components. It is manufactured using an advanced 0.35 µm 3.3 V CMOS process technology optimized for power efficiency and digital signal processing reliability.
